Water Sampling Bags
Sterile, space-saving stand-up bags with a pre-dosed sodium thiosulfate tablet, designed to neutralize residual chlorine when collecting water samples for microbiological analysis.

Neutralize chlorine at the point of collection.
Residual chlorine can continue to act on microorganisms after a sample has been collected. A pre-dosed sodium thiosulfate tablet helps neutralize chlorine so the sample better reflects the microbiological condition at the collection point.
- Pre-dosed neutralizer — no separate reagent preparation
- Flexible stand-up format for convenient filling and reduced storage space
- Wire closure and write-on identification area for secure transport and traceability
- Suitable for drinking water, pools, environmental and process-water sampling, subject to the laboratory method
