Overview

Expanded polytetrafluoroethylene (ePTFE) membrane

GORE Microfiltration Media products offer an excellent combination of high flow rates and reliable retention of aerosols and particles, making them a top choice for filtration and venting in pharmaceutical, biopharmaceutical, lab and analytical, food and beverage, and industrial biotechnology applications. GORE Microfiltration Media meets the needs of the most demanding gas and solvent filtration and venting applications, thus delivering increased process security. These products set the standard for quality, consistency, and performance.

GORE Microfiltration Media products incorporate a proprietary expanded polytetrafluoroethylene (ePTFE) membrane that is resistant to high temperatures and a broad range of chemicals. The unique structure of the membrane consists of billions of continuous, interconnected fibrils and nodes. This robust membrane design allows for optimal particle retention and increased performance in critical microfiltration applications.
