Syringe filter is mainly used for chromatographic analysis of mobile phase and samples of filtering. The influences that protect chromatographic column, infusion and injection valve handle system away from pollution are obvious and effective. The syringe filter can be used in the aspect of gravimetric analysis, microanalysis, colloid separation and sterility test.
Material and characteristics of syringe filter
A: PTFE (polytetrafluoroethylene)
Suitable for water system and various kinds of organic solvent, wide application, low solubility, ventilation water-proof, well gas flux, interception rate high particles, resistant temperature well, strong acid alkali resistant organic solvent and antioxidant, aging and not sticky incombustible and non-toxic biocompatibility etc. The related products widely used in chemical medicine environmental protection electronic food energy.
B: PES (polyether sulfone)
High chemical and thermal stability, fast speed acid and alkali resistant ability (pH range 1-14); with high mechanical strength
C: Organic nylon 6
Good hydrophilic, acid and alkali resistant, antioxidant applies not only to contain acid and alkaline solution, more applicable to contain organic solvent, such as alcohol hydrocarbons lipid phenol ketene organic solvents
D: Organic nylon 66
The product is suitable for use in most organic solvents and aqueous solution, and can be used in acid, 70% ethanol ethylene chloride organic solvent such as high temperature resistant, good strength, stable in chemical
E: PVDF (Polyvinylidene fluoride)
Chemical stability and inert, applies to the chemical strong corrosion organic solvents, acid and alkali solution, high performance liquid chromatographic analysis of sample preparation. It has hydrophobic characteristics, can filter out moisture in the air and gas. PVDF film is laminated to support online, have very strong strength and operability, high temperature resistance can be 130 degrees
