Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 25mm - AP-4791

For critical applications requiring absolute sterility assurance, the Polytetrafluoroethylene (PTFE) Syringe Filters series provides a verified barrier against bacterial contamination. Driving this efficiency is the integration of a hydrophobic Polytetrafluoroethylene (PTFE) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (PTFE) membrane with hydrophobic (standard) / hydrophilic (treated) affinity
• Chemically Inert characteristics
• Universal resistance to aggressive organic solvents, strong acids, and alkalis
• Hydrophobic version requires alcohol pre-wetting for aqueous solutions
• 0.2 rating suitable for sterile filtration

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Luer Slip for secure fitting
• 3.9cm² effective filtration area
• < 100 µl holdup volume to minimize sample loss

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
