Anhydrous nutrient plates for simple microbiological analysis of solutions and dry matter.

CompactDry™ plates are suitable for detection and enumeration of microorganisms from foods and feeds, cosmetics and pharmaceutical samples, as well as for hygiene monitoring and contamination control in food-producing areas. Due to the chromogenic additives, colonies depict specific colouring, making them easy to interpret.

CompactDry™ plates are easy and safe to handle. Due to storage at room temperature, they may be used even on site. One millilitre of the sample to be analysed is applied onto the sterile plate surface, spreading itself evenly over the plate during rehydration of the medium. Dry sample matter is homogenised and solubilised using the CompactDry™ Dilution Rack (Art. No. 4823.1) prior to plate inoculation.

Compact Dry PA is a standard culture medium containing nutrient agar for the detection of the genus Pseudomonas aeruginosa.Due to the redox indicator tetrazolium salt, the bacterial colonies show a red colouration. Differentiation from other pseudomonads is achieved by the formation of a coloured halo around the colony.Pseudomonas aeruginosa grows as a red colony with a green-yellowish halo.
