After required evacuating time,
► position the upper valve ( V 3) slowly to N2 .
→ The flask will be flooded with nitrogen.
► Let the valve in the position N2 for ca. 2 sec.
(the required time is also dependend on
the volume of the flask).
► Evacuating and flooding (step 1 - 4) has to be carried out
at least 3-fold. *)
