Glass Fiber (GF) Syringe Filters - SPEC20235

The 33mm glass fiber syringe filter combines a 2.7 µm pore size with 5 cm² filtration area engineered for high-volume coarse prefiltration applications. Borosilicate glass microfibers form a depth filter matrix with 250-290 µm thickness that processes up to 110 ml throughput while capturing suspended particles throughout multiple layers rather than forming surface blockages. This large-diameter configuration serves diverse laboratory needs from environmental sample preparation to bioprocess monitoring, industrial quality control to agricultural testing, where heavily contaminated samples require robust particle removal before downstream analytical measurements or final filtration steps.

Key Membrane Characteristics

2.7 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 needs
Borosilicate glass microfiber construction resists aggressive chemicals, including strong acids, bases, and organic solvents, across diverse applications
Hydrophilic surface properties eliminate pre-wetting requirements when processing aqueous solutions in your laboratory protocols
250-290 µm membrane thickness creates a multilayer particle capture structure that maintains flow rates as particulate loading increases

Key Construction Characteristics

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

Quality assurance comes from depth filtration mechanics that distribute particle capture throughout the glass fiber matrix. Your high-volume prefiltration operations benefit from the 33mm format that processes larger sample quantities efficiently while the 2.7 µm pore size handles heavily contaminated materials without premature clogging. The double luer-lok connections provide secure attachment during extended filtration runs while broad chemical resistance supports diverse solvent systems across pharmaceutical, environmental, and industrial testing applications.
