Whirl-Pak Stand-Up Thio-Bags® (Nasco)

Whirl-Pak Stand-Up Thio-Bags® Sampling Bags

Specially designed for sampling chlorinated water, the Whirl-Pak® Thio-Bag® is economical and convenient to use. This single use, sterilized, lightweight, unbreakable container is always ready for immediate use.

Used by many states and EPA approved, this strong transparent bag holds a nontoxic, nonnutritive tablet containing 25 mg of active sodium thiosulfate to neutralize chlorine at the time of collection. As an added feature, Thio-Bags® have a convenient Write-On Strip.

The Whirl-Pak® Stand-Up Bag makes sample handling and testing much easier because it gives users the ability to perform important laboratory functions with both hands, because the bag will stand completely by itself. No rack or other holder is needed to keep the bag upright. When the sample is placed inside, the special gusseted bottom flattens out, allowing the bag to stand up on its own. It works just like a beaker or bottle, however, it costs less, is sterilized, won't break, and uses only a fraction of storage space as the other containers.

Capacity is measured in fluid ounces when the bag is closed and tab is folded over three times. Volume and dimensions are approximate; bags should not be used at temperatures above 180° F (82° C). Bags can be frozen to any temperature, even liquid nitrogen temperatures down to -346° F (-210° C) - careful handling required after freezing. All bags are sterilized after manufacturing.

Shelf life from Sterilization date found on the Sterility Documentation: 5 years
