Ultradyne® PTFE Membrane (Hydrophobic)

PTFE membrane filters providing the utmost assurance of chemical resistance, durability and critical filtration performance in aggressive fluids.

Ultradyne® absolute-rated polytetrafluoroethylene (PTFE) membrane filters offer the highest level of assurance of chemical compatibility and filtration performance in aggressive chemicals, prolonged hot air service and other severe process conditions. Ultradyne® filters’ PTFE membrane delivers superior flow rates and long service life. The highly porous membrane is inherently hydrophobic and offers maximum chemical compatibility with minimal extractables in a wide range of fluids and applications. Support components are all-polypropylene.

  • Ultraclean – no additives, surfactants or post-treatments
  • Inherently hydrophobic PTFE membrane
  • Wide chemical compatibility
  • Extended service life in sterilizing hot compressed air
  • Minimal extractables levels
  • 100% integrity tested
  • Cleanroom manufactured

Ultradyne® meets the critical demand for contamination control in the chemical, microelectronics, aerospace, biologicals, pharmaceuticals, food and beverage, and other industries. The Ultradyne® cartridge is designed for the removal of particulates, colloids and microorganisms from aggressive solvents, highly corrosive chemicals and gases. It is ideal for bulk and point-of-use filtration. Typical chemicals include:

  • Highly concentrated acids
  • Bases
  • Alcohols
  • Chlorinated and fluorinated solvents
  • Esters
  • Ketones
  • Photoresists
  • Etchants
  • Photolithographic solutions

For aqueous solutions, the Ultradyne® filter must be pre-wet by immersion in a suitable low surface tension fluid. The inherently hydrophobic Ultradyne® filter is ideal for gas filtration applications that include:

  • Compressed air
  • Fermentation air
  • Pressurized gases
  • Tank venting
