Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18233

Laboratories handling large volumes of viscous biological fluids often face slow filtration rates and premature clogging. Hydrophilic PVDF syringe filters with a 0.45 µm pore size solve this by providing rapid clarification without alcohol pre-wetting. The large 33mm housing includes an integrated polypropylene prefilter to capture coarse debris effectively. A high effective filtration area of 4.9 cm² enables the processing of volumes exceeding 100 mL. Researchers benefit from the low-binding membrane chemistry which preserves the concentration of proteins in dilute samples. Validated sterile packaging ensures that the device introduces no contamination during critical workflows.

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 maximizes yield for medium-volume sterile processing applications optimizing sample recovery
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

Maximize your laboratory throughput with a filtration solution designed for difficult aqueous samples. You can process particulate-laden buffers and media efficiently thanks to the high-capacity prefilter design. The naturally wettable membrane ensures immediate flow and robust particle retention for analytical applications. Secure Luer-Lok connections prevent hazardous leaks when filtering valuable or toxic solutions under pressure. Rely on gamma-sterilized packaging to maintain aseptic conditions throughout your sample preparation routine. The durable polypropylene housing withstands operating pressures up to 87 psi, ensuring reliable performance across diverse bioprocessing tasks.
