Sterile polyethylene bags are designed for sampling any potable water supply. Each bag includes nontoxic, non-nutritive tablets containing 10mg of active sodium thiosulfate. The 100mL size bag for single test use includes one tablet and features 4oz. and 100mL indication lines. The 300mL bag includes three tablets and is suitable for multiple tests. Puncture-proof tab bag closures are labeled “NASCO Thio-Bag” for easy identification. White write-on strip accepts pen, pencil, and felt-tip marker.
Stand-up bags (11216-922, 11216-924) feature a gusset on the bottom that flattens out when the sample is placed inside, allowing the bag to stand up completely by itself without the need for racks or special holders.
Double grid plastic coated carrying racks have a second grid approximately 2.5cm (1") below the top to keep bags upright. Rack 11216-762 provides 15 compartments for 100mL bags. Rack 11216-786 provides 12 compartments for 300mL bags.
