8. Bubbler
Once the vacuum has been done 5 times (remembering to reinsert inert gas between each):
① Remove the vacuum pump flexible air hose from the outlet flange. Then, connect the bubbler to the
outlet flange with the o-ring (may need grease). Remember to keep the inlet and outlet valves closed when
doing this.
② Seal the connection by closing the clamp slightly.
③ Fill the bubbler with 70 mL of water (level at 110 mm height from the bottom).
④ Slowly open the outlet valve (let the overpressure released to 0 bar) and set the flowmeter to 0.5 L/min
(or according to the filament guideline).
⑤ Set the heat treatment, during it:
-
Adjust the water level to 110 mm every 48 hours to compensate the evaporation.
-
Inlet and outlet flange must be kept opened.
-
Stop the furnace (hold or stop states) if the pressure is higher than 0.2 bar (0.02 MPa) and/or the bubbler
is not bubbling.

Maintenance
