Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18236

Laboratories filtering viscous or particle-heavy organic solvents frequently encounter rapid membrane clogging issues. Hydrophobic PVDF syringe filters with a 0.8 µm pore size provide a robust solution for clarifying these challenging fluids. The membrane chemistry requires alcohol pre-wetting for aqueous samples but processes organic solvents instantly. An integrated polypropylene prefilter captures larger debris upstream to prevent premature fouling of the main filter. The 25mm housing handles volumes up to 100 mL efficiently while maintaining high flow rates. Sterile packaging ensures that the unit introduces no biological contaminants during critical prefiltration steps.

Key PVDF Membrane Characteristics

Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
0.8 µm pore size delivers efficient clarification and particle removal for viscous or heavily loaded samples without bacterial retention
Exceptional chemical resistance maintains compatibility with aggressive organic solvents, including chlorinated compounds and aromatic hydrocarbons
High flow rates enable the rapid processing of difficult organic samples to improve laboratory efficiency and reduce downtime
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

Accelerate your sample preparation workflows by removing gross particulates before they reach sensitive analytical instruments. You can process viscous or dirty fluids quickly thanks to the rapid 64 ml/min flow rate. The hydrophobic chemistry offers robust resistance against aggressive organic chemicals and solvents used in chromatography. Secure Luer-Lok connections prevent leakage when applying pressure to difficult particulate-laden samples. Rely on the gamma-sterilized packaging to maintain aseptic conditions in your laboratory environment. The robust filtration step extends the life of finer downstream filters and chromatography columns.
