Microbial limit detector is an instrument used to detect the microbial content in a sample, which is widely used in medicine, food, cosmetics, medical equipment and other fields. This article will introduce the principle, application scope, use method and precautions of the microbial limit detector.
1. The principle of microbial limit detector
The microbial limit tester uses the principle of membrane filtration, which captures the microorganisms in the sample on the filter membrane, and then counts and identifies the microorganisms on the filter membrane to obtain the amount of microorganisms in the sample. The instrument has the characteristics of high degree of automation, easy operation and accurate detection.
Second, the application scope of the microbial limit detector
1.Pharmaceutical field: used for microbial limit testing of drugs, biological products, medical devices and other products to ensure the safety and effectiveness of products.
2.Food field: used for microbial content detection of food, beverages, health products and other products to ensure the hygiene and quality of products.
3.Cosmetics: used for microbial content detection of cosmetics, skin care products and other products to ensure the safety and effectiveness of products.
4.Environmental monitoring field: It is used for the detection of microbial content in water sources, air and other environments, to understand the distribution of microorganisms in the environment, and to provide a scientific basis for environmental protection.
3. How to use the microbial limit detector
1.Preparation: Prepare the required equipment such as the sample to be tested, the filter membrane, and the sterile table.
2.Sample Handling: The sample to be tested is properly processed, such as dilution, filtration, etc., to facilitate subsequent microbial detection.
3.Filtration: The treated sample is filtered through a filter, leaving microorganisms on the membrane.
4.Microbial enumeration: Count and identify the microorganisms on the filter membrane, and calculate the amount of microorganisms in the sample based on the counting results.
5.Result report: Prepare a report based on the test results, including the name of the sample, the test item, the test result, the conclusion, etc.
Fourth, the main features of the microbial limit detector EJ-XDY-300
1. Built-in diaphragm liquid pump, no need to suction filter bottle, direct liquid discharge, simple operation, higher efficiency;
2. The integrated ultra-small design of the microbial limit detector reduces the occupation of the operation space of the laminar flow table
3. No tools required, easy to assemble or disassemble by hand;
4. It can suction and filter three filter membranes at the same time, which greatly improves the work efficiency
5. The filter bowl is designed with reusable materials, which is durable, cost-saving and easy to operate
6. Each filter head adopts independent control, which is convenient for operators to use flexibly
7. The edge of the filter head with groove design makes it safe and simple to release and take out the film.
In short, the microbial limit detector is an important microbial testing instrument, which is widely used in medicine, food, cosmetics and other fields. In the process of use, pay attention to the operating procedures and maintenance requirements to ensure the accuracy and reliability of the instrument. At the same time, it is necessary to do a good job of cleaning and maintenance after use to prolong the service life of the instrument.
