How to Disassemble, Clean, and Reassemble the G40 Rotor-Stator Shaft

In this video, we demonstrate the precise steps you’ll need to take after every use of your G40 rotor/stator shaft assembly. Cleaning immediately after every use is crucial to prevent potential cross contamination of subsequent samples or procedures. Given the exceptionally fine stator slots and rotor geometries, fine particles can become lodged in these precision devices.

Particles or sample residues could contribute to future sample contamination, or even corrosion of the homogenizer shaft/generator assembly. Therefore, we strongly recommend running the assembly in an appropriate solvent, after every use. This is followed by immersion in sterile water, then followed by disassembly, cleaning, and reassembly.

In this video, we demonstrate how to take the components of the homogenizer shaft/generator assembly apart, allowing for thorough cleaning of all parts. We then show you how to reassemble your rotor/stator assembly so it’s ready for the next use.
