For sensitive reactions where traces of steam or other ga-
ses can cause disturbances, we recommend the following
procedure to efficiently exchange the atmosphere by an
inert gas:
1. Lock the inert gas inlet a and outlet b on the inert gas
module using a clamp bride or a 3-way faucet.
2. Evacuate the Syncore to 300 mbar.
3. Ventilate the system with inert gas via the Vacuum
Controller (connect the ventilation valve to the inert gas
main).
4. Repeat steps 2 and 3 three times.
5. Open the inert gas inlet a and then outlet b at the inert
gas module.
6. Set the light inert gas flow to c. 1 to 2 bubbles/se-
cond.
