Using the CSS-450 Gas Purge and
Vertical Seal stage
Only refer to this page if you have purchased the CSS
-450 with additional gas purge / vertical seal option
Using the Purge ports
The vertical seal system allows the stage to be
used on its side whilst preventing any leakage. To
help remove or attach the lid to the stage, one of
these the vertical seal plugs (1) may need to be
removed to release the pressure inside the cham-
ber.
To apply gas purging to the stage, the vertical seal
plugs can be removed and replaced with the purge
adaptor tubes (2)
.
Once the adaptor tubes are in place, an external
supply can be connected to them to allow for the
purging procedure to commence.
Base Window Replacement
The procedure is the same as the one shown on
page 26 of this manual except that the window
clamping tool is slightly different.
The clamping tool for the CSS-450 purge / verti-
cal seal stage is shown on the right.
