PTFE Syringe Filters, 0.22 um, 30mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18322

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18322

Featuring hydrophobic PTFE membrane technology with 0.22µm pore size for reliable sterile filtration and bacteria removal from aggressive solvent systems. Large 30mm diameter filters deliver exceptional 29.5ml flow rates while maintaining complete microbial retention for high-volume applications. Polypropylene housing construction ensures robust performance at pressures up to 87psi across demanding laboratory protocols.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design provides sterile filtration of organic solvents, acids, and bases without degradation
• Sterile-grade 0.22µm pore size ensures complete removal of bacteria and microorganisms for aseptic processing
• Superior chemical resistance from strong carbon-fluorine bonds withstands aggressive solvents and reagents
• Membrane thickness of 80-140µm optimizes flow characteristics while maintaining sterility assurance levels
• Autoclavable at 121°C for 30 minutes or gamma sterilizable at 25kGy for validated sterile applications

Key Construction Characteristics

• Polypropylene housing provides broad chemical compatibility with organic and inorganic solvent systems
• Large 30mm diameter with 4.9cm² filtration area enables rapid processing of high-volume samples
• Holdup volume of 100µl minimizes sample loss while maintaining practical handling for routine applications
• Luer-Lok/Luer Slip dual connection system ensures secure attachment to various syringe sizes

SF18322 filters maximize your sterile filtration efficiency with an impressive 29.5ml flow rate, significantly reducing processing time for large-volume samples. The maximum operating temperature of 60°C accommodates warm solvent filtration while the 120ml volume throughput capacity handles multiple preparations per filter. Bubble point verification at 17.4psi using absolute ethyl alcohol confirms membrane integrity for your critical sterile filtration requirements.
