How to Improve RNA Isolation with Homogenization

Posted by David Shechter on Nov 15, 2018 11:30:00 AM

rna-isolationRNA isolation is, unsurprisingly, a delicate and complicated process that requires diligent execution and precise application. Indeed, even seemingly small mistakes can completely ruin an attempt to extract, isolate, and study RNA samples. With that in mind, today we’re here to explain how homogenization will help improve RNA isolation –– while also sharing a few best practices all professionals can use to boost their results when working with RNA. Check them out below:

Sample Collection and Preservation

Researchers value RNA analysis in no small part because studying RNA can help explain how genes function and are expressed. Regardless of the aim of a given experiment or project though, collecting and preserving samples in the right way is essential to generating viable results with RNA. Some tissues are notoriously difficult to extract RNA from (like bones or roots) and if samples aren’t preserved properly before homogenization, the results of a study can also be affected. As such, researchers should strive to either 1) conduct homogenization immediately following sample collection, which may not always be possible, or 2) freeze the samples using a substance like liquid nitrogen for temporary containment until homogenization can be performed. Note here that thawing frozen samples before homogenization will also affect the outcome of an experiment.

Benefits of Homogenization

The good news about utilizing homogenizers in regard to RNA extraction is that they eliminate the potential of heat production –– since high-pressure homogenizers operate so quickly. In addition, homogenizers are scalable and compatible with a wide array of sample sizes and types. Even if a samples has cell walls that are hard, or when other conditions aren’t ideal, homogenizers can still assist researchers in achieving meaningful yields. Lastly, homogenizers are key to separating samples from RNase, which as we’ll explain below, will significantly alter RNA samples and often render them unusable.

Preventing RNase Exposure

Ribonuclease or RNase, presents a problem for researchers looking to study intact RNA. RNase is an enzyme that catalyzes the degradation of RNA into smaller pieces. This is obviously something researchers want to avoid. Unfortunately, RNase is more or less everywhere, which means that it’s easy to expose a sample to it through lab equipment or on the surface of gloves. Professionals can use special cleaning solutions to ensure their equipment doesn’t spoil their experiment thanks to RNase exposure–– and should change their gloves often throughout their work. Remember also that proper storage at the end of the isolation procedure is also imperative to prevent any outside factors influencing results. RNA is generally stored at low temperatures –– either -20 Cº or -80 Cº depending on how long the storage will last. 

Final Thoughts

With the right equipment and by following guidelines and best practices to the letter, researchers can glean meaningful RNA yields under adverse conditions. At BEE International, we’re passionate about providing scalable, highly effective homogenization solutions for our business partners. We strive to offer the finest products –– and customer service –– in the industry. Don’t just take our word for it, though. Contact us today!

Why We Love High Pressure Homogenizers (And You Should, Too!)

Posted by David Shechter on Aug 30, 2018 11:30:00 AM

Love High Pressure HomogenizersIf you were asked about some of your favorite products, a high-pressure homogenizer may not make the list. However, as we’ve discussed in a previous blog, the homogenization process produces a lot of products you most likely use and consume in your daily life. That’s one of the reasons we here at BEE International love homogenizers…but there are more! Let’s take a look at some of the most popular uses of high-pressure homogenization and the benefits they offer consumers.

Particle Size Reduction

High-pressure homogenization utilizes mechanical force to break down particles or droplets in a liquid into smaller and more uniform sizes, resulting in a dispersion, which is where fine particles of one substance are scattered throughout another substance. Dispersions can be further classified into solutions, suspensions and colloids, a mixture somewhere between a solution and a suspension.

Some high-pressure homogenizers can reduce particle size to as small as a single-digit nanometer. Plus, they ensure the composition is equal throughout, and the overall molecular makeup of the sample isn’t compromised. Many high-pressure homogenizers are able to produce emulsions, dispersions and suspensions at particle sizes of 100 µm or higher, and a select few can achieve a size of down to 0.1 µm. Key benefits of particle size reduction include:

  • Increased dissolution rate.

  • Improved drug delivery.

  • Controlled rate of reaction.

  • Increased density.

  • Consistent texture and product appearance.

  • Enhanced sedimentation stability.

  • Improved mineral processing.


Important Applications

Food and Beverages

Though one of the most well-known uses of high-pressure homogenization in the food and beverage industry is for milk, it is also widely used in the manufacture of sauces, spreads, salad dressings, fruit juices and concentrates, fish and meat pâté, sweeteners, baby food, egg product, other dairy products and more. It helps companies utilize to efficiently, cost-effectively and safely produce their goods. Food homogenizers also aid in the delivery of a product with uniform texture, flavoring and taste through a scalable process that allows for a longer period of freshness than food comprised of larger particles.

Pharmaceuticals, Chemicals and Biofuels

High-pressure homogenizers are used for numerous products from the chemical and biotechnology industries and products such as pharmaceutical tablet coatings, vaccinations and creams. They can be used to create cost effective medicines, modify microorganisms, synthesize new chemicals and develop alternative biofuels.

Cosmetic Creams and Lotions

Due to its ability to provide potent particle size reduction, enriched texture and consistency and strengthened emulsion stability, high-pressure homogenization is a preferred method for improving the production of cosmetic creams, lotions and other cosmetic products. It is especially beneficial for beauty creams and moisturizing lotions because they have to have a combination of the right texture and consistency in order for the skin to be able to effectively absorb them.

RNA Extraction

 Utilizing homogenization for RNA extraction enables processing to be effectively and repetitively processed in only seconds, thereby eliminating heat production. Its force and high pressure produce consistent and uniform samples, and it can process both small and large samples. Plus, homogenizers are scalable and compatible with many sample types, including those with tough cell walls. Using a powerful chaotropic salt solution, RNA extraction purifies RNA from biological samples by quickly disrupting cells or tissue to release the nucleic acids from the cells. These released RNAs are valuable in providing details on which genes are expressed (used to make products), to what degree the genes are active, how they work to regulate each other via small, regulatory RNAs and which structural RNAs (i.e. rRNAs, mRNAs and tRNAs) are produced.

Oil Emulsification

 Due to the fact that water and oil are immiscible, powerful mixing is essential to conducting oil emulsification. Therefore, specialized machines such as high-pressure homogenizers are preferred because they not only impart high shear but also are able to reduce particle sizes much more efficiently than other blending and emulsification methods. They are used in a wide variety of research and scientific uses and by many industries that require the use of active ingredients because they reduce active ingredients to a small enough size to ensure a thorough dispersion throughout the medium produced. Additional benefits of high-pressure homogenization for oil emulsification include production of stable emulsions, improved product consistency, shelf-life, texture, color and flavor and the ability to overcome the resistance caused by two immiscible liquids.

The Ultimate Cheat Sheet for Choosing a Cell Homogenizer

Posted by David Shechter on Aug 16, 2018 11:30:00 AM

Businessman is standing in front of two direction signs.If you attended high school before laptops and tablet computers replaced books and used a landline to make phone calls, you’ve probably heard of CliffsNotes. Often used to help students figure out the intricacies of a novel that was required reading for English class, these handy pamphlets were a sort of a study guide highlighting the work’s key points.

In this blog, we’re offering you a CliffNotes version of tips for selecting a cell homogenizer that best meets your business needs. We’ll outline cell homogenization, often referred to as cell lysis, offer key factors for how best to achieve it and provide some benefits on it.

What is Cell Lysis?

Cell lysis, which takes place in biotech, pharmaceutical, food, cosmetic and chemical laboratories on a regular basis, is the rupture of the cell membrane resulting in the release of cell contents and the subsequent death of the cell. Research scientists and laboratory technicians disrupt the cell’s structure to extract organelles, proteins, DNA or mRNA. 

Cell lysis can be achieved through mechanical or chemical methods. Mechanical cell lysis techniques include high shear mixing, traditional homogenization, sonication, grinding, freeze/thaw cycles and high-pressure homogenization. Chemical cell lysis techniques include osmotic lysis and the use of detergents, chelating agents or chaotropic agents.

In order for cell lysis to be performed successfully, the following factors should be present:

  • Intracellular proteins should be accessible for extraction and solubilization.
  • The process should be flexible, as different cells require different cell lysis strategies.
  • The technique should result in a high yield in a short time.
  • The process should be relatively easy to perform.
  • Results should be consistently reproducible and scalable.

 

How Homogenization Helps

Of the methods used to achieve cell lysis, the most widely used is homogenization, which offers a multitude of benefits for production laboratories and the consumers who buy their products. It is especially useful for small volumes of cells and/or cultured ones and involves the use of shearing force on the cell. By forcing a small cell through an even smaller-sized orifice, homogenization removes the outer layer and lyses the cell. Some cell lysis products use utilize shear, and others employ sonic cavitation. However, the best choice when purchasing a homogenizer for cell lysis is one that uses shear, cavitation and impact and lets the user adjust the relative amount of each force for different applications.

The homogenizer you choose for cell lysis should be scalable to allow for customization in pressure and intensity, resulting in both cost and time efficiency for the user. It also must accommodate for multiple cell types and adjust for various sample sizes. Other factors to consider when selecting the right cell homogenizer are the force required to produce the highest yield in the least amount of time and the volume, efficiency, stability and sanitary standards compliance of the product. Advantages of using this type of homogenizer are:

  • Accessibility of intracellular proteins.
  • Built-in process flexibility.
  • Ease-of-use and low learning curve.
  • Reproducible and scalable results.
  • Various sample size processing.
  • Ability to disrupt all cell types.
  • Better results in fewer passes.

Making the Right Choice: Homogenizer Manufacturers

Posted by David Shechter on Jul 31, 2018 11:30:00 AM

choosing high pressure homogenizerShopping for certain products is easy. If you want a fast food hamburger, you have a few well-known establishments from which to choose. If you’re looking to purchase some products to stain a deck or tend to weeds in your lawn, you most likely go to your local hardware store or one of a couple bigger, nationwide home improvement stores.

Investing in a more expensive product often requires more research and comparison. Usually, you can read customer reviews online or find ratings published by consumer organizations. When purchasing a homogenizer, however, it may be harder for you to obtain the advice needed to make the right decision.

First, let’s do a little refresher on homogenization. The primary methods used for homogenization include ultrasonic, mechanical and high-pressure, and homogenizers are used across multiple industries, such as:

  • Pharmaceutical: vaccines, antibiotics, cancer treatment and medicinal creams.
  • Food and Beverage: mayonnaise, ice cream, cream liqueurs, salad dressings, dairy products and more.
  • Biotech: creation of cost-effective medicines, modification of microorganisms, synthesization of chemicals and development of alternative biofuels.

Based on these details, the first step in finding a homogenizer manufacturer in asking yourself the following questions:

  1. Why do I need one?
  2. What differentiates one homogenizer from similar ones on the market?
  3. Does my product require a specific particle size?
  4. Which accessories are recommended and/or required for optimal performance?
  5. What motor power does my product require?
  6. Do I have a desired tube capacity and/or mixing speed?

By understanding the available options and what can best help you accomplish your specific homogenization goals, you are better equipped to select a manufacturer to meet your specific needs. It’s important to choose a manufacturer who will work with you to customize a homogenizer that delivers the best possible results. Some companies are able to customize the forces in their homogenizers to suit your application. Some even produce separate homogenizers for each phase of drug development.

Consistency is essential in homogenization, so employing the services of a manufacturer who aids you in reproducing reliable results is imperative. They should offer a homogenizer that is easy to scale and enables the product developer to quickly apply a wide variety of mixing techniques to a formulation. The manufacturer should have a reputation for reliability, offer customer referrals and provide you with at least once demonstration of their product(s).

Once you’ve decided on a manufacturer from which to purchase your homogenizer, factors to consider when choosing a brand and model include:

  • Sample types.
  • Maximum operating pressure. 
  • Mixing speed.
  • Processing setup.

Six Tips for Ensuring Safety When Using Your High-Pressure Homogenizer

Posted by Deb Shechter on Jul 12, 2018 10:30:00 AM

high pressure homogenizerSafety first. It’s a phrase you hear fairly often, and although it may seem unnecessary to repeat, it’s especially important when working with large machines or those with many parts. When not used correctly, these machines can not only fail to produce an optimal product but also cause injury. 

Homogenizers fit into this category, so we’re offering the following tips on how to use yours and the samples it produces both safely and effectively:

1. Wear the appropriate protective equipment.

As with any such machine, these elements are designed to keep the user safe from moving parts and any hazardous chemicals. Whether it’s gloves, eye goggles or even ear plugs, investing in these accessories can keep you from damaging any part of your body, especially your eyes and ears. Some high-pressure homogenizers can reach 85 dBA and potentially cause ear damage.

2. Follow operating instructions and regulations.

There are safety laws and guidelines produced by unions and the government for a reason. These rules are designed to keep you safe while ensuring the machine you’re using is working as it was designed to do. To make sure you always have your high-pressure homogenizer’s instruction manual when you need it, keep it with the machine, and store a copy with your other important documents.

3. Use only the parts that came with your high-pressure homogenizer.

The parts that make up your high-pressure homogenizer are designed to work together and should not be substituted with another accessory or attachment. Failure to follow this rule may cause your product to work at a decreased level or even break, often voiding your warranty.

4. Avoid contact with the rotating shaft and homogenizing head.

Contact with either of these sharp parts can cause injury, so make sure you always switch the machine off before cleaning it or changing screens. Be especially careful when handling your high-pressure homogenizer after it has been contaminated with dangerous samples.

5. Let only trained operators handle your high-pressure homogenizer.

When installing or operating your homogenizer or simply doing maintenance on it, have only those trained to do so perform the task. Improper handling can cause both machine malfunction and minor injury to the handler.

6. Follow common electrical precautions.

Again, these rules are in place for a reason, and failing to follow such rules may result in electrocution or shock.

Homogenizers and the Forces That Drive Them

Posted by Deb Shechter on Jun 25, 2018 11:30:00 AM

forceForce sounds like a very scientific term, but it basically consists of pushing, pulling and gravity. Pushes and pulls set things in motion, while gravity pulls down everything on earth. The six kinds of forces that act on objects when they come into contact with one another are: normal, applied, frictional, tension, spring and resisting.

In high-pressure homogenization, mechanical forces enhance the effectiveness of utilizing extremely high operating pressures. The combination of four main forces – cavitation, high shear, impact and turbulence – are used with high pressure to achieve particle size reduction, cell lysis and/or effective emulsification.

Cavitation

Cavitation occurs when a high amount of pressure is exerted on a liquid sample. Pressure enables the liquid to achieve high kinetic energy, thereby increasing velocity. Also sometimes described as the formation of liquid-free spaces within a liquid, cavitation is especially useful for particle reduction and can be intensified or reduced by adjusting the size of a high-pressure homogenizer’s nozzle.

Although homogenization can be accomplished without cavitation, it increases the efficiency of the process. In the food industry, cavitation in homogenization breaks up large fat globules to create a stable emulsion for increased shelf life and improve taste and texture.

High Shear

High-pressure homogenizers work through shear force, which can be created when a tangential force is applied to a sample. Homogenization using high shear allows for even further reduction of particle size by mixing two normally immiscible phases, such as with water-in-oil (w/o) or oil-in-water (o/w) emulsions.

Many high shear mixers are used to reduce particle size, but high-pressure homogenizers are able to attain even higher shear rates. This is especially important when a dispersion is required.

Impact

The force of impact works in homogenization to reduce the particle size of solids into liquids and achieve lysis of difficult-to-disrupt cells and other materials though the use of grinding beads. Dounce and Potter-Elvehjem homogenizers use only the force of impact to lyse cells, while the French press counterpart adds in high shear. The ability of high-pressure homogenizers to combine multiple forces offers manufacturers better yield in fewer passes and a lower time requirement. Along with other mechanical forces, impact can be fine-tuned to accommodate a specific sample.

Turbulence

In the overall homogenization process, turbulent premixing is the stage designed to prepare a sample by mechanically loosening bonds. By high-pressure machines like stirrers and agitators putting a sample through turbulent premixing, the homogenization process is easier and more time-efficient.

Another influence in homogenization is process intensity; higher intensity is used to obtain smaller particle sizes in fewer passes. Though not all homogenizers are equipped with adjustable process intensities, those from BEE International allow for increased or reduced process intensity with only the turn of a dial.

BEE International: The Driving Force Behind the Best High-Pressure Homogenizers

Unlike other technologies which apply one mechanical force to mix a product, BEE technology utilizes all available mechanical forces to achieve optimum results. We synergistically combine and fine-tune these forces to produce the best possible product for you and let you produce a tight distribution of small, uniform particles every time.

Summer, Sunscreen, and Homogenization

Posted by David Shechter on Jun 13, 2018 11:30:00 AM

bee1For many people across the United States, the winter of 2017 was one of the coldest on record. Residents of the East Coast had to deal with multiple Nor'easters, shutting down airports and wreaking havoc on roadways.

For most of us, summer and the high temperatures that typically accompany it are definitely welcome. Kids are out of school, baseball games are being played and swimming pools are being opened and prepped for lazy summer days.

With the arrival of summer, though, comes a reminder about the dangers of getting too much sun. More people are diagnosed with skin cancer annually in the U.S. than all other cancers combined, and the annual cost for treating skin cancers in this country is an estimated $8.1 billion.

Skin cancer may be prevented or at least minimized through the regular use of sunscreen. In fact, scientific evidence supports the benefits of using sunscreen to reduce short- and long-term damage to the skin from the sun’s rays.  

High-pressure homogenization is a preferred method for improving the production of cosmetic creams or lotions, including sunscreen, because it offers the following benefits:

Potent Particle Size Reduction

By forcing a sample through a narrow space while applying high pressure and multiple mechanical forces, including cavitation, shear, impact and turbulence, high-pressure homogenization more effectively decreases particle size. This reduction, or micronization, creates a more homogenous mixture, provides better active ingredient dispersion and stabilizes product emulsions. It’s especially beneficial for creams, lotions and other cosmetic products because of the positive effect on the quality of these items. 

Enriched Texture and Consistency

High-pressure homogenization is often preferred over other methods because of it’s capability to create a product that is uniformly mixed. This leads to smoother texture and enhanced consistency, which is essential for beauty creams and moisturizing lotions because they have to have a combination of the right texture and consistency in order for the skin to be able to effectively absorb them. 

Strengthened Emulsion Stability

Semi-solid products such as lotions and creams are comprised of emulsions, which are a mixture of two immiscible liquids. Micronization of droplets acts to eliminate the separation of water phase of homogenization, resulting in a more permanent mixture of oil and water. This permanence extends the shelf life of these semi-solid products and improves their appearance through consistent coloring.

BEEI: Homogenizers for High-quality Creams and Lotions

If you’re searching for a cosmetic homogenizer to meet your laboratory and/or production needs, make sure you choose one that’s high quality and includes a combination of capabilities. Whether your product is a cream, lotion, makeup or personal care item, opting for a customizable high-pressure homogenizer will only improve and enhance its effectiveness.

Homogenization and the Industries That Use It

Posted by Tal Shechter on May 29, 2018 2:00:00 PM

bee2Many people go to a local store to buy food, personal care products, medicine and other items. However, most of us don’t spend any time considering what went into the production of these items. In many cases, it likely involved homogenization.

Homogenization is a process utilized for particle size reduction. It works by forcing a sample through a narrow space, and multiple forces, including turbulence and cavitation in addition to high pressure, can act on the sample to create a high-quality product. It can be used on many different types of material, such as plant, food, soil, tissue and more. Plus, it provides benefits for multiple applications, such as high-pressure pasteurization, dispersions, micro/nano emulsions and cell disruption.

Although many other types mixing machines exist, homogenizers are scalable, and their use of multiple mechanical forces instead of just one results in stable, uniform and consistent products. They are used in a wide variety of research and scientific uses and by many industries that require the use of active ingredients because they reduce active ingredients to a small enough size to ensure a thorough dispersion throughout the medium produced.

Pharmaceutical

Powerful mixing and particle size reduction are key techniques among pharmaceutical products. In the pharmaceutical industry, researchers use homogenizers during laboratory research and in clinical trials and manufacturing for products including vaccines, antibiotics, cancer treatment and medicinal creams. Benefits of homogenization for pharmaceutical products include improve delivery of active pharmaceutical ingredients, increased digestibility, lengthened shelf life and improved reliability in manufacturing settings.

The most important uses for homogenizers in the pharmaceutical industry are particle size reduction, scaling for drug development and synthesis of essential drug components. Though other mixing methods exist, homogenization is the most scalable, resulting in increased cost savings, lower time requirements and a decrease in the likelihood of failure for the product for which its used.

Food and Beverage

Many people identify the use of homogenization in the food and beverage industry with milk; it gives milk a longer shelf life and makes it more stable and visually pleasing. Homogenization is primarily used in the food and beverage industry to help manufacturers improve the composition and quality of their products and ensure their end products meet standards for visual appearance, texture and taste. 

Because homogenization utilizes pressure instead of heat, valuable nutrient content and flavor are preserved, chemical structures are stabilized and food processing outcomes are improved. It is a preferred method for producing emulsions, suspensions and other products that require a liquid suspended in another liquid or a small particle size. These products include mayonnaise, ice cream, cream liqueurs, salad dressings, dairy products and more.

Biotech

The biotech industry is comprised of the fields of cellular biology and molecular biology. Homogenizers are most commonly used in this industry to achieve effective cell rupture, enhanced particle size reduction and nanoparticle production. Although they decrease particle size, they ensure that a composition is equal throughout without compromising the overall molecular makeup of the sample.

Homogenizers also can be used to create cost effective medicines, modify microorganisms, synthesize new chemicals and develop alternative biofuels. In the case of cell disruption, they allow for a variety of cells, including E. coli, yeast, bacteria and delicate animal tissues, to be ruptured to recover the contents of essential cells.

Pharmaceutical Equipment Manufacturers: Five Questions to Ask Before Purchasing a Homogenizer

Posted by David Shechter on May 21, 2018 11:00:00 AM

pharmaceutical equipment manufacturers homogenizerBuying an automobile or house may be a complex process, but you often want to perform detailed research before making such a substantial purchase. You want to ensure your purchase has the capabilities you require, fits within your budget and offers a good investment.

For manufacturers of pharmaceutical equipment, doing research before buying a homogenizer or any other sizable item necessary for production is key to finding the right one. Though this process many seem time-consuming, you’ll end up with a product that best fits your needs and gives you the most benefits. Following are ten questions to ask before buying a homogenizer:

Why do I need one?

Though homogenizers are valuable tools for manufacturers in multiple industries, different models typically address different needs. For instance, maybe you need a homogenizer to mass-manufacture a product that has been approved for market. Or, perhaps you’re conducting research and development and need to disrupt yeast cells. At BEE International, we produce separate homogenizers for each phase of drug development. Make sure the product you choose is best suited to your specific business needs.

What differentiates one homogenizer from similar ones on the market?

In your research for a homogenizer, be sure to ask each manufacturer about their product’s specific capabilities and benefits. Their customer support personnel should be able to articulate any unique functions and/or specifications their products have and define ways it may be more cost-effective than competing products.

Does my product require a specific particle size?

To purchase a homogenizer which provides maximum laboratory output, you should ensure you know the required consistency in texture and size for your product to achieve safety and efficacy. Most pharmaceutical products, including vaccines, inhalants and anesthetics, need to be synthesized using a specific particle size. Many high-pressure homogenizers are able to produce emulsions, dispersions and suspensions at particle sizes of 100 µm or higher, but only a select few can achieve a size of down to 0.1 µm.

Which accessories are recommended and/or required for optimal performance?

Many times, a homogenizer without a lot of bells and whistles will perform the job for which you selected it well. However, some accessories are designed to offer benefits such as time savings, improved process accuracy and enhanced process efficiency. For example, deflector heads can facilitate homogenization of viscous material, generator probes can prevent cross-contamination and pre-assembled bead kits can make the process much easier. Check with each manufacturer to see if any specific accessories are needed for their homogenizing product to run at its highest possible level.

Do you have a demo machine we can test to see if your product meets our needs?

Before you purchase any homogenizer from any manufacturer, it’s important to try each one out to make sure it’s the best fit for your laboratory. For instance, if you handle high volumes of samples, you should try a homogenizer with a high motor capacity for optimal processing efficiency. If you have a desired mixing speed, you should examine homogenizers that let you easily achieve and maintain this speed or change it as necessary.

Other questions to ask when looking to purchase a homogenizer should center around company reputation, product warranties, level of customer service after purchase, user training and education, output capacity and ease of use. Taking the time to select the homogenizer best suited to your needs will be worth the effort.

Particle Size Reduction: Processes and Products

Posted by Deb Shechter on May 8, 2018 2:30:00 PM

particle size reductionBigger is not always better. For instance, many electronic gadgets that have come out over the past few years have a smaller, more streamlined design. Most people want to lose weight to become smaller. Also, I’m glad pests like spiders and cockroaches are as small as they are.

Multiple industries and manufacturers need to be able to reduce the size of particles to achieve their preferred end-product. It affects a product’s color, taste, chemical reaction, density and more. For example: reduced particle size enables creams and lotions to absorb into the skin more rapidly, which is extremely important in the pharmaceutical and cosmetic industries.

Key benefits of particle size reduction include:

  • Increased dissolution rate

  • Improved drug delivery

  • Cleaning product health and safety

  • Controlled rate of reaction

  • Greater sedimentation stability

  • Consistent product texture and appearance

  • Improved mineral processing 

Preferred Product for Particle Size Reduction

One of the most widely utilized methods for particle size reduction is high-pressure homogenization. It uses mechanical force to break down particles or droplets in a liquid into smaller and more uniform sizes, resulting in a dispersion, which is where fine particles of one substance are scattered throughout another substance. Dispersions can be further classified into solutions, suspensions and colloids, a mixture somewhere between a solution and a suspension.  

Some high-pressure homogenizers can reduce particle size to as small as a single-digit nanometer. Plus, they ensure the composition is equal throughout, and the overall molecular makeup of the sample isn’t compromised.

Selection Criteria

How do you know what homogenizer is best for your company’s specific needs? The first consideration is what type of product you need. Which one you select will vary based on whether you want to use it for a specific product or for more general use. identifying the key product(s) you want produce should help guide you in choosing the most suitable homogenizer.

Once you narrow down the product(s), you’ll want to decide what features and capabilities you want in a homogenizer. Depending on whether your product(s) and process requires mechanical forces (like shear, cavitation or impact), high pressure, temperature change or another parameter altogether, you should identify the technical operations needed to make sure you choose the right machine for your needs.

The BEE International Difference

Unlike a hammer mill which uses only one mechanical force (impact), BEE International’s patented homogenization technology utilizes all available mechanical forces. We synergistically combine and fine-tune all available mechanical forces, including turbulence, cavitation, shear, impact and process intensity, to produce the best possible product for you. In addition, we produce a tight distribution of small, uniform particles every time.

Depending on your product, benefits of our products include a longer shelf life, increased bioavailability, improved sensory characteristics and greater productivity along with lower manufacturing costs due to fewer passes.
