Whirl-PakŪ Thio-Bag Sampling Bags

Thio-Bags are specially made for sampling chlorinated water. Each contains nontoxic active sodium thiosulfate to neutralize chlorine at the time of sample collection. Bags feature a gusseted bottom so that, when filled, they stand up on their own! They’re an economical alternative to beakers and bottles. Each Thio-Bag also has a write-on strip for easy labeling. Transparent, 2.25-mil Bags are approved for microbiological sample collection for National Pollutant Discharge Elimination System (NPDES) compliance monitoring.
