EPA-Approved Bags for Potable Water Collection
Thio-Bags are specially made for sampling chlorinated water. Each Bag 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 econimical alternative to beakers and bottles. Each Thio-Bag also has a write-on strip for easy labeling.
