Petri Dishes are one of the most important products in a bacteriological laboratory. Our Petri Dishes are manufactured from high-grade polystyrene and have exceptional optical clarity for microscopic analysis as well as heat resistance for use with hot agar. They are available in both vented and non-vented design and the standard round design is supplemented by a square-profile dish. To enable parallel testing of a single sample using different agars, divided dishes with two or three compartments are available. The product range is completed by contact dishes and graduated germ count dishes which are used in hygiene monitoring including detection of microorganisms and testing the effectiveness of cleaning and disinfection on flat surfaces by means of contact cultures. Particularly in the pharmaceutical and food industries, analysis of germ count and germ species on surfaces is of major importance to detect and identify possible sources of infection.
