Permeation Tubes

Permeation tubes are devices used to produce a steady, precise release of a specific gas or vapor over time. They contain a liquid or solid substance that slowly diffuses through a permeable material, releasing a consistent amount of the substance. These tubes are commonly used in calibration, environmental testing, and research to generate accurate gas standards. By providing a reliable and uniform emission rate, permeation tubes help ensure precise measurements and analyses in various scientific and industrial applications.
