Acro Disc PSF Syringe Filters w/ PTFE Membrane - 0.45um, 25mm, 1000/Pk SKU: AP-4501

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - AP-4501

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Syringe Filters is engineered to remove interfering solids efficiently. At the core of the device is a uniform Polytetrafluoroethylene (PTFE) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. 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
• Verified 0.45 retention rating for clarification

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. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. 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.
