一般描述
产品介绍：
这些亲水的、极低的可萃取物/蛋白质结合的 PVDF 膜过滤器为侵蚀性溶剂型流动相应用、生物灭菌/澄清和 HPLC/分析样品制备提供高流速和通量。 PVDF 膜不需要使用润湿剂，在灭菌或澄清过程中传输可忽略不计的可萃取物并提高样品纯度。由于其极低的蛋白质结合水平 - 甚至低于类似的尼龙、硝酸纤维素和 PTFE 膜 - 我们的 PVDF 过滤器在制备用于色谱和其他仪器分析的蛋白质溶液时得到了很好的应用。广泛的化学兼容性使这些 PVDF 过滤器能够适应广泛的应用——尤其是那些需要高流速/通量的应用——包括流动相中的腐蚀性/非腐蚀性酸、醇和溶剂。我们的多功能 PVDF 膜过滤器可提供 0.22 或 0.45 μm 的孔径；然而，0.22 μm 孔径更适合去除 uHPLC 污染物，这些污染物很可能堵塞色谱柱并损坏分析结果。
产品应用：
水相和兼容的有机 HPLC 样品和流动相 蛋白质水溶液（培养基或细胞裂解物）的过滤/灭菌 水溶液（强酸、强碱和氧化剂）和兼容溶剂（醇、芳香烃）的过滤

Product Describtion:
These hydrophilic, extremely low extractable/protein binding, PVDF membrane filters provide high flow rates and throughputs for aggressive, solvent-based mobile phase applications, biological sterilization/clarification, and HPLC/analytical sample preparation.?
PVDF membranes do not require the use of wetting agents, transmitting negligible extractables and increasing sample purity during sterilization or clarification procedures. Because of their exceptionally low protein binding levels--even lower than similar nylon, nitrocellulose, and PTFE membranes--our PVDF filters are well-utilized in the preparation of proteinacious solutions for chromatography and other instrumental analyses. Broad chemical compatibility allows these PVDF filters to accommodate a wide range of applications--especially those requiring high flow rates/throughput--including aggressive/non-aggressive acids, alcohols, and solvents in mobile phase. Our versatile PVDF membrane filters are available with pore sizes of either 0.22 or 0.45 μm; however, the 0.22 μm pore size is preferred for the removal of uHPLC contaminants most likely plug columns and damage analytical results.
Product Application：
PVDF Membrane Filter Applications：Aqueous and compatible organic HPLC samples and mobile phases Filtration/sterilization of proteinaceous aqueous solutions (culture media or cell? lysate) Filtration of aqueous solutions (strong acids, bases, and oxidizers) and compatible solvents (alcohols, aromatic hydryocarbons)
