Glass Fiber (GF) Syringe Filters - SF18311

High-volume sample processing often encounters throughput limitations with standard-diameter filters that require multiple filtration cycles or premature replacement during extended operations. The SF18311 addresses this laboratory challenge with a 33mm diameter configuration providing 5 cm² filtration area that processes up to 110 ml sample volumes through a 1.0 µm glass fiber membrane. Your operations benefit from depth filtration technology where borosilicate glass microfibers capture particles throughout the 250-290 µm membrane thickness rather than forming surface blockages, while double luer-lok connections ensure secure attachment during high-volume prefiltration in environmental testing, bioprocess monitoring, and industrial quality control applications.

Key Membrane Characteristics

• 1.0 µm glass fiber membrane provides coarse prefiltration with superior dirt-holding capacity for particulate-laden samples
• 5 cm² filtration area in the 33mm diameter configuration delivers 110 ml volume throughput for high-capacity processing operations
• Borosilicate glass microfiber construction resists aggressive chemicals, including strong acids, bases, and organic solvents, across diverse applications
• Hydrophilic surface properties enable immediate aqueous sample processing without requiring pre-wetting steps in your protocols
• 250-290 µm membrane thickness creates a depth filtration structure that maintains flow rates as particulate loading increases during operations

Key Construction Characteristics

• Durable methacrylate butadiene styrene housing withstands operating pressures up to 87 psi for demanding filtration tasks
• 200 µL holdup volume balances the larger membrane diameter with efficient sample recovery for your processing requirements
• Double luer-lok inlet and outlet connections provide secure, leak-free attachment during extended filtration runs with syringes
• Autoclavable at 121°C for 30 minutes to support your in-house sterilization protocols when biological applications require it

Your high-volume prefiltration workflows gain efficiency from the 33mm format that reduces filtration cycles and processing time compared to smaller diameters. The depth filtration mechanism distributes particle capture throughout the glass fiber matrix while maintaining consistent flow characteristics even as particle loading accumulates. Double luer-lok connections provide secure attachment during extended operations while broad chemical resistance and autoclavable construction support diverse applications across pharmaceutical, environmental, and industrial testing laboratories requiring reliable coarse clarification.
