Coli-Count Swab Test Kit, 25pk

These sterile kits are used for testing surfaces, even in hard to clean areas.  They consist of a sampler and swab in buffer. The sampler incorporates a plastic tab supporting a filter bonded to an asborbant pad containing a dehydrated nutrient medium.  The filter surface is grid-marked to permit counting of colonies.  Each sampler absorbs 1 ml of sample.
