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.

PTFE (Polytetrafluoroethylene) 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 to 14
- Female Luer lock inlet/male Luer slip outlet

PTFE (Polytetrafluoroethylene) 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 to 14
- Female Luer lock inlet/male Luer slip outlet

Performance: High flow rates and low absorption membranes for minimal sample loss. Filters have a color coded outer ring which 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. The bonded outer ring on housing provides strength under higher working pressures for higher performance needs. The integral polypropylene pre-filter for high flow rates and fast filtration ensures efficiency.
