PTFE Membrane Filters (w/out Substrate), 5.00 um, 47mm, Nonsterile, 100/Pk SKU: SF18114

Polytetrafluoroethylene (PTFE) Membrane Filters, 5.0µm, 47mm - SF18114

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Membrane Filters deliver exceptional retention of particulates without compromising flow rates. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 5.0 cutoff that passes only your target analyte. 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

Wetability

Hydrophobic

• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• Cryogenic Fluids - Delivers consistent performance in extreme temperature environments, filtering cryogenic liquids with exceptional reliability
• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
