The syringe filter membrane filter is mainly used for the filtration of mobile phase and samples in chromatographic analysis. It plays a good role in protecting the chromatographic column, infusion pump pipe system and sample injection valve from pollution. It is widely used in gravimetric analysis, microanalysis, colloid separation and sterility test. Suitable for water system and various organic solvents, resistant to all solvents and low solubility. It has the characteristics of air permeability and impermeability, large air flux, high particle interception rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, aging resistance, non stick, non combustible, non-toxic and biocompatibility.
