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.

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. Our laboratory, pilot and industrial homogenizers all produce reliable and consistent particle size reduction.

Oil-in-Water and Water-in-Oil Emulsions: What's the Difference?

Posted by Deb Shechter on Apr 24, 2018 10:30:00 AM

oil in water and water in oil emulsionsYou’ve no doubt heard the phrase “Oil and water don’t mix.” It’s basically a way of saying certain items or people do not go well together. However, oil and water can mix with the right ingredients – specifically, emulsifiers. Emulsifiers prevent oil and water from separating by establishing a barrier that protects the droplets.

When oil and water are mixed powerfully, they form either oil-in-water (o/w) or water-in-oil (w/o) emulsions. In o/w emulsions, oil is dispersed in a continuous water phase, while in w/o emulsions, water droplets are dispersed in oil. The result of an emulsion of oil and water mix is depended on the volume fraction of both phases and the kind of emulsifier utilized. You can actually tell the difference between the two by measuring the electrical conductivity of the emulsion. If there is no conductivity, it’s an w/o emulsion.

Both o/w and w/o emulsions have unique applications and chemical properties, and you can better choose the type you want to use if you know more about these differences. In this blog, we’ll provide some characteristics of o/w and w/o emulsions and describe some of the differences between the two.

Oil-in-Water Emulsions

Used in moisturizing products and food products such as milk, mayonnaise and vinaigrette, o/w emulsions contain a low oil concentration. They are mixable with water, non-greasy, non-occlusive and will absorb water. The dispersion medium in these emulsions is water; o/w emulsifiers keep oil drops packed in water.

Water-in-Oil Emulsions

These emulsions are utilized in products including butter, margarine, cold cream and cod liver oil and are especially useful in products designed for dry or sensitive skin. Common w/o emulsifiers are sorbitan stearate, polyglyceryl oleate, lecithin, sorbitan monooleate and lanolin. Sometimes referred to as an inverse emulsion, w/o emulsions mix more easily with oils and have a high oil concentration. Producing w/o emulsions is more difficult than developing their o/w emulsions.

Following are three additional differences between o/w and w/o emulsions:

1. Suspended vs. continuous phase

The biggest difference between o/w and w/o emulsions is which phase is suspended and which is continuous. Oil and water are normally immiscible, but with proper mixing and stability agents, a permanent mixture, or emulsion, can be achieved. Smaller droplet sizes will enhance the effectiveness of either system; this may translate to increased bioavailability in pharmaceutical products or extended shelf life in food/beverage products.

2. Type of product that can be created

The chemical nature of an o/w emulsion is distinct from that of a w/o emulsion; each is most effectively used in different products. O/w emulsions are the basis of water-based products; in the pharmaceutical industry, they can be found in creams like moisturizers and topical steroid products. In contrast, w/o emulsions make up oil-based products like sunscreen and most makeup.

3. How to achieve stability 

Stability is key when considering an emulsion synthesis technique; without it, the two phases will separate, and the product will have lower function. All emulsions require an emulsifier to assist with stability. O/w emulsions typically require more than one emulsifier, and they can be acquired separately or in a pre-mixed cocktail. In contrast, while w/o emulsions only require one emulsifier, there is a limited number from which to select because the hydrophilic balance must be in a narrow range. 

Emulsions, emulsifiers, homogenization and other terms can be confusing, but at BEE International, we can steer you in the right direction based on your specific business needs. Simply contact us to learn more!

High-pressure Homogenizers: Enhancing Oil Emulsification

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

high-pressure homogenizersYou might not think your daily life involves emulsions unless you work in a scientific field. However, emulsions and the products of which they are a part are found in a variety of industries, from pharmaceuticals and food manufacturing to metal processing and more. For example, milk and butter are emulsions found in daily life, and emulsions are responsible for enhancing both the textural and visual properties of medicated creams.

So what exactly is an emulsion? Basically, it’s a mixture of oily and watery liquids. There are two primary kinds of emulsions: oil suspended in water (o/w) and water suspended in oil (w/o). Both are inherently unstable and require force and functional chemicals, otherwise known as emulsifiers, to break apart oil droplets in order to mix with watery liquid. Following are three main differences between o/w and w/o emulsions: 

Suspended vs. continuous phase

Probably the most basic yet significant difference between o/w and w/o emulsions is which phase is suspended and which is continuous. Oil and water are normally immiscible, but a permanent mixture or emulsion can be achieved with the use of proper mixing and stability agents. In this case, smaller droplet sizes improve the effectiveness of either system, which may translate to increased bioavailability in pharmaceutical products or extended shelf-life in food/beverage products.

Type of product that can be created

O/w emulsions are the basis for water-based products; in the pharmaceutical industry, they can be found in creams like moisturizers and topical steroid products. W/o emulsions, though, form oil-based products such as sunscreen and many types of makeup.

Method used to achieve stability

All emulsions, whether w/o or o/w, require an emulsifier to assist with stability. O/w emulsions typically require more than one emulsifier, and they can be acquired separately or in a pre-mixed cocktail. In contrast, while w/o emulsions need one emulsifier, there are a limited number from which to select because the hydrophilic balance must be in a narrow range (3-6).

Again, 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, which work by forcing a sample through a narrow space and employing multiple forces, including turbulence and cavitation in addition to high pressure, are preferred. They not only impart high shear but also are able to reduce particle sizes much more efficiently than other blending and emulsification methods. In fact, high-pressure homogenizers can reduce droplet size to under one µm, produce more consistent emulsions and reduce creaming rate, thereby boosting the shelf-life of the emulsions.

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. Also, most high-pressure homogenizers currently manufactured offer reduced maintenance and reduced vibration and noise.

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.  

Benefits of BEE International

Rotor-Stator vs. High-Pressure Homogenizers: What You Need to Know

Posted by David Shechter on Mar 2, 2018 2:30:00 PM

high-pressure homogenizerIn a world where there are so many different types of products and so many versions of each, it’s easy to get confused. Sometimes I don’t want to spend five minutes in the toothpaste aisle looking through 35 different varieties of basically the same thing!

Even in the homogenization industry, there are multiple models: ultrasonic, rotor-stator bead mill, high-pressure and others. In this blog, I’ll detail rotor-stator and high-pressure homogenizers and list benefits and challenges of each.

Rotor-Stator Homogenizers

Rotor-stator homogenizers, also referred to as high-shear mixers or colloid mills, are designed to reduce particle size through hydraulic and mechanical shear and cavitation. Originally designed to make dispersions and emulsions, this type of homogenizer works through the rotation of a rotor inside a stator, which creates a suction effect. Mixing occurs when a sample is drawn in through one of the mixing heads while the blades rotate and is then expelled at a high velocity through an opening in the stator. The combination of high rpm from the rotor and exit through tiny slots allows the sample to be mechanically sheared into very small particles.

This type of homogenizer is best utilized for biological (plant and animal) tissue and processes liquid samples in the 0.01 ml-20-liter range. It is most often utilized in the chemical, cosmetic, pharmaceutical and food industries to create suspensions, emulsions, lyosols and other products through solid-liquid suspension, liquid-liquid emulsification and homogenization, particle size reduction, power-liquid dispersion and other applications.

Though high pressure-homogenizers employ high amounts of energy to form pressure differentials to homogenize ingredients, their rotor-stator counterparts manipulate ingredients though a shearing action. They generate minimal heat during operation and are able to homogenize fairly soft tissue. However, working with aerosols and foams can be difficult with this type of homogenizer.

High-pressure Homogenizers

Similar to liquid mixers, high-pressure homogenizers work by forcing cell suspensions through a very narrow channel under pressure. They use force (such as turbulence and cavitation) and high pressure to create a consistent and uniform sample. Primarily utilized for cell lysis or creating emulsions when large volumes are being processed, high-pressure homogenizers can be used for multiple types of bacteria, yeast and mycelia. Following are some of the many benefits high-pressure homogenizers provide:

  • Ability to process large volumes of liquid reproducibly and methodically. 
  • Consistency in composition of products.
  • Controlled turbulent flow and cavitation. 
  • Increased rate of dissolution.
  • Low risk of product contamination. 
  • Uniform particle size reduction.
  • Greater stability of final product.
  • Customizable forces to optimize results.
  • Consistent results in fewer passes.
  • Accommodation of a wide range of sample sizes.  
  • Decreased cost.

As you can see, high-pressure homogenizers offer enterprises a lot of benefits. However, it’s important to note that they can’t handle large particles or high-fiber materials and aren’t the most suitable for high-temperature materials. Plus, they can be large and very heavy.

Top Tips for Selecting a Tissue Homogenizer

Posted by David Shechter on Feb 27, 2018 2:30:00 PM

tissue homogenizerThe first thing many consumers point to when they hear the term “homogenization” is milk. August Gaulin received a patent for his homogenizer in 1899 and exhibited it to “treat” milk in 1900 at the World’s Fair in Paris.

Homogenization works by forcing the 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. In this blog, we’ll focus on tissue homogenization and what to consider when selecting a homogenizer to fit your specific business needs. 

In summary, tissue homogenization is a process employed to prepare tissue samples for further study, research or development. It involves the lysing (breaking apart) of cells to release their contents, from proteins and small molecules to DNA and RNA and more. The type of cell being lysed often dictates the homogenization device or technique that is used to complete the task. Homogenization is not only usually the simplest and safest approach to preparing such contents, it also is one of the quickest and most cost-effective methods. 

Techniques for Tissue Homogenization 

Knowing what techniques are best utilized for tissue homogenization can make choosing the right product a much easier proposition. These four techniques include chemical homogenization, freeze-thawing, and mechanical and ultrasonic homogenization. 

Chemical homogenization is best for small samples because the cost of materials used can be high for industrial-sized products. Freeze-thawing requires multiple cycles and a lot of time, and ultrasonic homogenization is only appropriate for tissues and molecules that aren’t affected by the temperature increase resulting from the high amount of heat it generates. The mechanical homogenization method can easily be scaled and offers time-efficient and consistent results. Overall, mechanical and ultrasonic homogenization are the two most commonly-used techniques.

High pressure homogenization allows for the forces of turbulence, cavitation, shear and impact to be used simultaneously to produce the best end result, even with delicate tissues. However, the lysate can be of higher quality and more even consistency when run through top-shelf equipment. 

Following is a list of things to consider when selecting a tissue homogenizer:

  • Toughness of tissue - Not all homogenizers can process more fibrous tissue, and those that can typically require a lengthy processing time.
  • Sample size and type – Large samples usually take more time to homogenize. Animal and plant tissues, yeast and bacteria typically require more rigorous methods of disruption.
  • Available components – Consider the product’s motor size, speed control and range, weight and dimensions and processing range.
  • Sample safety – The homogenizer used should be able to rapidly release the protein from its intracellular compartment into a buffer that isn’t harmful to the biological activity of the protein of interest. 
  • Uniformity of samples – The selected homogenizer should have the capability to quickly and safely produce consistent samples.


Before making a final decision on a homogenizer purchase, it’s a good idea to consult with businesses and/or laboratories with needs similar to yours. Another good idea is to request a demonstration from a couple manufacturers and compare the speed, cost and automation capabilities of the products

How Does RNA Extraction Homogenization Work? 

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

RNA extraction homogenizationMany people are familiar with the term “DNA,” which is the hereditary material in humans and almost all other organisms. Officially named deoxyribonucleic acid, it a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.

Not as well known outside the field of science is RNA or ribonucleic acid. RNA, a type of nucleic acid containing only one strand (DNA is primarily double-stranded), provides the link between the genetic information through protein synthesis. Procuring high-grade RNA, which is accomplished through a process called RNA extraction (or isolation), is the first step for a multitude of molecular techniques often utilized in gene expression including microarray analysis, real-time polymerase chain reaction (PCR), digital PCR, northern analysis and cDNA library construction.

RNA Extraction

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.

RNA extraction can be very challenging due to the difficulty of isolating RNA that is intact. This is in large part because of ribonuclease (RNase) enzymes found in cells, enzymes which are copious in the environment and can swiftly degrade RNA. Therefore, it’s vital that it be done cautiously and in a timely manner.

Homogenization – Organic RNA Extraction

The disruption of cell and tissue samples, often achieved by homogenization, is a required part of extracting RNAs and preventing their degradation. In fact, samples aren’t guarded from RNA degradation unless they are entirely homogenized. Although homogenization is especially functional for use with soft tissues, the method used should be based on the sort of cell or tissue. For instance, plant and animal tissues, yeast and bacteria typically require more exacting disruption methods. Either way, the sample or tissue should be kept frozen until it is ready to be homogenized.

Utilizing homogenization for RNA extraction is especially beneficial because it 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.
