Glass Fiber Syringe Filters, 1.0um, 25mm, Nonsterile, 100/Pk SKU: SF18314

Glass Fiber (GF) Syringe Filters - SF18314

The SF18314 combines a 1.0 µm glass fiber membrane with a 25mm diameter configuration engineered for prefiltration applications demanding high throughput and particle retention. Borosilicate glass microfibers form a depth filter matrix that processes up to 50 ml while capturing suspended solids throughout the 250-290 µm membrane thickness rather than forming surface blockages. This technical approach extends filter life when you're processing particulate-laden samples in environmental testing, industrial quality control, and bioprocess development laboratories requiring protection for downstream analytical instrumentation or final filtration steps.

Key Membrane Characteristics

• 1.0 µm glass fiber membrane provides depth filtration with superior dirt-holding capacity for samples containing suspended particles
• 4.08 cm² filtration area in the 25mm diameter delivers 50 ml volume throughput for medium-scale sample processing operations
• Borosilicate glass microfiber construction withstands aggressive chemicals, including strong acids, bases, and organic solvents, across diverse applications
• Hydrophilic surface properties eliminate pre-wetting requirements when processing aqueous samples in your routine laboratory workflows
• 250-290 µm membrane thickness creates multilayer particle capture zones that maintain flow rates as particulate loading increases

Key Construction Characteristics

• Durable polypropylene housing handles operating pressures up to 87 psi for high-flow-rate applications and viscous fluids
• 100 µL holdup volume balances sample recovery with the larger membrane diameter for efficient material utilization
• Dual luer-lok/luer slip inlet and outlet connections provide compatibility with standard syringes and automated liquid handling equipment
• Autoclavable at 121°C for 30 minutes to support your in-house sterilization protocols when biological applications require it

Quality assurance comes from depth filtration mechanics that distribute particle capture throughout the glass fiber matrix rather than relying on surface retention alone. Your prefiltration workflows benefit from consistent flow characteristics even as particle loading accumulates during extended sample processing runs. The 25mm format handles moderate sample volumes efficiently while maintaining the broad chemical resistance that supports diverse solvent systems across pharmaceutical, environmental, and industrial testing applications where you need reliable particle removal before chromatography or final sterilization steps.
