Polypropylene Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18216

Polypropylene (PP) Syringe Filters - SF18216

Contamination risks in sterile pharmaceutical workflows demand absolute bacterial retention without compromising sample integrity or introducing extractables that interfere with analytical precision. Traditional sterile filtration often sacrifices economy for performance, creating budget constraints in routine quality control and research applications. Gamma-sterilized polypropylene membrane technology at 0.22µm eliminates these compromises through economical construction that delivers reliable bacterial removal with hydrophobic characteristics requiring minimal preparation. Technical capabilities include validated 14.50psi bubble point ensuring consistent 0.22µm retention, 25mm platform with 4.08cm² filtration area, and 100µL holdup volume supporting 18ml flow rate with 50ml throughput capacity for cost-effective sterile processing.

Key Polypropylene Membrane Characteristics

Sterile-grade 0.22µm pore structure provides validated bacterial retention for pharmaceutical and biological applications requiring absolute contamination control
Hydrophobic membrane architecture necessitates pre-wetting with a compatible organic solvent before aqueous filtration, establishing continuous flow pathways through the membrane matrix
Cost-effective platform delivers economical sterile filtration alternative for routine laboratory workflows while maintaining dependable performance across compatible chemical environments
Selective solvent compatibility accommodates acids, bases, and aqueous solutions following proper pre-wetting while avoiding esters that compromise membrane integrity
Low extractables profile minimizes interference in analytical workflows where sample purity directly impacts measurement accuracy and method validation

Key Construction Characteristics

Optimized 100µL holdup volume minimizes loss of valuable samples during 10-100ml processing, where recovery efficiency impacts both economics and analytical results
Moderate-temperature polypropylene housing maintains structural integrity up to 60°C maximum operating temperature for ambient and slightly elevated processing conditions
Dual Luer-Lok/Luer Slip interface provides flexibility with standard laboratory syringes, enabling quick connections without specialized adapters or workflow modifications
Robust 4.08cm² filtration area balances throughput efficiency with 18ml flow rate performance at 87psi maximum operating pressure for demanding applications

Built to support your cost-conscious sterile processing requirements, gamma-sterilized polypropylene construction delivers dependable bacterial retention. Validated 14.50psi bubble point ensures operational confidence throughout pharmaceutical workflows. Moderate holdup design combined with flexible Luer connectivity maintains your laboratory efficiency across diverse applications requiring economical yet reliable sterile-grade filtration performance.
