If sampling procedures require testing surfaces that are difficult to reach such as window ledges, light fixtures, air vent ducts, etc, the Nasco Sponge Pole will make the jobeasier, safer and more efficient. The adjustable aluminum pole is 6 feet long and extends to 10 feet. To use: autoclave the sponge holder and screw it on the end of the pole without touching the metal sponge clamp. Hydrate the sponge if necessary, squeeze out any excess liquid, and with a sterile gloved hand, insert the sponge in place on the end of the holder. Extend the pole to your required length, wipe the surface with the sponge, shorten the pole, remove sponge, place it in the Whirl-Pak® bag, and send to the lab for testing. Pole includes pack of 10 sterile sponges.
