PES Membrane: Memtrex MP Filter

Memtrex MP pleated cartridge filters combine absolute-rated hydrophilic polyethersulfone (PES) membranes with polypropylene components, delivering superior particle retention at high flow rates. These filters feature extremely low protein-binding characteristics and broad chemical/pH compatibility, making them ideal for beverage, chemical, and pharmaceutical applications. The asymmetric PES layer delivers low pressure drops with high throughputs and broad particle capture. Thermally welded without adhesives or additives, and individually integrity tested, these USA-made filters come standard with polypropylene adapters. For steam or autoclave sterilization, steel adapter rings are required. Alternatively, the filters can be sanitized with compatible chemical agents using the standard polypropylene adapters.

PTFE Membrane: Memtrex FE Filter

Memtrex FE filters feature absolute-rated Polytetrafluorethylene (PTFE) membrane cartridges that excel in diverse fluid and gas applications. These filters are characterized by their exceptional chemical resistance and minimal extractables. The hydrophobic nature of the PTFE membrane makes them particularly effective for filtering compressed air and process gases. Manufactured in clean-room conditions using thermal welding, these filters are free from adhesives and additives. Quality is ensured through individual integrity testing of all subassemblies. Key benefits include strong resistance to aggressive substances, wide chemical compatibility, consistent particle capture in harsh environments.

Industries and Applications

• Aggressive solvents, such as alcohols, esters and ketones 
• Corrosive acids and bases 
• Vents/exhausts for autoclaves, fermenters, and storage tanks 
• High purity chemicals and water used in electronics manufacturing
