Water Toxicity Tester HM-DXS

Product Overview:

The water toxicity tester is a new generation of biological acute toxicity analyzer for laboratory use. It is a toxicity detection system based on bioluminescent sensing technology. It performs rapid qualitative detection based on the changes in the luminous intensity of luminous bacteria during metabolism. Compared with traditional fish, fleas and other aquatic organisms as biological detection methods, the luminous bacteria method is simple, rapid, sensitive, adaptable, repeatable, accurate, low-cost and widely used. It is a rapid water toxicity detection instrument designed for environmental pollution, emergency accidents, security inspections and routine inspections. It can be used for the overall toxicity detection of heavy metals, poisons, nerve agents, pesticide preparations and other substances in water on site.

It complies with the national standard "GB/T15441-1995 Determination of acute toxicity of water quality-luminous bacteria method" and international standards (ISO11348-3).

Application industries:

Drinking water testing, emergency response-biological pollution, emergency response-toxic chemicals, toxic and hazardous waste, municipal drainage, rainwater testing, drilling fluid and mud testing, mining, wastewater, soil and water testing, industrial wastewater discharge testing, process water testing, seawater testing, medical/pharmaceutical product testing, food packaging testing, personal care products and household chemicals testing, sediment testing, rainwater runoff testing, solid sample testing, food processing water testing, etc.

Detection principle:

The handheld biological toxicity detector performs triple functions: toxicity testing, ATP testing and determination of microbial contamination; toxicity testing is performed using luminescent bacteria that exist in nature. This bacteria emits light during normal metabolism. If placed in a toxic environment, their cell respiration process is affected, resulting in a decrease in the amount of light emitted. The luminescence detector measures the amount of light emitted by the luminescent bacteria before and after exposure to the toxic environment, and the degree of reduction in the amount of light corresponds to the strength of the toxicity.
