HY-LiTE Liquid Test Pens for Free ATP (catalogue No. 130194) are disposable pens designed for semi-quantitative detection of free adenosine triphosphate (ATP) in liquid samples using HY-LiTE 2/2A luminometers. They allow rapid bioluminescent monitoring of biomass or cleanliness in rinse water, food & beverage process waters and other industrial liquids. The pens do not lyse cells and therefore measure only free ATP in solution.
HY-LiTE Liquid Test Pens for Free ATP (catalogue No. 130194) are ready-to-use sampling pens supplied by Merck for detecting free ATP in aqueous liquid samples utilizing a HY-LiTE 2/2A luminometer. ATP in the sample reacts with a luciferin/luciferase reagent in the luminometer to produce a bioluminescent signal proportional to ATP concentration. The Free ATP pens specifically detect ATP not contained within cells, providing information about soluble ATP levels in rinse waters and liquid process streams without cellular lysis.
Advantages
- Designed for rapid bioluminescent detection of free ATP in liquids.
- Used with HY-LiTE 2/2A luminometers for consistent performance.
- Does not lyse cells, measuring free ATP only and avoiding interference from cellular ATP.
- Suitable for process control, biomass monitoring and hygiene evaluation in food, beverage, water and industrial sectors.
- Disposable and easy-to-use format simplifies sampling and minimizes contamination risk.
