Polystyrene petri dishes are suitable for culturing microorganisms on a 47mm diameter membrane filter. These disposable dishes have been designed for improved handling in the laboratory. Squared off edges provide a firm grip area for ease of opening with one hand. The raised ridge on both top and bottom allows dishes to be stacked without sliding off. The snug fit lid ensures neither the absorbant pad nor agar will dry out during incubation yielding a false result.

PD-2 dish is preloaded with an absorbant cellulose pad which absorbs 1.8 - 2.2 mL.
Sterilized by gamma irradiation. Certificate of compliance available upon request.
