5. How To Operate
1. Pour cooling water/alcohol into the cooling condenser.
● In case of glass A or B
Circulate the cooling water in the cooling condenser.
●In case of glass C
Put dry ice and pour alcohol carefully so that it does not overflow.
2. Put sample into the evaporation flask.
Put sample into the evaporation flask.
＊ ＊ ＊ ＊Pour sample to fill the half of the evaporation flask capacity. Liquid collected in the
receiving flask shall be also kept within approximately the half level.
3.Heat the bath.
Set the bath temperature at the required degree and heat up to the set point.
4. Turn the power on, and operate the lift.
1.When the bath temperature reaches the set point, make sure that the volume knob stays at “min”,
and turn on the power switch on the right side of control box.
＊ ＊ ＊ ＊ If, at this time, the volume knob is not at “min”, the evaporation flask rotates when you
turn the power on.
2.Operate the lift switch to put the evaporation flask gently into water bath, and determine the
adequate operational position.
5. Start rotation
Set the volume knob at the required speed to rotate. Operate the vacuum device as well for
evaporation.
● ● ● ●When you supply sample during the unit operating
Connect the teflon tube (inside diameter 6mm) to the opening for sample and handle the cock to
let certain amount sucked in.
6. Move the lift up or down after you stop rotation of the evaporation flask.
If the lift is moved up from or down into the bath while the evaporation flask is
rotating, scalding may occur due to dispersing of hot water.
7. When the operation ends
When the operation ends and you want to remove the evaporation or receiving flask , open the cock
and bring back pressure inside the container to normal.
8. Operation after restarting from power failure.
The unit restarts the same operation as before after recovering from power failure.
