Luminescent bacteria biotoxicity detector

Luminescent bacteria biotoxicity detector

It is a new generation of acute toxicity testing for laboratory useYi is a toxicity detection system based on biological fluorescence sensing technology, which qualitatively detects the changes in luminescence intensity of luminescent bacteria during metabolism. Compared with traditional biological detection methods such as fish, fleas, and other aquatic organisms, the luminescent bacteria method is simple, fast, sensitive, adaptable, repeatable, accurate, low-cost, and widely used. It is a water quality toxicity rapid detection instrument designed for environmental pollution, emergency accidents, security checks, and routine testing purposes. It can be used for overall toxicity detection of heavy metals, toxins, nerve agents, pesticide formulations, and other substances in water on site

execution standard

GB/T15441-1995 "Determination of Acute Toxicity of Water Quality - Luminescent Bacterial Method"

ISO11348-3-2007 "Water Quality Determination of the inhibitory effect of water samples on the light emission of Vibrio species

GB/T 36004-2018 "Test Method for Cleaning and Disinfection Effectiveness of Food Contact Surfaces - Adenosine Triphosphate Bioluminescence Method"

Detection Principle

Perform dual functions: toxicity testing and ATP; Conduct toxicity testing using luminescent bacteria found in nature, which emit light during normal metabolic processes. If placed in a toxic environment, their cellular respiration process is affected, resulting in a decrease in luminescence. The GR-5050 luminescence detector measures the luminescence of luminescent bacteria before and after exposure to toxic environments, and the degree of reduction in luminescence corresponds to the strength of toxicity.The detection results can be compared with the standard toxic substances HgCl2 or zinc sulfate heptahydrate to determine the corresponding toxicity level.
