PETRI DISH 100X15MM 500/CS
Top and bottom edges are squared off (not rounded) to provide a firm, sure grip
Bottom is flat so medium spreads evenly over the entire dish bottom
Three venting ribs built into the underside of the lid prevent buildup of condensation that would drip onto the media
Lid skirt is flared just enough so that it can be replaced quickly after streaking
Lid fits loosely enough to provide air exchange, yet is tight enough to reduce risk of aerial contamination
Place lid upside down on dish to close off dish from outside environment
