The HardyCHROM™ plates use optically clear, heavy-duty polystyrene mono plates for distortion-free viewing and reduced breakage during shipping. Receive your pack in a "breathable" sleeve of 10 plates per bag that prevents the buildup of condensation and excess moisture. Hardy mono plates feature raised rings for stacking ability and prevent sliding.

See the Instructions for Use (IFU) below (under Technical Information) for the complete procedure with color photos.

This media is to be stored and incubated in the dark. If you have a light in your refrigerator, incubator, or you leave the media exposed to light on the benchtop, we offer free Blok-Boxes. Blok-Box is a reusable cardboard box that holds one sleeve of ten Petri plates.
