Glass Fiber Syringe Filters, 1.2 um, 13mm, Nonsterile, 100/Pk SKU: SF18315

Glass Fiber (GF) Syringe Filters - SF18315

The SF18315 delivers depth filtration through a 1.2 µm glass fiber membrane engineered for coarse clarification where particulate-laden samples would quickly overwhelm surface-retention filters. Borosilicate glass microfibers capture particles throughout the 250-290 µm membrane thickness rather than forming surface blockages, extending service life during prefiltration operations. Your laboratory workflows benefit from this compact 13mm configuration that processes samples up to 10 ml while minimizing holdup volume to just 20 µL when working with limited quantities or expensive reagents requiring efficient recovery.

Key Membrane Characteristics

• 1.2 µm glass fiber membrane provides coarse clarification with depth filtration mechanics for samples containing suspended particles
• 1.09 cm² filtration area in the 13mm diameter handles smaller sample volumes efficiently with 10 ml throughput capacity
• Borosilicate glass microfiber construction delivers broad chemical compatibility across acids, bases, and organic solvents without extractables
• Hydrophilic surface characteristics allow immediate processing of aqueous solutions without requiring pre-wetting steps in your protocols
• 250-290 µm membrane thickness creates a multilayer particle capture structure that maintains flow rates as particulate loading increases

Key Construction Characteristics

• Robust polypropylene housing withstands operating pressures up to 87 psi for demanding filtration applications
• 20 µL holdup volume preserves valuable samples when processing limited-quantity materials or costly reagents
• Dual luer-lok/luer slip inlet and outlet connections fit standard laboratory syringes and automated dispensing systems
• Autoclavable at 121°C for 30 minutes to support your sterilization protocols when biological applications require it

Your prefiltration operations gain efficiency from depth filtration that distributes particle capture throughout the glass fiber matrix. The compact 13mm format suits smaller sample volumes while maintaining the broad chemical resistance that supports diverse solvent systems across pharmaceutical, environmental, and industrial testing applications. This nonsterile configuration offers flexibility where you can autoclave filters before use or employ them directly for non-biological sample preparation in routine laboratory workflows.
