Sample Bags for Coliform Testing
Whirl-Pak® sample bags are a co-extrusion of low-density and linear low-density, virgin polyethylene, giving the bags two important characteristics:
- Exceptionally clear film - easy to see through
- Superior strength - unbreakable sample container
They may be used for taking samples of liquids, semi-solids, or solids. Whirl-Pak® bags are patented under Patent No. 2,973,131 and other patents pending. The film thickness varies from 2.25 mils (0.057 mm) to 4.0 mils (0.102 mm), depending on size and style. Because of the high-quality blended polyethylene, a high mil thickness is not required to achieve optimum strength.
The amount of chlorine neutralization by the tablet depends on the pH of the water. The tablet contains 10 mg of active sodium thiosulfate and can neutralize up to 10 mg chlorine.
