Our unique gripping ring feature on 60mm, 70mm and 100mm dishes offers a ridged, protruding edge on the dish base for easier handling and to prevent accidental lid lift-off. Molded spacers on the base of the dishes allow heat and gas exchange between stacked units and speed up acclimation in teh incubator. Dishes are supplied with vented lids and are sterilized by gamma irradiation.

Dishes are packaged in easy-to-open sealed plastic sleeves. Every package is printed with lot number for quality traceablity.
