PTFE Syringe Filters, 1.0um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18182

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18182

Featuring hydrophobic PTFE membrane technology for coarse particulate removal in aggressive organic solvents and chemically challenging samples. A 1.0µm pore configuration delivers effective prefiltration while maintaining complete chemical inertness to concentrated acids, bases, and reactive reagents. Tisch Scientific combines ultra-resistant PTFE membranes with compact 13mm construction to provide efficient clarification of small-volume samples containing larger particulates and precipitates.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane requires alcohol pre-wetting for aqueous solution compatibility
• Universal chemical resistance withstands all organic solvents, acids, and bases without degradation
• Superior thermal stability maintains integrity at 60°C continuous operating temperature
• 1.0µm pore size provides effective coarse particulate and precipitate removal
• Autoclavable construction enables sterilization at 121°C for validated protocols

Key Construction Characteristics

• Polypropylene housing delivers chemical resistance while withstanding 87psi burst pressure
• Dual Luer-Lok/Luer Slip design accommodates all standard syringe configurations
• Compact 13mm diameter optimizes performance for small volume sample processing
• 10µl minimal holdup volume ensures maximum recovery of precious reagents

SF18182 syringe filters maintain 20ml/min flow rates through a 1.09cm² active membrane area, providing controlled prefiltration for your chemically aggressive samples containing coarse particulates. Minimal 10µl holdup volume maximizes your sample recovery while the compact design reduces solvent consumption during pre-wetting procedures. Autoclave compatibility at 121°C transforms nonsterile units into validated sterile filters, supporting your applications requiring both absolute chemical resistance and effective removal of larger particulates.

Hydrophobic

• Coarse prefiltration - Removal of precipitates, aggregates, and suspended solids from organic reaction mixtures before fine filtration
• Sample clarification - Initial filtration of crystallized products, catalyst particles, and visible contaminants in synthesis workflows
• Aggressive solvents - Prefiltration of THF, DMF, DMSO, chloroform, containing precipitated salts and reaction byproducts
• HPLC protection - Removal of larger particulates from samples before injection to prevent column inlet frit blockage
• Environmental analysis - Clarification of soil extracts and sediment samples in organic solvents for pesticide and pollutant testing
• Pharmaceutical prep - Removal of undissolved excipients and API aggregates from dissolution media and extraction solvents
