Description

A homogenizer is a piece of laboratory or industrial equipment used for the homogenization of various types of material, such as tissue, plant, food, soil, and many others. ... The mortar and pestle, already used for thousands of years, is a standard tool even in modern laboratories.

What is an ultrasonic homogenizer used for?
Ultrasonic homogenizers are commonly used for processing small samples that are in suspension and don't require any pre-grinding or cutting. They can be used for cell lysis, emulsion preparation, for mixing and dissolving purposes, and to accelerate chemical reactions.

Ultrasonic homogenizers, or sonicators, are used in cell lysis and particle size reduction applications. This equipment uses pulsed, high frequency sound waves to disrupt particles through a phenomenon called cavitation. Cavitation occurs when a rapid pressure change causes “liquid-free zones” or cavities in a liquid. As these cavities collapse, shock waves are generated throughout the liquid, which causes the cells or large particles to rupture.

homogenization, process of reducing a substance, such as the fat globules in milk, to extremely small particles and distributing it uniformly throughout a fluid, such as milk. When milk is properly homogenized, the cream will not rise to the top. The process involves forcing the milk through small openings under high pressure, thus breaking up the fat globules.

Cream and other food products, such as peanut butter, may be homogenized to produce a stable emulsion—one in which fats or oils will not separate from other elements. A similar process is used in the manufacture of some cosmetics and pharmaceutical products.

Uses and Shortcomings of Ultrasonic Homogenizers

Ultrasonic homogenizers are commonly used for processing small samples that are in suspension and don’t require any pre-grinding or cutting. They can be used for cell lysis, emulsion preparation, for mixing and dissolving purposes, and to accelerate chemical reactions.

Limitations of ultrasonic homogenizers include the generation of heat, which may be detrimental to temperature-sensitive samples. Sonicators can also shear DNA, which may or may not be desirable, depending on your application.

Ultrasonic homogenizers make a very loud, “hissing” noise and the appropriate personal protective equipment must be worn by operators and lab technicians.

Ultrasonic homogenizers do not lyse all cells equally. The cell walls of plant cells are far more resistant to sonication than cell membranes. Lastly, there is a possibility of cross contamination, as the sonicator probe comes into direct contact with the samples.
