PTFE Membrane Filters, 0.45um, 50mm, Nonsterile, 100/Pk SKU: SF14685

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 50mm - SF14685

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45um, 50mm, Nonsterile, 100/pk delivers exceptional retention of particulates without compromising flow rates. At the core of the device is a uniform Polytetrafluoroethylene (PTFE) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Delivered as precision-cut discs, these membranes ensure compatibility with all standard filter holders and funnels. 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
• Verified 0.45 retention rating for clarification

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
