Santa Maria, California, Jan. 5, 2015 (GLOBE NEWSWIRE) -- Hardy Diagnostics, an FDA licensed and ISO certified biomedical manufacturer, is pleased to announce the release of Compact Dry, a simple method for cultivating and counting common food- borne microorganisms.

Compact Dry is a self-contained device containing a membrane matrix saturated with a culture medium and a gelling agent, and then dried.  A diluted food sample (1mL) is added to the center of the device, which diffuses automatically and evenly throughout the plate.  The device is then incubated, after which a technician counts the colonies

Compact Dry is available in many formats:  Total Viable Count (TC), E. coli & Coliforms Count (EC), Coliforms Count (CF), S. aureus (X-SA), Yeast and Mold Count (YM), Bacillus cereus (X-BC), V. parahaemolyticus (VP), Salmonella (SL) and Listeria (LS).  The devices are simple to inoculate, have a long shelf life (18 months) except SL (16 months) and LS (10 months), can be stored at room temperature, have large write-on area, and can be easily stacked. If further testing or sub-culturing is needed, the lid is easily removed and colonies can be picked with ease. The Compact Dry has earned multiple performance certifications, such as AOAC and MicroVal.
