Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18228

Pharmaceutical laboratories processing small-volume aqueous biological samples face workflow delays from membrane pre-wetting requirements and contamination risks during aseptic transfer procedures, requiring sterilization technology that enables immediate aqueous processing through naturally wettable surface chemistry while delivering validated bacterial retention with sterile packaging for contamination-free handling across cell culture media, buffer systems, and protein formulations. Hydrophilic polyvinylidene fluoride membrane technology with 0.22 µm pore size addresses this challenge through surface modification that eliminates alcohol pre-treatment steps while maintaining low protein binding characteristics. Additionally, the compact 13mm diameter design with 1.09 cm² filtration area and 10 µL holdup volume enables processing of 1-10 ml sample volumes, reducing preparation time for routine pharmaceutical workflows requiring both microbial control and efficient small-volume sample sterilization.

Key Hydrophilic PVDF Membrane Characteristics

Naturally wettable hydrophilic surface eliminates methanol or isopropanol pre-wetting steps, enabling immediate aqueous sample filtration without preparatory procedures
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 concentration of therapeutic proteins and biomolecules during sterilization, minimizing product loss in biopharmaceutical processing
Chemical compatibility resists degradation from biological buffers and aqueous solutions while maintaining stable operation across pharmaceutical formulation workflows
Sterile packaging eliminates initial contamination risks for aseptic transfer procedures, supporting GMP compliance requirements in pharmaceutical manufacturing facilities

Key Construction Characteristics

10 µL holdup volume optimizes yield by reducing sample retention within the housing, preserving valuable pharmaceutical formulations and biological compounds
Polypropylene housing 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 workflows
Integrated polypropylene prefilter with sterile packaging extends membrane lifetime while eliminating contamination risks for sensitive pharmaceutical sample processing
