• Plus 1 sterilization, post-manufacturing sterilization: Increased sample integrity, perforated closure to maintain sterility
• Thiosulfate tablet in the bag, saving technician's time

The job of collecting water samples is easier with the Whirl-Pak® Stand-Up Thio-Bag®. A special gusset on the bottom of the bag flattens out when water is put in the bag, allowing it to stand up completely by itself. No rack or other holder is needed to keep the bag upright. Forget washing and sterilizing glass bottles and disposing of expensive vials. Sterile and unbreakable, these bags will save time and money whether working in the lab or in the field. Each bag contains 25 mg of active sodium thiosulfate to neutralize chlorine in the sample.

Shelf life from sterilization date found on the sterility documentation: 2 years from sterilized date found on your sterility confirmation.
