Preparation and Operation Method
5. Pour cooling water/alcohol into the cooling tube..
● In case of Glass A or B
Circulate the cooling water in the connected cooling tube.
● In case of Glass C
Uncover the cooling tube lid, put dry ice and pour alcohol carefully so that it wouldn’t overflow.
6. Put sample into the distilling flask.
After you put sample into the distilling flask, sink the flask quietly into the bath which contains water
by the hand lift, and determine the level.
＊ ＊ ＊ ＊Pour sample to the half of the distilling flask capacity. Liquid collected in the receiver flask
shall be also kept within approximately the half capacity.
7. Heat the bath.
Set the bath temperature at the required degree and heat up to the set point.
8. Turn on the power switch and start operation.
When the bath temperature reaches the set point, turn on the switch on the right side of control box,
and handle the volume knob to rotate at a certain frequency. Operate the vacuum device for
distillation.
＊ ＊ ＊ ＊ When the operation ends and you want to finish the work, open the cock and bring back
pressure inside the container to normal. To take out the distilling flask from the water
bath, turn the volume knob to “min”, and be sure to turn the switch “OFF”. Never fail to
take away sample inside the distilling flask after the operation ends.
●When you supply sample during the operation...
In order to supply sample into the distilling flask, connect the teflon tube (inside diameter, 6mm) to
the sample injection pipe and handle the cock to let a certain amount sucked in.
