Whirl-Pak B01254 Thio-Bags® - 10.1 oz. (300 ml) - Box of 100

The Whirl-Pak B01254 Thio-Bag is designed for collecting and transporting water samples for microbiological testing, especially in chlorinated environments like drinking water systems, pools, and wastewater facilities. It ensures sample integrity for tests such as coliform and bacterial analysis.

Each bag contains a pre-measured sodium thiosulfate tablet (typically 25 mg) that neutralizes chlorine at the time of sampling. This prevents chlorine from killing bacteria in the sample, ensuring accurate lab results.

Yes, these bags are post-manufacturing sterilized, making them ready for immediate use without additional preparation. This reduces contamination risk and helps maintain compliance with regulatory testing standards.

This model features a 300 mL fill capacity, durable 2.5 mil polyethylene construction, and dimensions of approximately 4.5" × 9". It also includes a write-on strip for labeling and is supplied in a box of 100 bags.

Thio-Bags are lightweight, leak-resistant, and space-saving, making them easier to transport and dispose of. They also reduce storage costs and simplify sampling workflows while maintaining sterile conditions and reliable results.
