An Introduction to Modular Laboratory Homogenizer Systems

Homogenizers as the name suggests perform a homogenizing function. A common example is homogenized milk, a function performed to avoid separation of cream from milk.  This is done with production-line homogenizers.  In R&D labs and for initial pilot plant operations lab homogenizers are put into play.  This post introduces you to modular laboratory homogenizer systems…

Homogenizer Options: Choosing What’s Right for Your Specific Needs

There are a dizzying assortment of choices when it comes to choosing the appropriate homogenizer or homogenizers for your laboratory or production facility. Mixing and processing tasks can often be accomplished with tools as simple as standard magnetic stir plates. But many applications will require more sophisticated mixing technology. This is especially true in the…

Principles of Rotor Stator Homogenization

Since prehistory, mankind has devised clever ways to crush — and blend — various substances. From simple mortar and pestle combinations to water-driven gristmills, the benefits of grinding and mixing have long been obvious. The goal is always the same: to render large, inconsistently sized particles — from cells, to grains, to stones — into…

Compressed Air Lab Homogenizers for Hazardous Areas

Certain laboratory environments can contain flammable vapors or gases that could be ignited by stray electrical sparks.  Equipment used in such labs – such as explosion-proof refrigerators and freezers  as well as explosion-proof electrical fixtures – require special design characteristics.  The same applies electrically powered benchtop lab instruments such as lab homogenizers.  The CAT Scientific…

Small Sample Emulsifying with a Lab Homogenizer

How to Emulsify Small Samples With a Lab Homogenizer The old saying “oil and water don’t mix” does not hold true all the time.  While it is true that oil and vinegar in the salad dressing cruet will separate on standing, homogenized milk holds the cream in suspension on the supermarket shelf and in your…

When to use Sealed and Non-Sealed Homogenizer Shafts

Laboratory homogenizer shaft assemblies have a number of components, all designed to work together to accomplish homogenizing, emulsifying, mixing, cell disruption, and similar processing.   The work performed governs the selection of the homogenizer generator, specifically choosing the correct rotor-stator configuration.  This includes the size (diameter) and the length of the shaft assembly. For certain homogenizing…

A Quick Guide to Lab Homogenizers

Laboratory homogenizers are among the most versatile tools in research.  Lab homogenizers are virtually indispensible because they help scientists efficiently evaluate various approaches to mixing, dispersing, cell disrupting, emulsifying, particle reduction and similar exercises.  The objective is developing efficient homogenizing procedures that can be scaled to commercial production levels. Selecting a Homogenizer Mixer Homogenizer mixers…

Cleaning Tips for CAT Scientific Homogenizers

You’ve made a substantial investment in your rotor/stator homogenizer or emulsifier, so it is important that you maintain it to the highest standards, including cleaning the shafts and generator assemblies to avoid potential cross-contamination when processing different samples. Cleaning is especially critical because of the complex shapes of generators – many of which have extremely…
