Stage: Development

The Extrans permeation measurement system is a customizable system for testing the behavior and uniformity of polymers and other materials. The system can be used to determine permeation rates using variable temperatures, total pressures, differential pressures, and mechanical deformations as well as adjustable concentration levels for gases and liquids. Extrans supports permeation testing from liquid-to-gas or from gas-to-gas phases.
