5. How To Operate
1. Cooling condenser
●Glass A or B
Circulate the cooling water or alcohol in the cooling condenser.
●Glass C
Put dry ice and pour alcohol carefully so that it does not overflow.
2. Evaporation flask
Put sample into the evaporation flask.
＊ ＊ ＊ ＊Fill evaporation flask to the half of it’s capacity. Liquid collected in the receiving flask
should also be kept within approximately half capacity.
3.Water bath
Set the bath temperature at the required degree and let heat to the set point.
4. Turn the power on, and move flask down.
1. When the bath temperature reaches the set point, make sure that the control 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 move the evaporation flask gently into water bath, and determine the
adequate operational position.
5. Start rotation.
Set the control knob at the required speed to rotate. Operate the vacuum device as well for
evaporation.
● ● ● ●S SS Sample Feed
Sample may be fed during operation without removing the evaporation flask.
1. Connect a teflon tube to the inlet feed cock.(id=6mm)
2. Slowly move the fed cock handle. Sample will be sucked into the flask.
6. Moving lift position
Stop rotation of motor before moving the lift. Scalding may occur due to dispersing
of
hot water.
7. End of operation
When the operation ends and you want to remove the evaporation or receiving flask , open the feed
cock to release vacuum.
8. Power failure.
The unit restarts operation once power is restored.
