Membrane-filtration sterility testing

The classical compendial sterility test method: filtering a sample through a membrane, incubating it in growth media for 14 days, and checking for microbial growth.

Where it's used

Sterility testing systems
Membrane-filtration pump systems, automated colony-detection platforms and rapid microbial detection instruments that confirm a parenteral product is free of viable microorganisms before release — a mandatory 14-day compendial test now increasingly compressed to hours or days by validated rapid alternative methods.
