Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18232

Laboratories processing medium-volume aqueous samples often encounter filtration challenges involving high particulate loads. Hydrophilic PVDF syringe filters with a 0.45 µm pore size provide robust clarification without requiring alcohol pre-wetting. The 25mm diameter housing includes an integrated polypropylene prefilter to prevent rapid membrane clogging during processing. The design supports volumes up to 100 mL, ensuring efficient throughput for biological fluids and buffers. Validated sterile packaging allows for contamination-free handling in critical analytical workflows. Researchers benefit from consistent particle removal while preserving the concentration of sensitive proteins.

Key PVDF Membrane Characteristics

Naturally wettable hydrophilic surface eliminates methanol or isopropanol pre-wetting steps, enabling immediate aqueous sample filtration
0.45 µm pore size delivers reliable particle removal and clarification for biological fluids and pharmaceutical solutions
Low protein-binding characteristics minimize the adsorption of biomolecules to preserve concentration in dilute samples
Broad chemical compatibility allows for the safe filtration of various solvents, acids, and bases without degradation
Sterile packaging eliminates initial contamination risks for sensitive analytical samples to support quality assurance requirements

Key Construction Characteristics

Integrated polypropylene prefilter captures coarse particulates upstream of the primary membrane to extend filter lifetime
100 µL holdup volume minimizes loss of valuable pharmaceutical compounds and biological materials optimizing yield
Polypropylene housing delivers structural integrity to 87 psi maximum operating pressure with thermal stability to 60°C
Dual Luer-Lok and Luer-Slip connections accommodate standard syringes without adapters streamlining aseptic transfer procedures

Enhance your laboratory filtration efficiency with a solution designed for difficult aqueous samples. You can process particulate-heavy fluids reliably thanks to the protective integrated prefilter layer. The naturally wettable membrane ensures immediate flow for biological solutions without solvent interference. Secure Luer-Lok connections prevent hazardous leaks when filtering valuable or toxic compounds. Rely on gamma-sterilized packaging to maintain aseptic conditions throughout your sample preparation routine. The low-binding chemistry maximizes the recovery of target biomolecules, supporting accurate analytical results in pharmaceutical and biotechnology applications.
