How do I select the material of the outer tube?

A silica tube is recommended for use at temperatures below 900 deg. C. It can also be used at 1000 deg. C for short time. We can however not guarantee gas tightness of the silica tube after using it at high temperature. Above 900 deg. C we recommend to use alumina outer tubes. For high-pressure measurements a SS protection tube should be used either alone or together with an alumina outer tube.
