Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18220

Laboratories processing turbid organic solvents often face rapid clogging issues with standard filters. Hydrophobic PVDF syringe filters with a 3.0 µm pore size provide a cost-effective solution for coarse prefiltration. The membrane requires alcohol pre-wetting for aqueous samples but processes organic fluids immediately. A compact 20mm ABS housing features threaded double Luer Lock connections for secure attachment. Users can autoclave the nonsterile units to achieve sterility when needed for specific protocols. The flexible design efficiently handles medium-volume samples, protecting downstream equipment from particulate damage.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires pre-wetting with alcohol before processing aqueous samples, but allows direct filtration of organic solvents
• Coarse 3.0 µm pore size delivers efficient clarification and particle removal for heavily loaded samples without bacterial retention
• Exceptional chemical resistance maintains compatibility with aggressive organic solvents, including chlorinated compounds and aromatic hydrocarbons
• Naturally hydrophobic surface enables gas venting applications by efficiently displacing air from liquid handling systems
• Extended temperature stability to 80°C accommodates warm sample filtration and autoclave sterilization cycles without degradation

Key Construction Characteristics

• Threaded double Luer Lock connections secure both inlet and outlet ports to eliminate disconnection risks
• Durable ABS housing withstands operating pressures to 72.5 psi providing mechanical strength for demanding protocols
• Nonsterile construction allows for autoclave sterilization before first use providing economical prefiltration capability
• 20mm diameter platform supports medium-volume clarification balancing processing capacity with material economy

Maximize your laboratory budget with a prefiltration solution designed for flexibility and economy. You can remove large debris from organic solvents without the cost of pre-sterilized units. The 3.0 µm pore size extends the life of finer downstream filters significantly. Threaded double Luer Lock connections prevent hazardous leaks when filtering toxic fluids under pressure. Rely on the autoclavable design to provide sterility only when your specific protocol demands it. The durable configuration protects analytical instruments from damage caused by heavy particulate loads. Choose this reliable filter for your routine sample preparation tasks.

Hydrophobic

• Viscous Sample Prefiltration — Handle high-viscosity pharmaceutical formulations where larger pores maintain flow without premature clogging
• Environmental Sample Processing — Prefilter turbid soil extracts and water samples, removing coarse solids before fine filtration or analysis
• Chemical Manufacturing — Process particulate-laden intermediates where solvent resistance maintains membrane performance throughout production
• Biological Sample Clarification — Remove large cellular debris from lysates before fine filtration, protecting downstream membranes from fouling
• Equipment Protection — Guard analytical instrumentation from coarse particulates that damage pumps, detectors, and chromatography columns
• Quality Control Prefiltration — Prepare heavily particulate samples where autoclave sterilization provides contamination control at lower cost
