Acro Disc PSF Syringe Filters w/ PTFE Membrane - 0.2um, 25mm, 200/Pk SKU: AP-4225

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

Eliminate the risk of microbial contamination in your upstream workflows with the Polytetrafluoroethylene (PTFE) Syringe Filters, optimized for sterile filtration protocols. Central to this performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

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. Protecting your downstream processes requires a defensive strategy, and utilizing these verified filters gives you the peace of mind that your work is safe. 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.
