Sterile Diamond® PureFlow™ syringe filters satisfy requirements of life science applications for sterilization of solutions or clarification of biological fluids. Sterile filters include a polypropylene (PP) microfiber pre-filter layer to improve filtration of particulate-laden fluids that are difficult to filter with single layer syringe filters.

• PES (Polyethersulfone) membrane
• Low protein binding
• Aqueous and organic samples
• High flow rates and throughput and compatible with high temperature liquids
• Ideal for tissue culture filtration, filtration of proteins and nucleic acids, and chromatography
• pH range: 1 to 14
• Female Luer lock inlet/male Luer slip outlet

Performance: High flow rates and low absorption membranes for minimal sample loss. Filters have a color coded outer ring which allows easy identification of membrane and filter media type. Each unit is clearly marked with an identifying code to denote pore size and membrane material. The bonded outer ring on housing provides strength under higher working pressures for higher performance needs. The integral polypropylene pre-filter for high flow rates and fast filtration ensures efficiency.
