Dishes withstand repeated wet or dry sterilization|Easy sortingtops marked in blue, bottoms marked in white|These flat, clear culture dishes will withstand repeated sterilization(wet or dry). The edges are beaded to provide greater mechanial strength. The bead also provides equal spacing from the walls of the bottom and cover, reducing the capillary action of condensed moisture on the sides. These dishes are not affected chemically or thermally by any of the mehtods commonly employed in laboratories where sterilization is a major factor in routine or in specialized work. The covered dish is not airtight. The tops are marked in blue enamel and the bottoms in white enamel to make sorting easier. Bottoms also have a triangular, enamel reference point for serial dilutions.
