BOX OF 100 UNITS

Accurate water sampling starts at collection.

These sterile sampling bags with pre-dosed sodium thiosulfate are designed for reliable collection, storage, and transport of water samples for microbiological testing. The integrated thiosulfate neutralizes residual chlorine at the point of collection, helping preserve sample integrity and ensure accurate results.

The compact 100 mL format is ideal for routine monitoring and regulatory sampling where smaller volumes are required.
