Petri Dishes

Transparent polystyrene (PS). The ventilated plates have 8 vents, 4 of which are functional for the passage of air and 4 additional to guarantee maximum stability of the lid. Improvements have been adopted to guarantee maximum stability of the dishes once stacked, these include:

• Increased plastic thickness for greater resistance to deformation
  under thermal and mechanical stress
• 4 vents that help center the plate and lid
• oversized rings on the edge of the lid and on the bottom of the plate
  to further improve its stability
• sterilized or clean as produced
