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.

Non Vented Radiation Sterile: Non vented dishes have lid which fits flatly on the base resulting in less potential for external contamination and significantly less evaporation rate. PS confirming to US FDA 21 CFR.

Aseptic Petridish: These are manufactured in clean room under aseptic conditions which ensures no contamination. Extremely high sterility assurance SAL 10-3_ They are particulate free, free of chemical residues, which usually results in false negative readings. Eliminates discolouration and stress caused by radiation sterilization. PS confi rmi ng to US FDA 21 CFR.

Petridish triple vent extra depth radiation sterile: Extra depth is advantageous in plant tissue cu lture. PS confirming to US FDA 21 CFR.
