Hach® Presence/Absence Test, 50/Pack

The Hach Presence/Absence (P/A) test is an efficient and sensitive method for detecting total coliforms and E. coli in water, essential for the food processing industry. This EPA-approved test utilizes a pre-prepared liquid growth medium, allowing for the addition of a water sample and incubation for 24 to 48 hours. A color change signals the presence of total coliforms.

Designed for ease of use, this test requires minimal training and equipment, making it ideal for both laboratory and field applications in food safety and water quality monitoring. Its reliability is crucial for ensuring safe water in food preparation, environmental monitoring, and recreational water analysis, supporting compliance with health regulations in the food processing sector.
