PTFE Syringe Filters, 0.1um, 33mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18086

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18086

Featuring advanced hydrophobic PTFE membrane technology engineered for exceptional chemical resistance and fine particulate removal at 0.1µm pore size. High-capacity 33mm diameter filters deliver reliable performance for demanding laboratory applications requiring ultrafine filtration with minimal sample loss. Robust polypropylene housing construction ensures compatibility with aggressive solvents while maintaining structural integrity at pressures up to 87psi.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design repels aqueous solutions while effectively filtering organic solvents and gases
• Exceptional chemical resistance to acids, bases, and aggressive organic solvents due to strong carbon-fluorine bonds
• Ultra-fine 0.1µm pore size removes small particles, microorganisms, and submicron contaminants
• Membrane thickness of 80-140µm provides optimal flow rates while maintaining filtration efficiency
• Autoclavable at 121°C for 30 minutes or gamma sterilizable at 25kGy for sterile applications

Key Construction Characteristics

SF18086 filters combine ultra-fine 0.1µm filtration with high chemical resistance to deliver consistent results in your most demanding applications. A flow rate of 12ml through the 33mm membrane ensures efficient processing while the 120ml volume throughput capacity handles multiple samples without replacement. Maximum operating temperature of 60°C accommodates warm solvent filtration, expanding your analytical capabilities across diverse laboratory protocols.

Hydrophobic

• Fine Particulate Removal - Eliminates particles down to 0.1µm from organic solvents, ensuring ultra-clean filtrates for sensitive analytical methods
• Submicron Filtration - Removes viruses, mycoplasma, and small microorganisms from non-aqueous samples in pharmaceutical and biotechnology applications
• HPLC Sample Preparation - Protects expensive analytical columns from particulate contamination while maintaining sample integrity for accurate results
• Organic Solvent Clarification - Filters aggressive chemicals, aromatics, and halogenated solvents without membrane degradation or extractables
• Gas Filtration - Hydrophobic properties provide reliable venting and gas phase filtration for fermenters, bioreactors, and sterile gas applications
• Protein Precipitation Cleanup - Clarifies samples after protein removal in organic solvents, ideal for proteomics and bioanalytical sample preparation
