Nasco Whirl-PakŪ Water Collection Bags4 oz./100 ml. Standard Whirl-PakŪ Thio-BagŪ

Specially designed for sampling chlorinated water, the Whirl-PakŪ Thio-BagŪ is economical and convenient to use. These single use, sterilized, lightweight, unbreakable EPA approved containers are always ready for immediate use. 

Each 100 ml or 300 ml bag holds  nontoxic, nonnutritive tablets containing 10 mg or 30 mg of active sodium thiosulfate to neutralize chlorine at the time of collection. All Thio-BagsŪ incorporate a convenient write-on strip.

The bags are also available in a stand-up version, which incorporates a special gusset on the bottom of the bag that flattens when filled, allowing the bags to stand up on their own.

All bags are packaged 100 per box and are sterilized as a unit of 100.
