Whirl-Pak® Thio-Bag® Dosed Sterile Sample Bags provide a reliable, sterile shipping and storage solution for water sampling and bacterial analysis. Each bag contains a nontoxic, nonnutritive tablet containing active sodium thiosulfate to neutralize chlorine during collection to ensure accurate test results. Perfect for use in municipalities, swimming pools, wastewater treatment, and other water quality testing applications, these flexible, leak-proof bags offer a sustainable alternative to rigid containers. Specifically designed for sampling chlorinated water, the bags will also accommodate solids, semi-solids, and other liquids to test for fecal coliforms, legionella, and other bacteria. The opening Tyvek® pull tabs are perpendicular to the bag's opening, keeping hands away for a safe, aseptic collection technique each time. To use, label the bag using the convenient write-on strip, tear off the top along the perforation, use the pull tabs to open the bag, then place the sample in the bag. To close, hold the bag by the tabs and whirl 3 to 4 times to create a seal, or fold the tab over tightly 3 to 4 times to close, then bend in the wire tabs or bring the two wire ends together and twist to close. The continuous perimeter seal ensures satisfaction during sample collection, and the trusted, puncture-proof closure tabs provide a sturdy grip and secure, leakproof closure. The capacity is measured when the bag is closed and the tab is folded over three times (volume and dimensions are approximate, ±5%). The shelf life is 5 years from the sterilization date on the sterility confirmation documentation.
