3.7 Inert gas cover / inert gas module
Using the inert gas cover, 24 reaction glass vessels can be
simultaneously sealed against the environmental tempera-
ture and they can be gassed with an inert gas. As a result,
24 chemical reactions can be carried out at the same time
under inert gas (for example water exclusion via Argon).
Reagents can be added through individual septa in the
inert gas cover or samples can be removed from the test
tubes.
The tubes for adding and removing inert gas are secured
by means of tube safeties as illustrated a.
It is not important which connection on inert gas connec-
tion or inert gas module is used for adding or removing
inert gas.
The vacuum connection can be sealed with the SVL22
screw cap b.
An inert gas module is used together with a vacuum cover.
For this purpose, the glass plate c of a vacuum cover in
format 24 is removed by loosening the two screws d and
the two seals e.
The inert gas module is placed on the bottom of the va-
cuum cover in place of the glass plate. The two seals e
are inserted as illustrated and the inert gas module is fixed
with the two screws d. The PEEK septa screw joints are
to point upward as represented.
The component cannot be used without secured tube
connection. All tube connections must be oriented away
from users.
