5.6.2 Condensation of the vapours upstream of the vacuum pump in a cooling
trap
The vapours are condensed upstream of the vacuum pump in a cooling
trap, e.g.”CT 02-50” or “CT 04-50”.
The application is suitable for water-base, low-boiling samples containing
solvents. The RVC, the cooling trap and the vacuum pump must be
connected. The connector of the stop valve must be plugged into the
socket on the back of the unit.

Attention: The set-up in the photo is for demonstration purposes only! Normally, the stop
valve is installed behind the rotational vacuum concentrator and cannot be seen from the
front.

5.6.2.1 Option: Remote control of the cooling trap via RVC
If CHRIST freeze dryers are used as a cooling trap, they can be remote-
controlled by the rotational vacuum concentrator. In this case, the cooling
trap will be automatically activated by the rotational vacuum concentrator
during the warm-up and evaporation phase. In the standby mode, the
cooling trap will be either switched off or continue operation, depending on
the choosen option (chapter 6.5.3.5 - "Options" Settings / Continuous
operation coldtrap"). The ice condenser temperature is indicated in the
values window of the rotational vacuum concentrator.
The cooling trap must be connected to the rotational vacuum concentrator
with the aid of a zero cross cable (part no. 222 000). In addition, the option
"Cooling trap control" must be activated (see chapter 6.5.3.5 - "Options").
