PVDF Syringe Filters, 0.22um, 33mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18230

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18230

Precision 0.22 µm hydrophilic polyvinylidene fluoride membrane technology with sterile packaging and integrated polypropylene prefilter delivers validated bacterial retention for high-volume aqueous biological samples requiring immediate wettability, rapid flow characteristics, and contamination-free aseptic processing across pharmaceutical manufacturing and biotechnology workflows. This configuration combines naturally wettable surface chemistry that eliminates pre-treatment steps with 4.9 cm² filtration area and 33mm diameter design, enabling efficient sterilization of volumes exceeding 100 ml while maintaining low protein binding characteristics essential for therapeutic protein manufacturing. Meanwhile, the dual-layer construction with 100 µL holdup volume preserves samples by reducing retention within the housing, making this filter ideal for biopharmaceutical production and quality control applications demanding both microbial elimination and efficient aqueous sample processing with sterile handling capabilities.

Key Hydrophilic PVDF Membrane Characteristics

Naturally wettable hydrophilic surface eliminates alcohol pre-wetting requirements, enabling immediate aqueous sample filtration without preparatory solvent steps or workflow delays
0.22 µm pore size provides sterile-grade filtration with validated bacterial retention, including Brevundimonas diminuta, ensuring microbial elimination for pharmaceutical manufacturing
Low protein binding characteristics maintain the concentration of therapeutic proteins and enzymes during sterilization, minimizing product loss in biopharmaceutical applications
Chemical compatibility resists degradation from biological buffers and mild acids while maintaining stable operation across pharmaceutical formulation environments
Sterile packaging eliminates initial contamination risks for aseptic processing, supporting GMP manufacturing requirements in pharmaceutical production facilities

Key Construction Characteristics

100 µL holdup volume optimizes yield by minimizing sample retention within the filter housing, preserving valuable pharmaceutical formulations and biological materials
Polypropylene housing construction delivers structural integrity to 87 psi maximum operating pressure with thermal stability to 60°C for diverse bioprocessing conditions
Dual Luer-Lok and Luer-Slip connections accommodate standard syringes without adapters, streamlining aseptic transfer procedures in pharmaceutical manufacturing workflows
Integrated polypropylene prefilter with sterile packaging extends membrane lifetime while eliminating contamination risks for high-volume cell culture applications
