The key to manufacturing competitive products and maintaining compliance is effective quality assurance and control in the highly regulated pharmaceutical industry. This is why microorganisms in liquids are quantified by the membrane filtration method. This method allows accurate quantification of bacteria, yeasts and molds when low counts in a high sample volume are anticipated. The method of transferring the membrane filter onto an agar medium is a critical step that can be a source of secondary contamination and lead to false-positive test results. Therefore, it is essential to reduce the risk of exogenous contamination entailed by the use of tweezers to transfer the membrane.

The Microsart ^® @filter units and Microsart ^® @media introduce an innovative concept for membrane transfer to agar media. Microsart ^® @media are agar media dishes for Microbial Limit Testing. They are pre-filled with different agar media types, sterile-packaged and ready to use together with Microsart ^® @filter filtration units. Moreover, the Microsart ^® @media features an innovative patented lid. This active lid enables touch-free transfer of the membrane, without using any tweezers. In addition, the convenient, liftable interior lid provides easy access to select colonies after incubation for further analysis
