PVDF Syringe Filters, 0.45um, 33mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18233

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18233

Featuring hydrophilic polyvinylidene fluoride membrane technology with 0.45 µm pore size, sterile packaging, and integrated polypropylene prefilter, these 33mm diameter filters deliver clarification performance for high-volume aqueous biological samples requiring particulate removal, rapid flow characteristics, and contamination-free processing across pharmaceutical manufacturing and biotechnology workflows without bacterial retention specifications. This configuration enables immediate processing of aqueous samples through naturally wettable surface chemistry that eliminates pre-treatment steps while maintaining low protein binding characteristics essential for biomolecule preservation. Meanwhile, the design with 4.9 cm² filtration area and 100 µL holdup volume maximizes recovery of valuable pharmaceutical formulations and biological materials for quality control and manufacturing applications processing volumes exceeding 100 ml.
