User Warning
WARNING
Failure to follow all warning and instructions could result in serious injury. Your safety is very
important to us, we urge you to take the following precautions when using this product.
We are not responsible for injury or damage caused by misuse.
•Instrument must be grounded and away from any electromagnetic interference
•Use instrument in a laboratory environment with proper ventilation
•Before using the instrument, the user must have some basic knowledge of the equipment/process
and obtain related laboratory skills
•Do not retrofit the instrument, this may lead to electric shock or cause equipment failure
•Do not use instrument for applications not listed in the purpose section
•This instrument is not explosion proof; do not operate in an explosive environment
•If using flammable sample or organic solvents take caution in spilling hazards
•During operation be cautious of hot bath and rotating flask
•Do not disassemble the instrument. Electrical components can cause personal injury
•The instrument should use a separate power outlet
•Do not unplug the unit during operation. Turn off heating and rotating then switch the unit off
before unplugging the instrument
•Proper personal protection equipment shall be used during operation
•Instrument cannot be repaired without authorization of the vendor/manufacturer
•Do not position the unit in such a way as to make disconnection from power supply difficult.
NOTE: (This may affect the service life of the unit)
•Please make sure the power connection is correct and well grounded.
•Ensure that the glassware is free of cracks, chips, or any other notable defects. Do not use if
defective.
•Check that all hosing (vacuum/chilling) does not have tears or kinks
•Avoid cracking condenser barb connections or injection valve when assembling hosing by
rotating and pushing hosing on connections.
•Avoid overtightening clamps on glass joints. This can affect the seal of the joint and create leak
points. Double check all screws on clamps are evenly tightened.
•Check rotating screw caps on motor are tightened and making a seal with the glass.
•During operation place rotary evaporator on even surface and lock feet.
•Use vacuum grease in all connections.

Purpose
Rotary Evaporators are used to distill solvents from compounds with precise evaporation. These are
especially useful when trying to separate organic compounds from ethanol, or any other low boiling
point solvents. Boiling points can be lowered by pulling a vacuum on the system. The evaporating flask
rotates with variable speeds, allowing you to spin the solution into a thin film around the flask. With a
combination of a reduced pressure and large heating surface area, these are great for quick distillation.
Internal glass coil condenser cools solvent vapors, allowing them to fall into the collection flask. This
leaves you with distilled solvent, ready to use again.
The heating element is controlled by a PID controller, accurate to the degree. Slowly raise temperatures
to achieve your solvent’s boiling point without disturbing the extract.
Structural Features
•Dual thermocouple positioned for accurate bath temperature control
•PTFE valve cores, corrosion-resistant without any pollution
•Check valve between collection flask and condenser to allow the emptying of recovered solvent
without having to break vacuum
•Vacuum gauge and manifold for direct feedback of any vacuum loss
•Electric lifting bath with dual heating coils for uniformity
•Rigid frame to easily support and transport unit around laboratory
•Triple coiled condenser for maximum surface area
•Compact footprint
Unpacking
Note: The glassware set is fragile; unpack with care.
1. Open the package.
2. Check the parts according to the packing list. If there are any missing, please contact us.
3. Carefully clean the glass to maintain cleanliness before assembly.
4. Prepare all the tools needed for installation.

Connecting the unit to the main supply
This unit is supplied with an un-terminated mains cord. Connection to the supply must be made in
accordance with local regulations.
THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN NOTE: Refer to the unit
rating plate to ensure that the supply is suitable for the product
cable wiring is colored as follows:
UK / EU / US
Brown –Live
Blue –Neutral
Green/Yellow - Earth
Should the mains lead require replacement, cable 2.5mm2/12 AWG of harmonized code
HO5VV-F should be selected. This is dependent upon the power rating of the unit, see technical
specifications.
Hard Wired Models
The unit is fitted with a suitable cable which should be directly connected to a suitable rated supply
terminal. (See wire colors above).
IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN

Operation Panel Instructions
Powering the unit: Plug in the power cord and press the on/off switch on the lower left side of body.
When the rotary evaporator is on:
1. After the controller is powered on, it performs a self-test where all the values are displayed. This
is a standard state.
2. Speed setting- Press the knob twice, when “REV SET” flashes, turn the knob to adjust the desired
speed value. To confirm value, press knob again.
3. Temperature setting- Press the knob thrice, when “TEMP SET” value flashes, turn the knob to
adjust the temperature speed value. To confirm value, press knob again.
4. When the speed, time and temperature setting are set, press the rotation key or the heating key
to begin the operation.
5. Self-Tuning- if the temperature output is not the desired one, start auto-tuning. To access this
function, press and hold the temperature key more than 3 seconds. The temperature display area
flashes, and the controller enters the self-tuning. The temperature values will change three times;
the new set of PID parameters will appear. To exit, press and hold the temperature key for 3
seconds.
Note: CALL IN TO PERFORM THE SELF-TUNING FUNCTION. FAILURE TO DO SO MAY DAMAGE THE
UNIT AND VOID WARRANTY.
Operation of timer function
Time function is turned off.
If you need to turn it on, press the knob about 5 seconds until LK appears, turn the knob to set LK= 168
and find the parameter “nt” , set nt value as 1, press the knob until the Time appears in the screen.
