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.

• PVDF (Polyvinylidene Fluoride) hydrophilic membrane
• Low protein binding
• Aqueous and organic samples
• Good resistance to solvents that exhibit low levels of UV absorbing extracables
• Broad chemical compatibility
• Ideal for HPLC sample filtration and general biological filtration
• pH range: 1 to 12
• 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.
