Brief introduction

In the field of water quality testing, especially in response to emergencies, conventional analytical methods require complex and expensive instruments, long testing times, and single analysis items, which cannot provide fast, accurate, and reliable analysis reports for emergencies. AmericaUniBestThe group company provides you with a toxicity analyzer for rapid detection of water quality conditions. You can quickly assess the toxicity of water quality and provide scientific and reliable analysis reports with just a few simple steps.

SafeLight miniHandheld ultra portable biological toxicity analyzer, combined with the United StatesUniBestThe group company has many years of experience in producing chemiluminescence instruments. It has been widely used in environmental emergency monitoring, disease control centers, water quality and safety monitoring of water companies, public security anti-terrorism emergency monitoring, food safety emergency monitoring, and water quality and safety assurance of field armies, and has obtained highly sensitive and stable reliable detection results.

2、 Working principle

SafeLight miniThe handheld ultra portable biotoxicity analyzer is a toxicity detection system based on biosensing technology, which qualitatively and quantitatively detects the changes in luminescence intensity of luminescent bacteria during metabolism. This instrument uses luminescent bacterial freeze-drying reagents. When these bacteria are in a toxic environment, their emitted light is inhibited, and the toxicity of the sample can be quickly and accurately tested based on changes in their luminescence intensity. It can directly detect thousands of potential toxic substances.
