The 100mL capacity sterile containers with sodium thiosulfate tablets are used to test for the presence of coliform bacteria, microbiological contaminants in drinking water. Manufactured from pure polypropylene in a sterile environment and sterile-by-process. The EPA fill line of 100mL ± 2.5% makes it easy to use. A sodium thiosulfate tablet has been added to each container thus saving lab prep time and expense. Leak tight when sealed properly. An added benefit is the tie-down to protect from accidental opening and also serves as a custody seal. Sample label and instructions for use are supplied with each. A low cost, convenient product which meets EPA requirements.
