These sterile and disposable polystyrene (PS)dishes are ideal for culturing fungi, bacteria, and other microorganisms. Dishes work well in robotic dispensers due to flatness and uniform height. Models 14007-10 and -11 are square in shape. Models 14007-03 and -05 are 5-mm deeper and models 14007-04 and -14 are 10-mm deeper than standard dish depths to accommodate longer culture periods. Sterilized by gamma irradiation.
