If, on the other hand, your Petri dishes are made of plastic rather than glass, you can choose from a number of different sterilizing techniques.Sterilizing Glass Petri Dishes Turn on the electric hot-air sterilizing oven, and set the temperature to 160 degrees Celsius.Petri plates should be cleaned and rinsed carefully using a gentle cleaning solution, an abrasion-free cloth, antibacterial dish detergent, and warm water.

How to use agar plates/petri dishes?

Gather up any discarded petri dishes or culture plates that contain agar. To stop the proliferation of germs and lessen the likelihood of contamination, cultured agar plates and petri dishes should be covered with agar and left in their current state. 2. Prepare the Agar Plates and Petri Dishes for inoculation.

Which technique is used to sterilize plastic petri plates?

Sterilization is the process of killing or eliminating all germs capable of reproduction, and it may be performed through both physical and chemical ways. Sterilization can be accomplished by killing or removing all bacteria. However, the exposure of pre-wrapped petri dishes to either ionizing gamma radiation or electron beams is the method that has shown to be the most successful.
