Petridish TARSON Triple Vent Radiation Sterile: Vented dishes have elevated lid which allows for good gas exchange and encourage evaporation. This design is useful when the poured dishes are to be used as soon as possible. The design of the dish maintains sterility because the particles would have to go up and over the dish wall to get inside which is very rare in normal airflow. PS confirming to US FDA 21 CFR.
