Microsart @media, agar media dishes for microbial limits testing, are prepared to satisfy U.S. Pharmacopeia (Chapter <61>) and European Pharmacopeia (Chapter 2.6.12) requirements. They are prefilled with various agar media types, such as tryptic soy agar or R2A agar. They are sterile packaged and ready to use in combination with Microsart @filter units. They also feature a lid that allows touch-free transfer of the filter membrane onto the media. Touch-free membrane transfer is meant to eliminate membrane manipulation and handling, reducing a source of secondary contamination. The liftable lid is designed to facilitate access to the colonies after incubation.
