Nasco B01613 Whirl-Pak Dry PolyProbe - 100 Probes

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. 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). To use, tear open the top of the bag; 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.
