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. Individually packaged in a peelable blister pack with filter diameter, membrane type, and membrane porosity clearly marked on each package Sterilized by Gamma Irradiation to SAL 10-6 Get the Diamond® PureFlow™ Advantage: Performance - High flow rates and low absorption membranes for minimal sample loss Simplicity - Color coded outer ring 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. Strength - Bonded outer ring on housing provides strength ender higher working pressures for higher performance needs Efficiency - Integral polypropylene pre-filter for high flow rates and fast filtration Quality - Manufacturing process certified to ISO 9001 standard
