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.
