Polytetrafluoroethylene (PTFE) Membrane Filters, 2.0µm, 47mm - SPEC20238

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Membrane Filters is engineered to remove interfering solids efficiently. Facilitating rapid sample turnover, the hydrophobic Polytetrafluoroethylene (PTFE) membrane structure ensures the 2.0 rating remains consistent even under pressure. Delivered as precision-cut discs, these membranes ensure compatibility with all standard filter holders and funnels. 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 2.0 retention rating for clarification

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. 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.
