Manual for Rotary Evaporator
Introduction of usage
Rotary evaporator is a kind of device with the operation principle as follows:
put the rotary evaporation bottle (flask used to increase the evaporation
area) in water bath under the condition of reduced pressure, and make it
rotate while heating it, so as to make the solution in the bottle diffuse and
evaporate. It is a relatively ideal basic instrument necessary for the
concentration, drying and recycling relied on by the production and
experimental analysis which is conducted by the chemical industry,
pharmaceutical industry, universities and colleges, and research laboratories
and so on.
Structural features
-
Rotation of principal machine
The principal machine consists of a group of reliable micro-motors ,speed motors and integrated circuits. Under the action of electronic speed control, it can realize the stepless speed regulation within the range of 0-150 r / min. -
Elevation of principal machine
RE-52AA-type principal machine adopting the method of micro-motor speed change can be automatically ascended and descended only by pressing the switch with hand. The elevation is
stable, safe and reliable. -
Tilt of principal machine
The principal machine can be tilted at random within the range of 0-45 ° by loosing plum blossom screws. The condensate system made of heat-resistant high-quality glass is connected to the head of principal machine with sockets, thus making it able to tilt therewith and continuously feed. -
Heating water tank
Heating water tank is equipped with a closed heating tube with heating wire, and connected to digital display of temperature, which can automatically connect or disconnect the power so as to automatically control the water temperature inside the tank. -
Evaporation pipe
Evaporation pipe uses PTFE, which is corrosion-resistant and can maintain a high vacuum. -
Cooler (made of high-quality glass of thermostability, and refined) Vertical, Dual-reflux.
-
Main metal components are made of corrosion-resistant high-quality stainless steel, thus extending the service life.
Matters needing attention for use
-
Please read the Manual and Brief Introduction of Installing Rotary Evaporator first, and focus on the part of installation preparation, installation procedures and operation.
-
As for the expensive solution, a simulation technology experiment should be conducted first. Then, the solution can be normally used after confirming the equipment can meet the experimental requirements.
-
Water temperature inside the water tank will be automatically controlled by the digital display of temperature.
Accurate water temperature will be measured directly through the mercury thermometer. -
In case of needing to replace the fuse, the power should be cut off first, followed by the opening of cover to replace the fuse.
-
When heating the water tank, do not touch with hand to prevent the scald.
-
Can not be used under the environment full of flammable, explosive and narcotic gas.
-
In general, this product does not have specific requirements for disinfection.

|
- Insert the power plug tight
- Replace the fuse
Rotation bottle shakes or gives out noise when
rotating
| Check whether the glass interface of rotation bottle is installed smoothly and in place| Reinstall the glass interface and rotation bottle, and screw and lock the nut tightly.
Insufficient vacuum
|
- Check the performance of vacuum pump, and whether each connector is tightened (block the air outlet of vacuum pump to observe the indicators on vacuum table
- Check whether the glass appliances are defected or cracked for coldness
- Check whether the interface of glass appliance is coated with vacuum grease
|
- Screw the connectors tightly or replace the vacuum pump Replace the damaged appliances
- Recoat with vacuum grease
Water tank can not be heated.|
- Check the 10A fuse
- Check whether the heating plug is loose
|
- Replace the 10A fuse
- Insert the heating plug tightly
In case of being unable to troubleshoot according to the above methods, contact us by calling
Storage and transportation
Instruments packed should be stored inside the room, with the temperature
within the range of -10 ~ 40℃, relative temperature not exceeding 90%, non-
corrosive gases and well-ventilated condition. In the process of
transportation, they should be free of moisture, and handled with care.
Accessories
should be equipped with a 24-port / 250ml rotation bottle and a 500ml ball-
milling port collection bottle.
In case of needing flasks of other specification, the customer should purchase
otherwise.

Installation:
- After unpacking, check according to the packing list, clean and dry pieces of glass and put them in place according to the position of pictures. On the left side should be the body of principal machine, with the water tank container on the right side.
- The Rotary evaporator inserts the condenser tube embossing grinding port into the polytetrafluoroethylene connecting tube on the left side of the head of the main engine the Embossed-grinding mouth on the side of condensation pipe into the PTFE connection tube on the left side of head of principal machine, and turn back and forth after inserting tightly to make it to fit well.
- The condensing tube and collecting bottle are connected with each other, and the joint is coated with vacuum grease to enhance the sealing performance.
- Unscrew the black lock nut on the right side of head of principal machine, encase from the flange of threaded glass joints (see the figure below), and then screw the black lock nut into the head of principal machine smoothly and tightly.
- Connect the rotation bottle to the other end of threaded glass joint (Embossed-grinding mouth), screw on the nut with square rings, and make square rings button the flask rim closely. In case of needing to back off the rotation bottle, screw off the nut with square rings to make the bottle exit the Embossed-grinding mouth.
- Encase collection bottle on the ball-milling mouth of condensation pipe, and clamp with the clip.
- Water outlets are connected with rubber tubes for discharge.
- Vacuum port is connected to the vacuum pump through the vacuum tube.
- After injecting water into the water tank, the heating plug behind the water tank will be connected to the power line.
Operation:
- Power: 220V 50HZ
- Press the power switch to make it switch on (-), and turn the speed control knob, when the principal machine will begin to rotate.
- Press (▲ / ▼) keys, the head of principal machine will ascend or descend automatically.
- After injecting water into the water tank, press the heating key (-) and set the temperature, which can automatically control the heating process. Heating without water is prohibited.
- The process of aligning the head angle is as follows: first, loosen the plum blossom knob on the right side of stand pillar, turn the head of principal machine, and then screw it tightly after reaching the appropriate angle.
- After completion of commissioning, power and heating switches will switched to the state of Off (0), followed by the unplugging of power plug.
