Petri Dishes (Borosilicate Glass)

These Petri Dishes come with beaded edges and can withstand repeated sterilization. The beaded edges provide good mechanical strength and also a serve the purpose of equally spacing the sidewalls of the bottom and cover, thus 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.
