Diamond® PureFlow™ Cellulose Acetate (CA) Syringe Filters

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

  • Low Protein Binding and biologically inert
  • Suitable for aqueous samples
  • High protein recovery from filtrate
  • Ideal for sample analysis that requires maximum recoveries, tissue culture media filtration, and general water filtration
  • pH Range: 4-8

  • Rnase & DNase free
  • 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
