4. OPERATION PROCEDURES
1. Cooling Condenser
●
Condenser type A and B:
Circulate water or alcohol through the cooling condenser, using Yamato Scientific CF model cooling
circulators or other applicable device.
●
Condenser type C
Fill with dry ice or alcohol.
2. Evaporation Flask
Fill flask with process sample fluid.
＊
Do NOT fill evaporation flask to more than half capacity. Fluid collected in the receiving flask should
also be kept within half capacity.
3. Water Bath
Set temperature as required. Allow bath to reach temperature setting and stabilize.
4. Position flask and start operation.
1. When the bath stabilizes at temperature setting, adjust height (see P.14 & 15) to maneuver evaporation
flask down and into the bath.
2. Turn main power switch on the right side of control box to ON, and rotate the control dial until desired
speed is reached.
3. Turn on vacuum device (if required) to accelerate evaporation process.
●
Process Sample Feed
Sample fluid may be fed during operation without having to remove evaporation flask.
1. Connect an appropriate teflon tube to the sample feed inlet (id=6mm).
2. Slowly rotate the feed stopcock handle. Sample fluid is drawn into the flask.
Stop flask rotation before lifting flask out of bath. Rotating flask out of bath may spin off
hot water, possibly causing scalding injuries.
5. Operation end
When process has finished as desired, repressurize (stop vacuum) by opening the feed stopcock before
turning off the vacuum pump and removing the evaporation or receiving flasks.
Power Failures
Unit will restart when power is restored. If unit is to be unattended while power failure is in progress, turn off
all power switches related to RE unit operation.
