The vacuum suction filter device is a commonly used instrument in the laboratory. The St. Stephen's sciencetool brand is a professional laboratory vacuum filter device supplier. Its brand vacuum vacuum filter device is rich in models and can be used for vacuum pumping of different needs of the laboratory. Filtration, this article briefly introduces which type of suction filter should be selected for different pumping requirements in the laboratory.

1. Suspended solids inspection SS vacuum filtration: R300SS suspended solids inspection and filtration device is specially designed for environmental monitoring, water quality and water conservation, environmental protection enterprises for the inspection of suspended solid particles in water samples. Standard components include a 0.45 micron filter membrane, a filter funnel, a suction filter bottle, a vacuum pump, a buffer cup, and a pressure regulator. Each component required for the filtration of the suspension is convenient for the user to receive the instrument and directly filter. Experiments, no need to buy separately, more convenient. The suction filter bottle has a bottom drain port to facilitate rapid discharge of the filtrate after the filter bottle is full; the filter funnel is designed with a rotary card design, and the filter can be removed by simply rotating the filter bowl. These designs simplify the process of changing the membrane, draining the filtrate, and saving time. The hose port of the suction filter bottle is equipped with a protective cap to prevent the plugging hose from being too strong to break the interface; the suction filter bottle has a fixed base to prevent the waste liquid bottle from shaking and pouring; the filter funnel is made of polyethersulfone PES. It has a certain resistance to falling; the filter end of the vacuum suction pump with anti-waste liquid suction filter and buffer cup effectively protects the vacuum pump. These designs can effectively protect the entire vacuum pumping device, effectively avoiding the misuse of the instrument.

2. Dust filtration of micro-samples: When using a small amount of sample or a very precious solvent in the laboratory, if a conventional 47 or 50 mm filter is used, it will increase the unnecessary loss of the sample or solvent. In this case, you should choose 25mm. Diameter filter unit R300MF, smaller filter membrane can significantly reduce sample loss

3. Chromatographic mobile phase filtration: R300MF mobile phase filtration device is a suction filtration device specially designed for HPLC liquid chromatography mobile phase filtration. The R300MF mobile phase filtration device includes a suction pump and a mobile phase solvent. A set of filter bottles can be used to remove various impurities in the chromatographic mobile phase, thereby effectively improving the service life of the column and also having a certain degassing effect;

4. Sterilization filtration: sterilization filtration is usually the filtration of laboratory reagents, buffers or culture fluids. R300-500 vacuum filtration equipment can be used, one vacuum filtration pump and 500ml top filtration. One, 500ml blue cap reagent bottle, after the filtration test, the bottle top filter can be removed, and the reagent bottle cap can be directly screwed onto the reagent bottle to avoid secondary pollution and very easy to filter. Preservation of samples;

5. Microbial limit detection: The microbial limit detector is a filtering device used by pharmaceutical companies, food factories, water plants, sewage treatment plants, environmental testing institutions or university research institutes to detect microorganisms in water. Users can select the amount of samples to be filtered according to the needs. The L400-S1 vacuum filtration device for filtering one sample at a time, the BV330B microbial limit filtration system for simultaneously filtering three samples at the same time, and the BV630B microbial limit filtration system for simultaneously filtering six samples at the same time.
