Video: How to Change Homogenizer Generators

CAT Scientific homogenizer generators are available in multiple configurations and are selected based largely on the viscosity of the media being dispersed or the objective of the homogenizing action.  To satisfy these requirements we offer a broad range of dispersing tool options in terms of length, diameter and rotor-stator configuration. Many of our homogenizer posts…

Specifying a High Viscosity Stirrer

Labs and pilot plants mixing high viscosity materials place special performance requirements on their overhead stirrers.  Viscosity of a fluid, as defined by Wikipedia, “is a measure of its resistance to gradual deformation by shear stress or tensile stress.”  It is due to friction between particles in a fluid that move at different velocities. As…

Achieve Superfine Disintegration with a High-Speed Homogenizer

Superfine disintegration in samples from 0.l ml to 2 liters in volume is achieved by using high-speed lab homogenizers such as the X360 offered by CAT Scientific. With a design speed of 45,000 RPM the 350-watt drive motor can be mated to rotor-stator generators in 6 sizes from 6 to 40mm in diameter and Teflon…

Overhead Stirrer Operation Options

Multiple experiments or pilot plant trials utilizing overhead stirrers as part of the mixing procedures are greatly simplified when overhead mixers can be individually controlled via a computer program.  This sure beats lab assistants moving up and down aisles to check on the performance of each piece of equipment. A Windows-based PC program with comprehensive…

A Brief on Lab Homogenizer Applications

The term “homogenizing” covers a variety of processes that simply defined means blending materials that may or may not be compatible.  A common example is homogenized milk.  It is homogenized to provide even consistency by dispersing the heavier cream into the more liquid milk to and prevent separation during storage. A much broader definition relates…
