Millex® Syringe Filters, Polyethersulfone

Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results and decreases instrument downtime.

• Non-sterile Millex® syringe filters contain Millipore Express™ PLUS polyethersulfone (PES) membrane
• Enables fast filtration of aqueous and mild organic solutions, 0,22 μm pore size diameters to suit your application needs
• Low protein binding for maximum sample recovery
• Holdup volume: ≤15 μl (after air purge) hydrophilic
• Bubble point: ≥4,1 bar, air with water at 23 °C
• Height: 21 mm

Disposable syringe filters are commonly used for fast and efficient filtering. Selection should be by application. Sterile syringe filters are used to sterilise solutions or clarify sterile solutions, while nonsterile syringe filters are used for general filtration and sample purification. Syringe filters are categorized by two essential characteristics - membrane and filter housing.

Both characteristics must be compatible with the application and solution being filtered. Syringe filter membranes are matched by composition, filter diameter, and pore size, while syringe filter housings are matched to end applications based on composition and format.

Techniques: UHPLC, analytical sample preparation, fast flow filtration and low protein-binding filtration.
