一般描述
微孔滤膜是利用高分子化学材料,致孔添加剂经特殊处理后涂抹在支撑层上制作而成,是一种多孔性的薄膜过滤材料,孔径分布比较均匀穿透性的微孔,微孔率高达80‰的绝对孔径.主要用于水系溶液的过滤,故也称水系膜.膜的种类有:尼龙滤膜、混合纤维膜、聚醚砜滤膜、聚偏氟乙烯滤膜、醋酸纤维素滤膜、聚四氟乙烯微孔滤膜等.?
● 颜色:白色?
● 尼龙滤膜具有机械强度高,化学性能稳定,能耐受大多数有机溶剂和多数水溶液过滤等特点.较常应用于普通 HPLC有机溶剂流动相过滤?
● 混合纤维素滤膜具有机械强度高,化学性能稳定,能耐受大多数有机溶剂和多水溶液过滤等特点.较常应用于普通 HPLC有机溶剂流动相过滤?
● 聚醚砜滤膜具有严格孔径分布,其高流率、通量、低蛋白质吸附、强度高等特点,具有亲水性常用作于生物样品的过滤?
● 聚偏氟乙烯滤膜有很好的化学兼容性,能胜任绝大多数的有机溶剂和强腐蚀化学品的过滤.其具有疏水性在用乙醇湿润后可以过滤水相溶液?
● 醋酸纤维素展示了非常低的蛋白吸附能力,它们非常亲水,适用于水溶液和醇溶液.醋酸纤维素膜提高了溶剂的相容性,尤其是对低分子醇类,同时加强了热稳定性?
● 聚四氟乙烯微孔滤膜具有极佳的化学稳定性,可用于其他滤膜不能过滤的极端液体以及温度条件,其具有疏水性可用于空气过滤或者脱气过滤?
● 0.22μm微孔滤膜:能去除样品、流动相中极细颗粒的要求,可以达到GMP或者规定的除菌99.99%的要求?
● 0.45μm微孔滤膜:能滤除大多数细菌微生物;常规样品、流动相过滤,能够满足一般色谱要求?
● 1-5μm:过滤较大颗粒的杂质，或者用于难以处理的浑浊溶液的预处理,可先以1-5μm滤膜过滤,再用相应滤膜进行过滤?
● 规格中所备注的使用温度为该滤膜的最大使用温度

Membrane filters are polymer films with specific pore ratings.Membranes retain particles and microorganisms that exceed their pore ratings by acting as a physical barrier and capturing such particles on the surface of the membrane.It classified into Nylon,MCE,PES,PVDF,CA,PTEE,etc.
● Color:White?
● Nylon membrane has high mechanical strength,chemical stability,can be tolerated by most organic solvents and the majority of water solution filter characteristics.It more often applied to the common organic solvent HPLC mobile phase filtering?
● MCE membrane has high mechanical strength,chemical stability,can be tolerated by most organic solvents and the majority of water solution filter characteristics.It more often applied to the common organic solvent HPLC mobile phase filtering?
● PES membrane has a strict pore size distribution,high flow rate,throughput,low protein adsorption,high strength characteristics.It has a hydrophilic that it commonly used in filter of biological samples?
● PVDF membrane has good chemical compatibility,can be competent for the vast majority of organic solvent and strong corrosion chemical filter.It has a hydrophobic can filter aqueous solution after wetting with ethanol?
● CA (Cellulose Acetate) filters are ideal for protein and enzyme filtrations,tissue culture media sterilization,cold sterilization,biological fluid filtration and other filtration applications where maximum recovery of proteins is critical?
● PTFE membrane has excellent chemical stability.It can be used in extreme liquid and temperature conditions which other membrane can not filter.It has a hydrophobic can be used for air filtration or degassing filter?
● Temperature of specification is max. using Temperature of membrane
