Wholesale of Handheld Biological Toxicity Testers

Product Introduction:

Handheld biotoxicity detector 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 national standard luminescent bacteria method is simple, fast, sensitive, adaptable, repeatable, accurate, low-cost, and widely used. It is a water toxicity rapid detection instrument designed for environmental pollution, emergency accidents, security checks, and routine testing purposes, and can be used for overall toxicity detection of heavy metals, toxic agents, nerve agents, pesticide formulations, and other substances in water on site.

The instrument complies with national standardsGB/T15441-1995 Determination of Acute Toxicity of Water Quality - Luminescent Bacteria Method "and International Standard (ISO11348-3).

Application industry:

widely used inDrinking water testing and emergency response-Biological pollution, emergency response - toxic chemicals, toxic and hazardous waste, municipal drainage, rainwater testing, drilling fluid and mud testing, mining industry, soil and water body testing, industrial wastewater discharge testing, process water testing, seawater testing, medical/pharmaceutical product testing, food packaging testing, personal protective equipment and household chemical testing, sediment testing, rainwater runoff testing, solid sample testing, food processing water testing, etc.

Detection principle:

The handheld biotoxicity detector performs three functions: toxicity testingATP detection and determination of microbial contamination; 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 HD-DXS luminescent 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.
