Flow-through Chamber Accessory for a Lab Homogenizer
Lab homogenizers are often the instruments of choice when developing pilot-plant procedures to be scaled up to production line operations. Typically laboratory homogenizers are suspended over beakers or flasks containing samples to be processed by being drawn into the homogenizer generator for mixing, dispersing, emulsifying and similar treatment. Researchers can greatly extend the utility of…
Read MoreCleaning and Sterilizing Laboratory Homogenizers
As with medical and surgical instruments, laboratory homogenizers must be thoroughly cleaned and sterilized or disinfected after use to avoid contaminating subsequent samples. The complex designs of homogenizer rotor-stator generator teeth and slots provide an ideal setting to trap and hold sample particles. Here we present a suggested procedure that can be employed or modified…
Read MoreModular Homogenizer Shaft Tubes: Sealed or Non-Sealed?
Several decisions must be made when setting up a laboratory or pilot plant homogenizing exercise. Drive motor speed and power along with the rotor-stator generator assembly are among the top considerations. But don’t overlook the modular homogenizer drive shaft tube to which the stator is attached and which encases the rotor shaft. Drive shaft tubes…
Read MoreSelection Tips for Lab Homogenizer Generators
Rotor-Stator Generator Components Homogenizer generators – the working end of lab homogenizers that perform mixing, dispersing, emulsifying, and similar operations in research and pilot plant studies – are two-part assemblies. The first component is a rotating rotor attached by a rod to the drive motor. The rotor is a precisely machined tool with multiple sharply…
Read MoreUnderstanding Laboratory Homogenizers
A lab homogenizer is often the tool of choice for researchers in pilot plant labs to develop procedures aimed at achieving the most efficient method of processing samples that later can be applied to full-scale production lines. These versatile tools are fitted with what are called rotor-stator assemblies powered by a drive motor, much in…
Read MoreHow to Homogenize Vegetable Glycerin for E-Juice
This short video provides dramatic proof of the effect of temperature on the ability to homogenize vegetable glycerin for E-Juice. In it I demonstrate how glycerin at room temperature simply cannot be homogenized no matter how fast the homogenizer drive unit rotates. But after heating the glycerin to 60⁰C (140⁰F) it readily homogenizes in the…

Bob Wilcox talks about the importance of preheating vegetable glycerin before homogenizing, and demonstrates the difference.

You say you can’t emulsify the immiscible? Tsk. With the right equipment such as the CAT X120 hand held lab homogenizer oil, vinegar and water are quickly combined into (you guessed it) a salad dressing. I ought to know because I did it all by myself as shown in this 105-second video. Emulsifying is but…
Read MoreUse a Bottletop Burette for Accurate Liquid Measurement
A CAT post discussing the importance of temperature control in lab experiments noted the distinction between precision and accuracy. The same distinction applies to measuring liquid. Precision can be defined as dispensing the same amount of liquid time after time, suggesting that the equipment is precise. Accurate dispensing means that the correct amount of liquid…
