Description

Prefiltration homogenizing cup

Technical Field

The utility model relates to the field of homogenizing cups, in particular to a prefiltering homogenizing cup.

Background

Existing capsules and tablets are prepared into suspension by homogenization by using a homogenizer for membrane filtration microbiological detection. However, some capsules and tablets have more insoluble components, and the insoluble components adhere to the surface of the filter membrane after membrane filtration, which affects cultivation and observation. At present, a method of settling by standing or prefiltering with a filter and then membrane filtration is adopted to solve the problem. The settling time is not well controlled, the settling effect is not obvious due to short settling time, and microorganisms can be settled along with the settling after long settling time; prefiltering requires the reuse of filters for operation and greatly increases the risk of exogenous contamination.
