Glass Fiber Syringe Filters, 0.45 um, 13mm, Nonsterile, 100/Pk SKU: SF18312

Glass Fiber (GF) Syringe Filters - SF18312

Analytical laboratories require clarification solutions that remove particulates without introducing extractables into sensitive assays. The SF18312 meets these industry standards with a 0.45 µm glass fiber membrane designed for sample preparation across chromatography, spectroscopy, and molecular biology workflows. Your applications benefit from depth filtration technology that captures particles throughout the borosilicate glass fiber matrix while the compact 13mm design handles smaller sample volumes efficiently without excessive holdup losses.

Key Membrane Characteristics

• 0.45 µm glass fiber membrane delivers clarification performance for particulate removal in analytical sample preparation workflows
• 1.09 cm² filtration area in the 13mm configuration processes up to 10 ml throughput for your routine laboratory samples
• Borosilicate glass microfiber construction provides chemical resistance across acids, bases, and organic solvents without contributing contaminants
• Hydrophilic surface characteristics enable immediate aqueous sample processing without requiring pre-wetting steps in your protocols
• 250-290 µm membrane thickness creates a depth filtration structure that extends filter life when processing moderately particulate samples

Key Construction Characteristics

• Robust polypropylene housing maintains integrity under operating pressures up to 87 psi during filtration operations
• 20 µL holdup volume preserves precious samples when working with limited quantities or expensive reagents
• Dual luer-lok/luer slip inlet and outlet connections accommodate standard laboratory syringes and automated dispensing systems
• Autoclavable construction at 121°C for 30 minutes supports your in-house sterilization protocols when required

Your analytical workflows gain reliability from depth filtration that maintains consistent flow rates as particle loading increases. The 13mm format suits smaller sample volumes while the broad chemical compatibility supports diverse solvent systems across pharmaceutical testing, environmental analysis, and life science research. This nonsterile configuration offers flexibility for your quality control applications where you can autoclave filters before use or employ them directly for non-biological sample preparation.
