Diamond® PureFlow™ syringe filters from Globe Scientific provide high-quality, cost-effective filtration systems that improve the reliability of experimental results and decrease instrument downtime. All Diamond PureFlow syringe filters are constructed of a durable polypropylene housing secured around the membrane with a molded polypropylene sealing ring. This double injection molding process yields a robust filter built to withstand pressures higher than most industry alternatives.

Features 

• High flow rates and low absorption membranes for minimal sample loss.
• Color coded outer ring allows easy identification of membrane and filter media type.
• Bonded outer ring on housing provides strength under higher working pressures for high performance needs.
• Integral PP pre-filter for high flow rates and fast filtration.
