Diamond® PureFlow™ Polytetrafluoroethylene (PTFE) Syringe Filters - SF-PTFE-2230-S

Diamond® PureFlow™ Polytetrafluoroethylene (PTFE) 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.

Hydrophilic Membrane

• “Universal” membrane – Ideal for both aqueous and organic samples
• Strong chemical stability and inertia
• Strong acid and alkali solvent filtration
• Chemically resistant to all solvents
• pH Range: 1-14

Hydrophobic Membrane

• Strong temperature and chemical conditions
• High durability and fast filtering speed
• Ideal for venting applications, phase separations and aerosol samplings
• 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
