The microbial limit tester is an instrument used to detect the degree of microbial contamination in liquid samples, which has the advantages of simple operation, fast detection, accuracy and reliability.
The principle of the microbial limit tester.
The principle of the microbial limit tester is based on optical detection technology, which calculates the number of microorganisms in a sample by detecting the intensity of scattered light from tiny particles and microorganisms in the sample. The instrument usually consists of a light source, an optical path, a detector, signal processing, and a display. As the sample passes through the instrument, the microbial particles scatter light, and the scattered light intensity is proportional to the number of microorganisms, so the number of microorganisms can be determined by measuring the scattered light intensity.
Application of microbial limit testers.
Microbial limit testers are widely used in pharmaceutical, food, cosmetics, beverage and other industries to detect the degree of microbial contamination in various liquid samples. Specific applications include:
1.Pharmaceutical industry: In the production process of drugs, the degree of microbial contamination needs to be strictly controlled to ensure the quality and safety of drugs. Microbial limit testers can be used to detect the degree of microbial contamination in pharmaceutical products such as APIs, injections, and oral solutions.
2.Food industry: The degree of microbial contamination in food is one of the important indicators to measure food safety. Microbial limit testers can be used to detect the content of bacteria, molds and other microorganisms in beverages, dairy products, meat and other foods.
3.Cosmetics industry: microbial contamination in cosmetics is one of the important causes of **infection. Microbial limit testers can be used to detect the content of bacteria, molds and other microorganisms in cosmetics such as lotions, lotions, and creams.
4.Environmental protection industry: In the fields of sewage treatment and environmental monitoring, microbial limit testers can be used to detect the content of bacteria, viruses and other microorganisms in water bodies, and evaluate the hygiene status and safety of water bodies.
