Polytetrafluoroethylene (PTFE) Syringe Filters - SF18248

When you need to protect expensive downstream filters from coarse particles in aggressive solvents, you need broad chemical resistance and high throughput. These 3.0µm PTFE filters handle strong acids, bases, and halogenated organics while removing large particulates that would clog fine membranes. The large 33mm diameter with 8.55cm² filtration area processes high-volume samples efficiently, and pre-sterilized packaging means contamination-free handling. Polypropylene housing withstands pressures up to 87psi across demanding chemical applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively prefilters organic solvents, acids, and bases without chemical degradation
• Coarse 3.0µm pore size removes large particles, aggregates, and visible contaminants from bulk solutions
• Pre-sterilized by gamma irradiation ensures contamination-free handling for critical laboratory applications
• Broad chemical resistance from strong carbon-fluorine bonds maintains membrane integrity in aggressive solvents
• Membrane thickness of 80-140µm provides an optimal balance between flow rate and particle retention efficiency

Key Construction Characteristics

• Polypropylene housing ensures broad chemical compatibility with organic and inorganic solvent systems
• Large 33mm diameter provides 8.55cm² filtration area for 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 design accommodates various syringe sizes and automated systems

Pre-sterilized packaging means you can start filtering immediately without autoclaving preparation, important when processing multiple sample batches. The large 8.55cm² filtration area provides high throughput for bulk samples, and the coarse pore structure handles particulate-laden solutions that would quickly clog finer membranes. Process samples at temperatures up to 60°C without membrane degradation, and the 2.9psi bubble point confirms consistent pore structure across production lots.

Hydrophobic

• High-Volume Prefiltration - Removes coarse particles from bulk solvents and process streams, protecting expensive 0.22µm filters from premature clogging
• Industrial Sample Clarification - Prefilters process samples and reaction mixtures in pharmaceutical manufacturing, where high throughput is required
• Catalyst Removal - Eliminates heterogeneous catalyst particles from organic synthesis reactions where aggressive solvents require chemical resistance
• Environmental Testing Preparation - Clarifies heavily contaminated water and soil extracts before fine filtration in regulatory compliance testing
• Pharmaceutical Dissolution Testing - Removes undissolved excipients and tablet fragments during quality control dissolution studies for drug products
• Viscous Media Processing - Prefilters high-viscosity oils, polymers, and concentrated solutions that would rapidly clog fine membranes in downstream steps
