The syringe filter is mainly applied for filtration of mobile phase and sample when in chromatographic analysis. It has good effects on protecting chromatographic column, infusion pump pipe, and sample valve from being polluted. The syringe filter is widely used for gravimetric analysis, microanalysis, colloid separation, and sterility test.
There are different membrane materials which are used for making syringe filters, and many of them have their own characteristics.
The Poly Tetra Fluoro Ethylene (PTFE) membrane is suitable for hydrophilic and all sorts of organic solvents. It is resistant to all solvents with low solubility.
The Poly Tetra Fluoro Ethylene (PTFE) membrane is suitable for hydrophilic and all sorts of organic solvents. It is resistant to all solvents with low solubility.
Moreover, the PTFE membrane filter is breathable and impermeable, with the advantages of large air flow rate, high particle filtration efficiency, good thermal endurance, excellent aging resistance, non-stick performance, noninflammability, and biocompatibility. The syringe filter with PTFE membrane is widely applied in the areas of the chemical industry, pharmaceutical industry, environmental protection, electronic industry, food industry, and energy industry.
The Polyether Sulfone (PES) membrane has good chemical and heat stability, with high flow rate, strong acid, and alkali resistance and high mechanical strength.
The organic nylon membrane filter has good hydrophily and is resistant to acid, alkali, and antioxidant. It is not only suitable for water solution, but also organic solvent.
