Sterile Hydrophilic PVDF Syringe Filter 33mm 0.22/0.45um 50-500Pcs Lab Bio
Maximize your laboratory's processing capabilities with our high-capacity, sterile Hydrophilic PVDF Syringe Filters. Engineered with an expanded 33mm diameter for processing large 100-200 mL volumes, these filters are sterilized via gamma radiation and individually blister-packed to ensure absolute purity. Featuring ultra-low protein binding and broad chemical compatibility, they are the premier choice for rapidly processing aqueous solutions, mild organic solvents, and delicate tissue culture media without requiring pre-wetting.
Available Variations
Pore Size 0.22 μm: Optimal for sterilizing filtration, complete bacteria removal, and ultra-critical biological sample preparations.
Pore Size 0.45 μm: Perfect for sterile clarification, macro-particulate clearance, and routine sterile media preparation.
Quantity 50 Pcs: Standard lab use, individually packed.
Quantity 100 Pcs: Ideal for regular sterile processing workflows.
Quantity 300 Pcs: Bulk pack for continuous, high-volume laboratory workflows.
Quantity 500 Pcs: Maximum value for high-demand research and testing facilities.
Key Features & Benefits
Guaranteed Sterility: Sterilized by gamma radiation and individually packed to maintain absolute sterility right up to the moment of use, completely eliminating cross-contamination risks.
High-Volume Processing: The large 33mm diameter provides an expanded 4.5 cm² effective filtration area, ensuring rapid and smooth processing of 100-200 mL liquid samples without premature clogging.
Ultra-Low Protein Binding: The hydrophilic PVDF membrane maximizes the recovery of valuable proteins, making it highly suitable for biological, clinical, and tissue culture fluid filtration.
Robust & Leak-Free Construction: Safely housed in a medical-grade Polypropylene (PP) casing that withstands maximum operating pressures up to 5 bar.
Standardized Fittings: Designed with a Female Luer Lock inlet and Male Slip Luer outlet for quick, secure, and leak-free attachment to all standard laboratory syringes.
