Petri Dish Sets Ideal for Laboratory Use
Petri Dishes feature reinforced beaded edges that resist breakage and help in centering the bottom inside the cover. Dishes remain clear after repeated use in wet or dry sterilization cycles. Covers and bottoms are clearly marked and color coded for easy identification when sorting and assembling pairs. Covers have a fused-on, red ceramic enamel marking spot and the word Cover. Bottoms have a white ceramic enamel vertical arrow and the word Bottom. Choose from four different sizes.
