Safety Information
Safety Precautions
If the motor overloads - stop operation immediately.
If you continue operation under abnormal overload conditions, the motor may stop by the safety
device. If the motor stops, turn the volume knob to the minimum and cut the switch off.
Overload means the situatio n when the mo tor surfac e heats up more than 90
＊＊＊＊
rust on ball bearing etc.,
due to
℃℃℃℃
Make sure that the volume knob indicates “min” before turning the unit on.
Make sure that the volume knob is at “min”. If the volume knob is not turned to “min”, the
evaporation flask turns round when you turn on the power switch.
Move the lift up or down after you stop rotation of the evaporation flask.
If the lift is moved up or down while the evaporation flask is rotating, scalding may occur due to
dispersing of hot water. Be sure to move the lift after turning the volume knob to the minimum.
Never fail to ground the unit.
This unit uses a 3-core power cord (including ground wir e). Be sure to groun d the unit for safet y.
Be cautious using flammable chemicals.
This unit is not explos ion pr oof . Do no t use in f lamm able or exp losiv e gas en vironm ents and d o
not evaporate explosive substances.
The flask clamp is very springy. Be careful not to break the glass apparatus.
The enclosed flas k clamp is very springy to hold the glas s apparatus firmly. Be careful not to
break the glass.

Safety Information
Safety Precautions
Only water to be used with the Water Bath.
Only water in the W ater Bath. Probl ems can oc cur if anythi ng other than water is us ed. Also be
sure not to heat with low water level or the bath can overheat.
Use a trap.
Use a trap when you decom press by hydraul ic rotary vacuum pump. W hen you use our Hand y
Aspirator, fill to overflow.
Maintain the vacuum seal.
●
The vacuum seal is expendable. Exchange the seal in case of vacuum-down.
●
You can use the v acuum seal wit hout gre ase. B ut you desir e m ore longer lif e of the seal, put
silicon grease on to t he r ipped side of vac uum seal. If you are af r aid of s ample contaminat ion,
use liquid sample.
Cleaning the exterior of RE series evaporator
Do not use any volatile chem icals to clean the ext erior of th is unit. This could damage the color
and shape. Wipe clean with a soft dry towel , etc.-Do not use a brush.
If the unit is not in use for a long period of time, cut the power supply.
If the unit is not in use for a long period of time, turn the power off and pull out the power cord for
safety.

●
Combination with the vacuum controller VR100.
You can fix the vacuum controller, as shown in the
right picture, by metal fastener onto the controller
box of RE400/500 Rotary Evaporator.

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 determ ine 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 tub e ( ins ide di ameter 6mm) to the op en ing for sample and h and le t he c oc k 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.
