Acro Disc Syringe Filters w/ PTFE Membrane - 0.2um, 25mm, 50/Pk SKU: 4225TC

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 25mm - 4225TC

Designed for the stringent demands of cell culture and biological assays, the Polytetrafluoroethylene (PTFE) Syringe Filters offers validated bacterial retention for confident sample preparation. Leveraging the specific retention properties of Polytetrafluoroethylene (PTFE), this device offers a validated 0.2 barrier against microbial contaminants. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

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
• 2.8cm² 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. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.
