Sample Bags for Coliform Testing

Sample Bags for Coliform Testing

Developed over 50 years ago, and made in the USA, Whirl-Pak bags were the first sterile sample bags on the market. They were designed to provide milk haulers with a container for collecting samples of bulk produced milk. Whirl-Pak® bags made possible the universal sample system, which means that a single sample can be used for all tests required for quality control, product content, and legal compliance.

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.
