Whatman™ Membrane Filter Pressure Filtration Devices
Whatman® pressure filtration devices with a sample loading cylinder are suitable for batch filtration of samples from 20mL. Devices without infusion cylinders are "In-Line" type filters and are suitable for larger volumes of several liters. Filtration of liquids and gases is possible, including sterile filtration of serums or the clear filtration of media that are difficult to filter, especially those that are highly viscous. Membranes, paper or glass fiber filter discs can be used. Cleaning and changing of filters is completed in a few steps.All pressure filtration devices units are equipped with pressure resistant filter supports. High quality silicone or PTFE O-rings seal these systems securely. Please ensure you only use intact seals for safety reasons. PTFE versions are recommended for use with corrosive media.
