Syringe Filter, PTFE Hydrophobic Membrane, 0.22μm Porosity, 13mm Diameter, PP Housing, Non-sterile, Bulk Packed, Red, Box of 100

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 preperation, 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.

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 under higher working pressures for high performance needs
• Efficiency - Integral polypropylene pre-filter for high flow rates and fast filtration
• Quality - Manufacturing process certified to ISO 9001 standards
