Permeation Tubes (3526)

Fri, 04/04/2008 - 5:01am


Trace Source Permeation Tubes are small Teflon tubes filled with pure component compound. These tubes emit a small, stable flow of pure component for making low concentration (ppm and ppb) gas mixtures. The flow is measured in nanograms or nanoliters per minute. Each tube has a serial number and is laboratory certified. The emission rate of the permeation tube is varied by changing the temperature of the tube. There are permeation tubes for more than 400 chemical compounds. Tubes are available in many selections such as disposable permeation tubes, refillable permeation tubes, refillable gas fed tubes, and extended life permeation tubes. The type of tube needed may be determined by the chemical compound and the mixture concentrations requested.
