How to Clean Lab Homogenizer Dispersing Tools – Video

Laboratory homogenizers are used in a variety of application, among which are included mixing, emulsifying and dispersing lab samples. Whatever the application one point remains constant: a lab homogenizer must be cleaned before it is used to perform another processing function. This avoids the potential of cross-contamination between samples being processed.

Cleaning is particularly critical because lab homogenizer dispersing tools have complex configurations consisting of the rotor and stator assembly (collectively the generator), the generator shaft, the shaft tube, spacers and bushings. Even if used with like samples dispersing tools should be cleaned regularly – think after a shift or at the end of the day – to avoid samples hardening or becoming moldy inside the assembly.

Cleaning homogenizer dispersion tools is a straightforward operation requiring minimal effort to disassemble, clean and reassemble the various components. This is accomplished by using the universal socket wrench and rotor key shipped with drive motors or separately ordered. A test tube brush is extremely useful to clean the interior of the shaft tube. Soap and water followed by a rinsing operation accomplishes the basic task. For particularly stubborn contaminants or where extra care is needed to avoid potential sample contamination we suggest taking a look at our post on sterilizing a lab homogenizer.

But back to the subject of this post, I’ve starred in yet another video presentation on how to disassemble, clean and reassemble a T-17 dispersing tool used with CAT lab homogenizers. The same steps apply to any of our many homogenizer dispersing tools. When you view it, please make note that certain components are removed and replaced clockwise or counterclockwise. That means “righty tighty lefty loosy” does not always apply. The video is short, so grab a coffee or soda and watch the Homogenizer Cleaning Video.

There are a variety of CAT modular homogenizer drives and dispersing tools to help you develop processes that can be scaled to production line operations. You’ll find examples in our homogenizer blog posts. If you don’t find the answer to your processing needs send us your question or complete our Homogenizer Questionnaire.
