Aluminum alloys are used to construct standard permeation tubes and are compatible with many gases, liquifiable gases and liquids. Teflon™ is used for chlorine.
SPECIAL PERMEATION TUBES (NON-STANDARD)
Permeation tubes are designed as "Special" when they are of non-standard specifications. These special tubes may be:
* Constructed from materials other than aluminum,
* Constructed in sizes other than those shown above,
* Have unusual
features, such as different size thread, and/or
* Used to permeate unusual
chemicals.
Because of these special requirements, quality control
tests may extend date of delivery. Call for further information about special
orders.
