PTFE Membrane Filters - SF13853
Engineered for high retention efficiency and superior chemical stability, the Tisch SF13853 achieves reliable separation results across a broad range of analytical and preparative applications. Built for consistent results, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. In turn, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.
Material Specifications
- Permanently hydrophobic and chemically inert, PTFE resists degradation from virtually every solvent, acid, and base encountered in laboratory applications.
- Require pre-wetting with alcohol before filtering aqueous solutions.
- Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
- Unmatched solvent resistance allows PTFE to process chlorinated hydrocarbons, ketones, and strong oxidizers that destroy other membrane chemistries.
- Thermal stability of the membrane material allows safe operation at temperatures up to 120°C without degradation of retention characteristics or dimensional integrity.
Scaling from development to routine production requires membrane consistency at every lot, and the documented specifications provide the reproducibility needed to validate the filtration step once. For this application, PTFE's thermal stability across a wide operating range means you can filter hot solvents and process elevated-temperature samples without the membrane softening or pore distortion that limits thermoplastic alternatives. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
