Membrane Filtration Sterility Test

The membrane filtration sterility test is the regulatory method of choice for filterable pharmaceutical products. The test is particularly suitable for samples containing preservative, bacteriostatic or fungistatic compounds, which inhibit microbial growth of potential contaminants. With membrane filtration, microorganisms are retained by a 0.45-micron pore size filter, and all inhibiting compounds are rinsed using a suitable rinse solution. Appropriate media, which are selected based upon their ability to support the growth of anaerobic and aerobic microorganisms, are then transferred to the membrane filters. A 14-day incubation period is required to obtain final test results.

“Steritest™ EZ devices are made by experts who are familiar with the practical obstacles and know exactly the users’ requirements – from practitioners for practitioners!

The big portfolio of different Merck Millipore Steritest™ EZ filtration devices enables us to conduct the tests for almost all kinds of products. There is always a solution, even if the product needs to be dissolved or diluted.”

-- Dr. Timo Krebsbach, Divison Manager Marketing & Sales, Labor L+S AG, Germany

Minimize False Positives

Closed Steritest™ EZ filtration units reduce the risk of false positive results to avoid costly investigation and possible batch loss. The entire testing process, from aliquoting to reading, is never exposed to the environment. There are no open containers or membrane manipulations, which could increase the risk of adventitious contamination.

Reduce False Negatives

Steritest™ EZ filtration units are the right answer to the danger that false negative results pose to patients. Through specific membranes, unique sealing technology and optimized device design, the unit allows efficient elimination of bacteriostatic, fungistatic, or bactericidal agents present in the pharmaceutical product formulation.
