Sterlitech PTFE Laminated Membrane Filters, 0.2 Micron, 13mm - 293mm

Laminated PTFE membrane filters are constructed from expanded polytetrafluoroethylene (ePTFE) with a durable polypropylene backing layer for improved handling and mechanical strength. These filters are inherently hydrophobic and chemically inert, making them ideal for use with aggressive solvents, strong acids, and gas filtration applications.

Key Features

Laminated ePTFE membrane for improved dimensional stability
Naturally hydrophobic and chemically resistant
Polypropylene backing for easier handling
Thermostable up to 260°C (500°F)
Uniform thickness and pore structure
Available in pore sizes from 0.1 to 1.0 µm

Enhanced Durability for Demanding Filtration Environments

The laminated design enhances the structural integrity of the membrane, making it easier to handle during installation and resistant to tearing. These membranes maintain the non-stick, inert qualities of unlaminated PTFE while being more suitable for demanding workflows such as pressure-driven filtration, phase separation, and venting in aggressive chemical environments. Their broad compatibility and high thermal resistance make them a trusted choice across laboratory, industrial, and OEM applications.

Filtration of strong acids and aggressive solutions
Venting applications
Phase separations
Aerosol samplings
Filtration of aqueous solutions (when prewetted with methanol)
