PetriCell Dry™ is a revolutionary technology bringing innovation to the workhorse of microbiology, the agar-based Petri dish. Agar-based growth media needs to be refrigerated, and even so, it lasts only for about 30-90 days.

PetriCell Dry™ technology utilizes a proprietary cellulose-based, ready-to-use dry media, that performs like agar but remains active for at least 6 months with no refrigeration, even when containing supplements.
