Whirl-Pak B01403 Stand-Up Thio-Bags® - 10.1 oz. (300 ml) - Box of 100

A 300 mL stand-up Thio-Bag is designed for collecting, storing, and transporting water samples, especially in microbiological testing. It is commonly used in drinking water, wastewater, and environmental monitoring applications to test for bacteria such as coliforms or Legionella.

Each bag contains pre-dosed sodium thiosulfate, which neutralizes chlorine in water samples at the time of collection. This is critical because chlorine can kill microorganisms and lead to inaccurate test results if not neutralized immediately.

The stand-up design includes a gusseted bottom that expands when filled, allowing the bag to remain upright without a rack or holder. This makes sampling easier in the field and improves workflow efficiency during filling and labeling.

Yes, Thio-Bags are sterilized after manufacturing and individually sealed, ensuring they are free from contaminants. This makes them suitable for regulated testing environments where sample integrity is critical.

Compared to rigid containers, Thio-Bags are lightweight, unbreakable, and space-saving, reducing transport and storage costs. They also feature leak-proof seals, write-on labeling areas, and easy aseptic handling, making them more convenient for both lab and field sampling.
