Glass Fiber (GF) Syringe Filters - SF15159

The 0.45 µm hydrophilic glass fiber membrane in 25mm diameter configuration delivers fine particulate removal for clarification applications requiring depth filtration. Technical specifications include 4.08 cm² filtration area, 50 ml volume throughput capacity, 87 psi maximum operating pressure, and temperature capability to 60°C. The depth filtration structure provides high dirt-loading capacity while the finer pore size removes smaller particulates than coarser glass fiber grades. This configuration excels across applications from biological sample clarification to analytical sample preparation where binder-free media prevents extractable contamination.

Key Membrane Characteristics

0.45 µm glass fiber membrane provides depth filtration with effective particulate removal for clarification applications
4.08 cm² filtration area in 25mm diameter format delivers high throughput for processing substantial sample volumes
Hydrophilic surface properties enable rapid aqueous wetting while maintaining compatibility with diverse organic solvents
Maximum operating pressure of 87 psi accommodates viscous samples and challenging matrices during filtration operations
50 ml volume throughput capacity handles large sample volumes efficiently before requiring filter replacement

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 high-volume filtration requirements
Luer-Lok inlet with Luer Slip outlet combines a secure syringe connection with a convenient collection vessel attachment
Nonsterile configuration 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 high dirt-loading capacity that extends filter life with particulate-laden samples, reducing replacement frequency and processing costs. Each filter combines broad chemical compatibility across organic solvents, strong acids, and bases with reliable clarification performance, though you should avoid benzyl alcohol, some esters, and organic oxides which may compromise membrane integrity during processing.
