1) patent: special "three claw" membrane filter apparatus fastener design, fetching, convenient for single hand operation and membrane has the advantages of simple operation, the use of more efficient.
2) modular design: the solvent filter system connector is equipped with an independent switch, can be a separate sample filter, but also can filter multiple samples at the same time, in the detection of a large number of samples can save a lot of time.In the process of filtration, the utility model adopts an integrated solution, a non pollution oil-free piston vacuum pump and a liquid storage bottle which can be sterilized by high temperature. The whole filtration system can be placed safely and efficiently in the laboratory, clean room, clean bench.
3) design detailed scientific: first using high-quality 316L stainless steel membrane support pad, ensure the membrane does not appear rupture or perforation in the filtration process, guarantee the accuracy of sample testing, it can make the entrapped microbial distribution in the membrane surface is uniform, then the experimental results in observation.
4) to prevent secondary pollution: filtration system in stainless steel filter cup is arranged on the upper cover of air vents, air filter installed optional, to avoid the two pollution in filtration.
5) to improve the efficiency of detection: to improve the efficiency of detection: stainless steel filter sterilization method can adopt 121 degrees sterilization for 20-30 minutes, 180 degrees 60 minutes, dry heat sterilization can be used more efficient sterilization method: the filtration system matching with high temperature burning flame sterilizer, achieve sterilization purpose. The inner wall of the filter cup is provided with a clear capacity calibration line, which is convenient for quantitative addition.
6) 6 durable material: filter, filter connector, valve, filter holder, filter cover, membrane support pad and other major accessories are made of 316 high-quality stainless steel, not easy to damage.
