Masterfilter PVDN series filter cartridges are manufactured from an inherently hydrophilic PVDF membrane that offers a broad chemical and temperature resistance. Characterised by its low protein binding properties, the PVDN series is ideal for bioburden reduction, clarification and sterilisation of pharmaceutical and biological solutions. The PVDN cartridges are available in multiple pore sizes with single-layer PVDF membrane. The membranes are easily wettable and fully integrity testable to meet the pharmaceuticals levels for sterility assurance.
