Speaking of the word needle filter, everyone should be unfamiliar with it, but it doesn’t matter. Below, the needle filter membrane manufacturer will introduce to you the application of needle filters and how to choose needle filter membrane materials.
Needle filters are mainly used for filtration of mobile phases and samples in chromatographic analysis, and are useful for protecting chromatographic columns and infusion pump tubes. It has an excellent effect in preventing the system and injection valve from being contaminated. It is widely used in component analysis, microanalysis, colloid separation and sterility experiments. The needle filter is a disposable product that can be used to remove small bacteria and impurities from liquids, evaporate gas steam, remove dust and remove small bacteria. Sample pretreatment for liquid chromatography can prevent particulate impurities in the sample from clogging the chromatographic column, protect the pump pipeline system and injection valve from contamination, protect the chromatographic system, and extend the service life.
The needle filter membrane produced is the material of the needle filter. The ptfe material has a high degree of chemical stability and excellent chemical resistance, such as resistance to strong acids and strong alkali. , strong oxidants, etc. It has outstanding heat resistance, cold resistance and friction resistance. The long-term use temperature range is -200-+250℃. It also has excellent electrical insulation and is not affected by temperature and frequency.
Needle filter membraneThe pore size is 0.1μm-3μm. The material has the following characteristics: Filtration precision: Membrane pore size Adjustable to obtain different bubble point pressures to meet different filtration precisions. The membrane pore size is evenly distributed to ensure that all small bacteria and impurities are trapped. There is a distinction between hydrophilicity and hydrophobicity. It has high biological reliability and can be used in fields such as pleated filter elements, MBR plates, air filtration, packaging, biological culture, experiments, and sewage filtration.
