Glass Fiber (GF) Syringe Filters - SF14698

The 0.7 µm hydrophilic glass fiber membrane in a 25mm diameter configuration delivers exceptional throughput for high-volume viscous sample processing. Technical specifications include 4.08 cm² filtration area, 250 ml/min flow rate, 50 ml volume throughput capacity, and 87 psi maximum operating pressure. The depth filtration structure provides high dirt-loading capacity that traps particulates throughout the membrane thickness rather than solely at the surface. This glass fiber configuration excels across diverse applications from viscous biological sample prefiltration to aggressive chemical clarification where binder-free media prevents extractable contamination.

Key Membrane Characteristics

0.7 µm glass fiber membrane delivers depth filtration with exceptional dirt-loading capacity for extremely viscous and particulate-laden samples
4.08 cm² filtration area in 25mm diameter format provides high throughput capacity for processing larger sample volumes efficiently
Hydrophilic surface properties enable immediate wetting with aqueous solutions while maintaining compatibility with organic solvents
Flow rate of 250 ml/min ensures rapid processing of viscous samples that would generate excessive pressure in standard membranes
50 ml volume throughput capacity handles substantial sample volumes before requiring filter replacement, reducing processing costs

Key Construction Characteristics

Polypropylene housing construction provides chemical resistance appropriate for aggressive solvents, acids, and bases
100 µL holdup volume minimizes sample waste while accommodating the larger filtration area requirements
Luer-Lok inlet with Luer Slip outlet combines secure syringe attachment with convenient collection vessel connection
Nonsterile supply format arrives autoclavable at 121°C for 30 minutes or gamma irradiation at 25 kGy when protocols require sterile operation

Your nonsterile filters accommodate gamma irradiation or autoclave sterilization for integration into laboratory protocols. The glass fiber depth filtration structure enables exceptional dirt-loading capacity that extends filter life significantly with challenging samples. Each filter combines broad chemical compatibility across organic solvents, strong acids, and bases with high throughput performance, though you should avoid benzyl alcohol, some esters, and organic oxides which may compromise membrane integrity during extended exposure.
