2 Sections Plastic Petri Dish

Petri dish, 
Material: plastic PS
round, 2 sections petri dish, 90mm

Flat, clear dishes with beaded edges withstand repeated sterilization (wet or dry)

These flat, clear dishes will withstand repeated sterilization (wet or dry). The edges are beaded to provide greater mechanical strength. The bead also provides a means to equally space the side walls of the bottom and cover, thereby reducing the capillary action of condensed moisture on the sides. They are not affected chemically or thermally by any of the methods 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.

What is Petri dishes?
A petri dish is a type of glass or plastic shallow round dish with a close fitting lid which is a vital tool in scientific laboratories. The uses for this piece of equipment are varied, but it is most well known for holding a culture medium upon which cells, bacteria, and viruses can be grown and studied. Most major scientific breakthroughs have been greatly assisted by the use of petri dishes whether they involve the structure of a virus or the ability to clone meat.
