Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18226

Analytical laboratories handling precious micro-volume samples face the dual challenge of preventing loss and ensuring purity. Hydrophobic PVDF syringe filters with a 4mm diameter provide an optimized solution for volumes less than 1 mL. The membrane features a 0.45 µm pore size that clarifies organic solvents effectively without stripping essential chemical components. An ultra-low 1 µL holdup volume ensures that virtually every drop of the sample is recovered for analysis. Operators must pre-wet the unit with alcohol for aqueous fluids, though it excels with aggressive organic mixtures. Sterile packaging guarantees contamination-free processing for critical applications.

Key PVDF Membrane Characteristics

Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
0.45 µm pore size removes particulates from analytical samples to protect chromatography instrumentation without sterile-grade bacterial retention
Exceptional chemical resistance maintains compatibility with aggressive organic solvents, including chlorinated compounds and aromatic hydrocarbons
High structural stability preserves membrane performance under pressure while filtering small volumes of viscous fluids
Sterile packaging eliminates initial contamination risks for sensitive analytical samples to support quality assurance requirements

Key Construction Characteristics

Ultra-low 1 µL holdup volume maximizes recovery by minimizing sample retention for expensive analytical standards
Polypropylene housing provides structural integrity to 87 psi maximum operating pressure for operational confidence
Dual Luer-Lok and Luer-Slip connections accommodate standard laboratory syringes without adapters to streamline workflow integration
Compact 4mm housing design minimizes dead volume to ensure the efficient processing of samples less than 1 mL

Maximize your analytical recovery by switching to a filtration unit designed specifically for limited-volume applications. You can clarify expensive standards and rare compounds with confidence using the ultra-low holdup design. The hydrophobic membrane withstands aggressive chemicals found in chromatography mobile phases to prevent degradation. Secure Luer-Lok connections prevent hazardous leaks even when handling very small syringes. Rely on the gamma-sterilized packaging to maintain aseptic conditions during critical transfer steps. Consistent clarification protects your HPLC columns from particulate damage and extends the operational life of sensitive instrumentation.
