Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18231

Laboratories processing small-volume aqueous samples often struggle with premature membrane clogging and sample loss. Hydrophilic PVDF syringe filters with a 0.45 µm pore size address these issues through naturally wettable chemistry and integrated prefiltration. The 13mm housing incorporates a polypropylene prefilter to capture larger debris, significantly extending the life of the final membrane. An ultra-low 10 µL holdup volume ensures maximum recovery for valuable biological fluids and protein solutions. Sterile packaging allows for immediate, contamination-free deployment in critical clarification workflows. Researchers achieve consistent particulate removal for volumes up to 10 mL without requiring time-consuming pre-wetting steps.

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
10 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

Improve your analytical sample preparation with a filtration solution engineered for efficiency and purity. You can process viscous or particulate-laden aqueous fluids reliably thanks to the dual-layer filtration design. The 0.45 µm pore size provides robust clarification to protect downstream instrumentation from damaging particulates. Secure Luer-Lok connections ensure leak-free operation when handling hazardous or valuable liquids. Rely on the gamma-sterilized packaging to maintain aseptic conditions during routine transfer procedures. The low-binding membrane surface preserves the concentration of sensitive biomolecules, making this filter ideal for pharmaceutical and biotechnology applications requiring high recovery.
