Biological toxicity tester

The Water Quality Biological Toxicity Tester is a new-generation biological acute toxicity analyzer designed for laboratory use. It is a toxicity detection system based on biological fluorescence sensing technology, which performs qualitative and quantitative detection based on changes in the luminescence intensity of luminescent bacteria during metabolism. Compared to traditional biological testing methods using fish, daphnia, and other aquatic organisms, the luminescent bacteria method is simple, rapid, sensitive, adaptable, reproducible, precise, cost-effective, and versatile. This water quality toxicity rapid testing instrument is designed for purposes such as environmental pollution monitoring, emergency response, security inspections, and routine testing, and can be used for on-site testing of the overall toxicity of substances such as heavy metals, toxic agents, nerve agents, and pesticide formulations in water. Complies with the national standard “GB/T15441-1995 Determination of Acute Toxicity of Water Quality—Luminescent Bacteria Method” and the international standard (ISO 11348-3).

The biological toxicity tester is applied to drinking water testing, emergency response to biological contamination, emergency response to toxic chemicals, toxic and hazardous waste, municipal drainage, rainwater testing, drilling fluid and mud testing, mining industry, wastewater, soil and water body testing, industrial wastewater discharge testing, process water testing, seawater testing, medical/ pharmaceutical product testing, food packaging testing, personal care products and household chemical testing, sediment testing, rainwater runoff testing, solid sample testing, food processing water testing, and more.

The biological toxicity tester performs dual functions: toxicity testing and determining microbial contamination. Toxicity testing uses naturally occurring luminescent bacteria, which emit light during normal metabolic processes. If exposed to a toxic environment, their cellular respiration processes are disrupted, resulting in reduced luminescence. The luminescence detector measures the luminescence levels of the luminescent bacteria before and after exposure to a toxic environment. The degree of reduction in luminescence corresponds to the strength of the toxicity. The test results can be compared with standard toxic substances such as HgCl₂ or zinc sulfate heptahydrate to determine the corresponding toxicity level.
