Diamond® PureFlow™ Polyethersulfone (PES) Syringe Filters

Diamond® PureFlow™ Polyethersulfone (PES) 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
  • Suitable for 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: 1-14

  • 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

Non-sterile Diamond PureFlow syringe filters are perfect for use in a wide range of filtration and sample applications where sterility is not needed. Non-sterile filters are used in  analytical chemistry for sample preparation, HPLC operations, and protecting analytical equipment from particle contamination.

  • Bulk packaged with filter membrane type and membrane porosity printed on each filter
  • Polypropylene microfiber pre-filter layer to improve filtration of particulate-laden fluids
