Let's take a look at how microbial limiters work

Let's take a look at the working principle of microbial limit microbial limit meter is widely used in research, inspection and quarantine agencies, quality control agencies, natural mineral water industry, drinking water industry, pharmaceutical industry, beverage industry and other departments of filtration membrane microbial detection, suspension solids detection, sample purification filtration equipment
.

The principle is that the vacuum pump forms a negative pressure environment, and the liquid sample to be detected is separated by the microorganism or solid that is smaller than the micropores of the filter membrane through the filtration of the microporous membrane for the next step of detection and analysis
.

This product is preferably polished sanitary grade 304 stainless steel, can resist most corrosive liquids, can be autoclaved as a whole, microbial limiter (stainless steel filtration system) can be carried out at the same time (single, three, six) sample filtration, only a real air source can complete all operations, saving a lot of time, convenient and fast
.

Microbial limit meter is called a lot, also called microbial limit inspection instrument, there is also called membrane filtration system, and can also be more concise and directly called microbial limit meter
.

Microbial limit detection (1) sterile examination of Chinese and Western drugs for injection and large infusion; (2) microbial limit examination, which is used for oral counting of miscellaneous bacteria such as Chinese and Western drugs, cosmetics, food, health food, etc.
, can be used for semi-solid, suspension, solid and other sample examination; (3) clinical laboratory examination of bacteria in body fluids, blood products and veterinary drug products; (4) sterilization filtration
of a small amount of test materials.

Four major application aspects of microbial limit meter: 1.
Pharmaceutical: microbial limit examination of purified water, water for injection, APIs and oral liquids, tablets, capsules, biological products and preparations; 2.
Disease control: air conditioning condensate, drinking water and other water quality of the total number of bacteria inspection, pathogenic bacteria detection; 3.
Food: the total number of colonies of food and beverage, mineral water, pure water is checked; 4.
Chemical: all kinds of water samples that need to be tested for microorganisms
.

The filter element is the core part of the microbial limit meter, and the filter element is composed of special materials, which is a suitable loss part and needs special protection
.

When removing impurities, special attention should be paid to the precision filter element, which must not be deformed or damaged, otherwise the purity of the filter element installed after filtration does not meet the design requirements
