Glass Fiber Syringe Filters w/ GD-4 Pre Filter, 1.0um , 25mm, Nonsterile, 100/Pk SKU: GD17171

Glass Fiber (GF) Syringe Filters - GD17171

The GD17171 distinguishes itself with integrated GD-4 prefiltration protection that extends service life when processing heavily particulate samples. This 1.0 µm glass fiber membrane system employs a multilayer GF+PP+GF prefilter structure that captures coarse particles before they reach the primary membrane, maintaining consistent flow rates during extended filtration operations. Your laboratory benefits from this 25mm configuration that handles samples up to 50 ml while the depth filtration mechanism distributes particle capture throughout the borosilicate glass fiber matrix for reliable prefiltration in demanding analytical workflows.

Key Membrane Characteristics

1.0 µm glass fiber membrane with GD-4 prefilter provides enhanced particle capacity through multilayer filtration protection
4.08 cm² filtration area in the 25mm diameter configuration processes 50 ml throughput for moderate sample volumes
Borosilicate glass microfiber construction delivers broad chemical compatibility with acids, bases, and organic solvents across applications
Hydrophilic surface characteristics enable immediate aqueous sample processing without requiring pre-wetting steps in your protocols
GF+PP+GF prefilter structure captures coarse particles upstream to protect the primary membrane and extend operational life

Key Construction Characteristics

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

Your prefiltration workflows gain efficiency from the integrated GD-4 prefilter that handles high particulate loads without compromising the primary membrane. The multilayer design captures coarse particles progressively through the prefilter stages before final clarification at the 1.0 µm glass fiber membrane. This 25mm format balances throughput capacity with manageable holdup volume while maintaining the broad chemical resistance that supports diverse solvent systems across pharmaceutical, environmental, and industrial testing applications.
