GF Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Nonsterile, 100/Pk SKU: SF18296

Glass Fiber (GF) Syringe Filters - SF18296

The SF18296 combines a 0.45 µm glass fiber membrane with an advanced three-stage GF+PP+GF prefiltration architecture engineered for maximum particle loading capacity. Borosilicate glass microfibers form a depth filter matrix with 250-290 µm thickness that processes samples up to 50 ml while the multilayer prefilter system progressively captures particles before they reach the primary membrane. This 25mm technical configuration serves laboratories processing highly particulate environmental samples, turbid biological fluids, viscous industrial materials, and sediment-laden field collections where conventional single-stage filters would clog prematurely and compromise analytical workflows.

Key Membrane Characteristics

0.45 µm glass fiber membrane with 3-stage prefilter provides superior particle capacity through progressive filtration architecture
4.08 cm² filtration area in the 25mm diameter configuration delivers 50 ml volume throughput for moderate sample processing
Borosilicate glass microfiber construction resists aggressive chemicals, including strong acids, bases, and organic solvents across applications
Hydrophilic surface characteristics facilitate immediate aqueous sample processing without requiring pre-wetting procedures in your workflows
GF+PP+GF prefilter architecture captures coarse particles through three progressive stages before final clarification at the primary membrane

Key Construction Characteristics

Robust polypropylene housing maintains structural integrity under operating pressures up to 87 psi during extended filtration operations
400 µL holdup volume accommodates the multilayer prefilter design while maintaining reasonable sample recovery for your applications
Dual luer-lok/luer slip inlet and outlet connections provide compatibility with standard syringes and automated liquid handling equipment
Autoclavable at 121°C for 30 minutes to support your in-house sterilization protocols when biological applications require it

Quality assurance comes from the three-stage prefilter system that distributes particle capture progressively through multiple layers before final clarification. Your heavily particulate workflows benefit from extended filter life and consistent flow rates even as particle loading accumulates during processing operations. The 25mm format balances throughput capacity with manageable holdup volume while broad chemical resistance supports diverse solvent systems across pharmaceutical, environmental, and industrial testing applications where maximum particle loading capacity protects expensive analytical instrumentation.
