Designed for surface sampling and effective in hard-to-reach areas, the 8 in. inch (20.3 cm) long probe consists of a polypropylene holder with detachable handle that is adhered to a durable polyurethane sponge that resists tearing and fraying. Probe is packaged in a sealed 24-oz. (710 ml) write-on bag and hydrated with 10 ml of HiCap™ Neutralizing Broth. Product is terminally gamma processed to guarantee sterility. Box contains five foil pouches with 20 probes each for a total of 100 probes. Bags are 9 in. L x 6 in. W (23 x 15 cm) with a thickness of 2.5 mils (.064 mm). Two-year shelf-life with ambient storage at 36°-86° F (2°-30° C). To use, tear open the top of the bag, squeeze out any excess neutralizing broth, swab the surface, insert the sponge back into the bag, and, while holding the sponge from the outside, unscrew the handle and discard. Drop the sponge into the bag, fold the top of the bag over three or more times, bend in the wire tabs to close, and send to a lab for testing.
