Thermo Fisher, 101VR20, Sterilin™ Standard 90mm Petri Dishes

Sterilin™ Standard 90mm Petri Dishes is designed for culturing microorganisms on solid microbiological media. This configuration is a round, flat-bottom polystyrene dish with a 90 mm diameter, 16.1 mm height and three vents. The triple-vent design promotes gaseous exchange and is suited to short-term culture work where condensation and air exchange need to be balanced. The dish is manufactured from non-cytotoxic virgin polystyrene and has a mirror-finish surface that provides high optical quality for colony inspection. It is compatible with automatic plate pourers and is produced to the EN ISO 24998:2008 Petri-dish dimensional standard. This version is non-sterile and non-treated, so any sterility requirement must be addressed by the laboratory’s intended process rather than assumed from the supplied dish. Each pack contains 20 dishes, and a case contains 500. The shallow 90 mm format maximizes incubator space while providing the standard surface area used for routine agar culture, colony isolation and microbiological enumeration. The three-vent configuration distinguishes this version from single-vent and nonvented alternatives intended for different incubation requirements. Triple vents create three raised contact points between stacked dishes and allow air exchange around the culture surface. The clear polystyrene and mirror finish support visual inspection of colony morphology and counting without transferring the culture to a separate viewing vessel.
