Membrane Filter 简介1. Membrane filters or “membranes” are microporous films with specific pore size 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. 具有特定孔径的微孔滤膜，能使微粒或微生物滞留在膜表面。膜的独特孔径结构具有截留颗粒的能力。 2. 孔径和尺寸：圆片膜的常规孔径为0.22m和0.45m，常规的直径有13mm，25mm,37mm,47mm,90mm,142mm,293mm,其他的直径和尺寸可以根据客户的需要来提供。 3.

Nylon binds protein and should not be used when maximum protein recovery is important.尼龙膜是亲水性膜，适宜于普通水溶液和有机溶液过滤，由于其高蛋白结合力，不宜用于蛋白质的过滤 PES（ Polyethersulfone) Membrane Filter ：PES is a hydrophilic membrane that has very low protein binding and high flow characteristics membrane.PES 是亲水性膜，低蛋白质结合力，高流速 PTFE（Polytetrafluoroethylene） Membrane is hydrophobic and chemically resistant to all solvents, acids and bases. The Membrane is very low in extractables and has an excellent thermal stability.PTFE是疏水性膜，耐强酸，强碱并耐高温，适宜于强腐蚀性溶液和有机溶液以及气体的过滤 我们也可以提供亲水性的PTFE膜CA membrane ：Cellulose Acetate is a very low protein binding membrane that is ideal for aqueous based samples. CA membranes are an excellent choice when maximum protein recovery in the filtrate is critical. Laboratory studies show that CA membranes bind less protein than PVDF or PES membranes.But has a lower chemical resistance than regenerated cellulose. When used with a glass pre-filter in the same housing, these membranes are ideal for filtration of tissue culture media and sensitive biological samples.亲水性膜，低蛋白结合力，适宜于生物样品，蛋白质和水溶液的过滤，不适宜于有机溶液的过滤 PVDF (poly viny lidene fluoride) membrane is a hydrophobic, low protein-binding. PVDF is useful for HPLC sample filtration as well as general biological filtration.疏水性膜，低蛋白结合力，适宜于一般的生物过滤，不适合过滤腐蚀性特别强的溶液 PP (Polypropylenen ) membrane is hydrophobic , has wide chemical compatibility .疏水性膜，化学相容性好PC (Polycarbonate)membrane : smooth surface; Extremely thin and transparent; Precise pore sizes and pore distribution for absolute filtration and separation ; Suitable for fluorescence microscopy, air sampling, cell biology analysis .PC 膜为核孔膜具有光滑的表面，很薄而且透明，孔径精确且分布均匀，适合于显微镜观察，空气采样和微生物分析 RC (Regenerated Cellulose) membrane :Regenerated Cellulose is a hydrophilic, solvent-resistant low protein binding membrane. RC membrane is ideal for removing particulates from HPLC samples, prior to injection.亲水性膜，适合于HPLC（高效液相色谱）样品去除颗粒以及蛋白质的过滤，不适合强酸的过滤Syringe Filter简介 Syringe Filter（一次性针头过滤器）产品线比较完整，使得水溶液和有机溶液都能非常快速而有效的过滤。它们由不同的滤膜和聚丙烯外壳组成（外壳经热封制成）广泛应用于医药、环境、生物技术、食品/饮料和农业测试实验 公司的Syringe Filter常规的过滤孔径是0.22m和0.45m ，主要的直径是13mm,25mm,33mm，17mm和30mm 产品编号说明 以SFPTFE025045NL为例 SF为Syringe Filter 缩写，PTFE为滤膜材质，025表示直径为 25mm， 045表示孔径为0.45 m ，N表示Non-sterile（若为S，则为Sterile），L为Hydrophilic缩写（若为B，则Hydrophobic；P 表示PP Prefilter；G 表示Glass Fiber Prefilter） Syringe Filter 分类1. 按滤膜材质分为Nylon Syringe Filter, PTFE Syringe Filter（有疏水的Hydrophobic Syringe Filter和亲水的Hydrophilic PTFE Syringe Filter 两种）, PES Syringe Filter, CA Syringe Filter, MCE Syringe Filter, Glass Fiber Syringe Filter，PVDF Syringe Filter，PP Syringe Filter.热卖产品Nylon Syringe Filter，PTFE Syringe Filter2. 按照有无预过滤膜分为普通的针头滤器和有预过滤膜的针头滤器（Syringe Filter with prefilter).一般的Syringe Filter是没有预过滤膜的。 Syringe Filter with prefilter是在Nylon，PTFE，PES，PVDF Syringe Filter中增加了PP 或Glass Fiber作为预过滤膜，这样有效地截留了溶液中的颗粒，提高了过滤样品的通过量 3. 按照是否灭菌分为未灭菌的针头过滤器（Non-Sterile Syringe Filter） 和灭菌的针头过滤器（Sterile Syringe Filter）。灭菌的针头过滤器 （Sterile Syringe Filter） 是公司的独特产品，由泡壳和热敏纸热封， 经过Gamma 射线灭菌，尤其是CA 和PES Sterile Syringe Filter在生物实验室中应用较多，也是我们的热卖产品Special Paper分类： Glass Fiber Filter（玻璃纤维滤纸，简写GF） Quartz Fiber Filter（石英纤维滤纸，简写QF） Quantitative Filter Paper（定量滤纸） Qualitative Filter Paper (定性滤纸） pH Indicator Paper(pH 试纸） Glass Fiber Filter 玻璃纤维滤纸Glass Fiber Filter Manufactured from borosilicate glass.
