A 50 x 9 mm petri dish design that is easily opened with one hand, yet closes to a tight seal by its unique double rim. Specimen samples are preserved until you are ready to analyze them. Humidity remains locked in. When loaded with a 47 mm absorbent pad, it is ideal for drying coated grids, removing water from grids that are supporting sections.
Available with or without absorbent pads. The dishes are sterilized by Gamma Irradiation
