Setting the lower end stop
Depending on the size of the piston,
CAUTION
the setting angle of the rotation drive
and the position of the heating bath
and lift, the evaporation flask can be in
contact with the bottom of the heating
bath.
Glass may break!
CAUTION
Limit the lower lift position with the variable end stop.
The lift can be moved to any desired position in manual mode
using the "" and "" keys. There is no automatic cut-off if a
collision occurs.
• Press the "" key until the lift reaches the desired position.
Note: The evaporation flask should be 2/3 immersed in the hea-
ting bath.
• To adjust the stop element (1), press the center button (2) on
the front of the lift.
• Move the stop (1) to the desired position
• Press the "" key until the lift has reached the upper end stop.
Note: The path is limited from 0 – 6 cm.
Fill the evaporation flask
Manual filling: You can fill the evaporation flask manually prior
to creating the vacuum. The evaporation flask should not be filled
more than half its volume.
Automatic filling: Prior to filling the evaporation flask, a vacuum
controller is used to regulate the glass apparatus to the target
pressure.
• Now fill the evaporation flask using the back feed line.
• Due to the vacuum present, the solvent is suctioned into the
evaporation flask. This enables you to keep solvent loss due to
suctioning to a minimum.
The maximum allowed load (evapora-
CAUTION
tion flask and contents) is 3 kg.
Setting up the heating bath
Refer to the operating instructions
CAUTION
for the heating bath IKA HB!
• Move the lift to the bottom position and check the position
of the heating bath in relation to the evaporation flask. When
using larger evaporation flasks (2 or 3 litres) or depending on
the angle of the rotation drive, you can move the heating bath
50 mm to the right.
• Fill the heating bath with the tempering medium until the eva-
poration flask is surrounded by tempering medium to 2/3 of its
volume.
• Switch on the rotation drive and slowly increase the speed
Note: Avoid creating waves.
• Switch on the heating bath using the main on/off switch.

Check that the limit stop is functioning properly:
• Lower the lift by holding down the "" key.
• The drive stops automatically when the preset desired lower
end position has been reached.
• Move the drive back to the upper position.
To activate the safety lift following a long period of inactivity, use
the motor to move the lift to the top or bottom position several
times prior to starting the distillation. (See the section entitled Sa-
fety Instructions - Safety Lift)!
Note: Avoid stress on the glass due to different evaporation flask
and heating bath temperatures when lowering the evaporation
flask into the heating bath!
Note: If non-original accessories are used that are not supplied
by IKA, then it is possible that the 50 mm travel range provided
by the heating bath will not be sufficient. This applies in particular
when using 3 L evaporator flasks with foam brake.
Use the IKA RV 10.3000 extension plate to extend the heating
bath travel range by 150 mm.
