Petri dishes and absorbent pads, one-handed opening

A 50 x 9mm petri dish structure that is easily opened with one hand, yet closes to a tight seal by its remarkable double rim.  Tests are safeguarded until you are prepared to examine them. Humidity remains secured. When loaded with a 47mm absorbent pad, it is perfect for drying coated grids, expelling water from grids that are supporting sections.

Available with or without absorbent pads. The dishes are sterilised by Gamm Irradiation
