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

At BEE International, our laboratory high-pressure homogenizers were designed to provide formulation scientists with more experimentation options and capabilities for emulsions, dispersions, cell rupture and liposomes. Plus, they offer a multitude of benefits and features, such as operating pressures of up to 45,000psi/3,100bar, 100 percent guaranteed scalability of results, lifetime training for new employees and students, CE and cGMP compliance and a one-year factory warranty.

Following is a list of the laboratory homogenizers we offer:

  • Nano DeBEE Laboratory Homogenizer - The smallest in our line of laboratory homogenizers, this cost-effective benchtop unit offers a reliable and consistent process for virtually any laboratory setting. With features including a state-of-the art reservoir for small volumes, an adjustable process pressure gauge, a heat exchanger and a back- pressure gauge, this is a popular choice for an entry-level laboratory homogenizer.
  • Micro DeBEE Laboratory Homogenizer – This air-operated, compact, benchtop unit is suitable for a broad range of applications, including cell disruption, particle size reduction, work with polymers and liposomes and the creation of nano and micro emulsions and dispersions. This model offers a bit more capacity and power than the Nano DeBEE Laboratory Homogenizer.
  • Mini DeBEE Laboratory Homogenizer - This cost-effective unit is suitable for both laboratory and research and development work as well as pilot plant and industrial production. It offers the same features as the Nano and Micro DeBEE Laboratory Homogenizers but with added capacity and power. Other features of this model include pressures up to 45,000 psi, 100 percent guaranteed scalability of results and a programmable logic controller a digital display.
