USP 71 Sterility testing is widely used in both the medical device and pharmaceutical industries. As a USP test, it is the official procedure for testing the sterility of pharmaceutical products (USP 71). There are different methods to test the sterility of the products. 1,Direct Transfer-Immersion Sterility Testing 2,Membrane Filtrartion - open system 3,Membrane Filtrartion by Sterility test kits Method -a closed system Sterility Testing Method
The preferred method for sterility testing is the membrane filter method using a closed sterility test system, such as the new disposable sterility test system. Virtually all pharmaceutical containers and product types can be tested due to the wide range of sterility test units featuring different adapter types. We has developed the new Universal pump for sterility testing.

Under the positive pressure by peristaltic pump, the sample is transferred into the filtration units, then filtered and incubated with culture media, to examine that if there is any germ. The sample enters into the closed canister through the pipe by peristaltic pump, then filter out through the membrane which pore diameter is 0.45µm. If will be hold back above the membrane, and after rinsing the anti-microbial components, the closed canister is filled with media and used for incubation without any exposition to the environment. Put the closed canister in the appointed position at the specified temperature, and observe if there is any germ grows.
