Particle Size Reduction Equipment: Why Homogenizers Stand Out

Posted by David Shechter on Feb 9, 2019 10:00:00 AM

particle size reduction equipmentReducing large materials into smaller ones is a common and often necessary occurrence in the natural world. From the earth itself eroding to food being digested to rocks being broken into tools, the physical process of reducing something into smaller bits frequently permits advantages (or wonders!) that otherwise wouldn’t exist. Take, for instance, the splendor of the Grand Canyon or the awe-inspiring fact that our bodies can break apart food and air and water into life sustaining nutrients or the many ways humans have made valuable tools from rocks and wood and other resources. Indeed, the world’s very first tool — the hammerstone — was made by ancient hominids and served a purpose not unlike today’s own particle size reduction equipment: to turn something bigger into something smaller.

Modern particle size reduction equipment is categorized according to four basic types:

  • Crushers - which break apart large particles into smaller ones
  • Grinders - which further crumble crushed particles into powder
  • Ultrafine Grinders - which pulverize ground powder into pieces 1-50 micrometers in size
  • Cutters - which yield particles of a specific shape and size

Considering product hardness, consistency and volume (many machines are better suited for certain capacities), companies may use one or more of the equipment types. Many pharmaceutical companies, for instance, opt for ultrafine grinders that can reduce active pharmaceutical ingredients into superfine particles to increase bioavailability. Baby food and soup manufacturers, on the other hand, might need cutting capabilities to ensure that all food pieces in their products are similarly sized. Some manufacturers might use crushing techniques followed by grinding ones or run their products through one system multiple times. It really just depends on the overall purpose of the product being manufactured, the initial ingredient composition and how much money a company has to spend.

With all this in mind, savvy manufacturers started considering the use of high pressure homogenizers as a fifth alternative for businesses in need of particle size reduction equipment. Homogenizers effectively mix together two normally immiscible substances using high pressure. A happy result of the process: homogenizers also reduce particle size! For manufacturers looking to make an equipment investment that not only works, but works across numerous applications, a high pressure homogenizer has become a solid choice. Unlike traditional particle size reduction equipment that only makes use of one type of mechanical force, a high pressure homogenizer utilizes several different ones. And at BEE International, our proprietary system not only uses turbulence, cavitation, high shear and impact to break apart product, it also has modular components that can be customized for specific purposes. Turbulence and cavitation treatments can be altered, shear times can be reduced or lengthened and impact and intensity can be tweaked. So, just want does all this mean? 

The Benefits of Using High Pressure Homogenizers (HPHs) as Particle Size Reducers:

  1. HPHs produce tighter distribution of smaller particles.

  2. HPHs achieve better particle reduction in fewer passes.

  3. HPHs increase manufacturing efficiency.

  4. HPHs reduce manufacturing costs.

  5. HPHs help create products with longer shelf lives, increased bioavailability and improved sensorial and biophysical properties.

2 Types of High Pressure Pasteurization Equipment

Posted by David Shechter on Jan 17, 2019 7:06:25 PM

two types of high pressure pasteurization equipmentIn the mid 19th century, Louis Pasteur helped France safeguard its beer and wine industries by establishing a manufacturing process that preserved and protected alcoholic products from spoilage during export. The principles of that system, eventually known as pasteurization, were based on his observations not only that microorganisms could change the molecular makeup of substances, but that they could be killed when exposed to high temperatures. Coupled with the scientific significance of French chef Nicolas Appert’s previous research on sterilization and canning techniques, thermal pasteurization quickly became the de facto approach for food manufacturers wanting to guarantee the safety and preserve the quality of their liquid and some semi-solid products.

The only problem: exposure to extreme temperatures often changes the way a food tastes, as well as its nutritional value. Believing that neither should have to be sacrificed because of safety and preservation concerns and buoyed by additional scientific advances, as well as increasing public interest in clean eating, more and more manufacturers are starting to use a high pressure processing system (HPP or pascalization) instead of heat to pasteurize their products. HPP effectively removes most pathogens and other harmful microorganisms and extends shelf life, but does not alter a food’s nutritional content, its color or its flavor. Take a look at the two most common types of high pressure pasteurization equipment: 

Water Tanks for Prepackaged Food Pasteurization

Certain prepackaged liquid and solid food items can be pasteurized using a large steel tank filled with a liquid (usually water). After the packaged food is loaded in to the tank, pumps apply pressure that changes the food’s cell structure, effectively inhibiting cell division and killing most microorganisms. According to food science research at Rutgers University, “vegetable and fruit products such as juices, salsa, dressing and guacamole; meat products such as ready-to-eat deli meats and poultry; and seafood such as shellfish and fish products” can all be processed using a high pressure pasteurization technique. The tank method is capable of processing a lot of food at one time, making it a good choice for manufacturers with high volume productions.

Homogenizers for Liquids and Semi-Solid Pasteurization

Liquids and some semi-solid products can also be pasteurized with high pressure homogenizers that push them through a series of tubes using a hydraulic pumping system that creates pressure and sterilizes them. The homogenizer then expels the product through a small opening with a drop in pressure that forces cell rupture, breaking the product apart into equally sized pieces that can be easily and uniformly mixed. Combining the pasteurization and homogenization process allows manufacturers to more efficiently manage their time, reducing their energy use and waste, and serves as a viable alternative to thermal pasteurization in the milk and juice industries especially.

Homogenizers for Cannabis: How To Deliver More Consistent & Uniform Particle Size

Posted by David Shechter on Nov 29, 2018 11:30:00 AM

homogenizers for cannabisIf you’re looking into cannabis processing options, homogenization might seem a bit complicated at first. While there are certain elements to homogenization that are technical, homogenization is actually a pretty simple process! When it comes to particle size reduction, homogenizers work to combine two or more ingredients in a uniform manner. Since homogenization is mechanical, it doesn’t involve adding preservatives or other materials to the mixture. Thanks to pressure and other forces, particles become uniformly dispersed in the homogenization process.

When it comes to cannabis products, one of the best benefits a homogenizer can offer is how they deliver more consistent and uniform particle sizes in their dispersions. Here are the top three reasons why this should matter to you:

1. No More “Hot” and “Cold” Spots

As mentioned above, when you homogenize two or more ingredients, those particles are reduced to a small size and uniformly dispersed throughout the mixture. So without homogenization, there’s not a good way to determine where the cannabinoids are in your products. Therefore, you may have one item that is chock full of cannabinoids while the next item doesn’t have any. In fact, a recent study found 31% of cannabis products tested did not contain the amount of cannabinoids their labels claimed. That’s an unacceptable number in any industry, but can be particularly embarrassing for companies that are looking to establish themselves in the relatively new commercial cannabis industry.

2. Increased Drug Efficacy

Next, a smaller particle size will have a greater total surface area which can increase the rates of dissolution and absorption of any active ingredient. Therefore when working with cannabis, you need to ensure your products have small, uniform particle size for a greater absorption rate and there’s no better way to do this than using a homogenizer. Homogenizers can help you reach your target particle size reliably plus you can run a filter through the end product to see that all particles are the target size. Further, smaller particles can increase bioavailability by up to 75% by increasing the surface area and you can actually reduce the active ingredient required to achieve the same effect.

3. Product Appearance

While this doesn’t apply to cannabis products alone, a smaller, more uniform particle size can be beneficial for aesthetic reasons. When particles are homogenized properly, the end product can appear smoother and more homogenous. Therefore, when looking to add cannabis to lotions, food products, and other items, having a beautiful product can make all the difference when it comes to sales.

Final Thoughts

There’s a long history of businesses across all industries using homogenizers to guarantee uniformity in their product, which is something that everyone in the cannabis industry should want when creating new products. Plus, consumers want to associate with brands and products they can trust. So when you use high-pressure homogenizers in your process, you'll be keeping the promises you already make to your customers.

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. 
  • Processing range.

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.

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.

Lessons on Selecting a Laboratory Homogenizer

Posted by David Shechter on Mar 26, 2018 2:10:06 PM

Top view of businessman legs choosing his way-747702-edited.jpegMost of us have experienced the activity (or drudgery) of purchasing an automobile, and the process of selecting one can be extremely tedious. There are a wide array of manufacturers, models, colors and sizes from which to choose and even more options within those choices.

Fortunately, selecting a laboratory homogenizer that best meets your business needs doesn’t have to be as complicated. If you purchase a model that accommodates your required applications, it should be able to serve your homogenization needs for the long-term. Even though all laboratory homogenizers can accomplish emulsions, cell disruptions and more, understanding the commercially available homogenizing methods can make it simpler to determine the right homogenizer for a particular application.

Main Methods of Homogenization

The primary homogenization methods include ultrasonic, mechanical and high-pressure. Ultrasonic homogenizers, or sonicators, are used in cell lysis and particle size reduction applications. They are best utilized for samples which are incredibly difficult to disrupt, including tough animal tissues, spores, soil samples and liposomes. Although they are often used to process small samples in suspension and do not require pre-grinding or cutting, ultrasonic homogenizers generate heat, which can harm temperature-sensitive samples.

Mechanical homogenizers work by using pressure (shearing) and/or force to disrupt cells. They produce consistent results quickly and are able to alter a sample’s physical structure while maintaining its chemical composition. The mechanical homogenization method provides for easy scalability and especially well-suited for animal tissues and cells.

Probably the most commonly utilized method, high-pressure homogenizers have the capability to lyse cells and create emulsions, thereby enabling a longer product shelf life and an even distribution of active ingredients. They are one of the most efficient fluid processing systems for cell disruption and particle size reduction, especially for applications which require minimum particle sizes and homogenous mixtures. High-pressure homogenizers enable the study of tissues, cells and more.

Factors to consider when choosing a brand and model of laboratory homogenizer include:

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