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
The 230V unit will be supplied with an EU mains lead. Should the plug not be suitable for
connecting to the mains power supply in your territory, replace the plug with a suitable
alternative.
THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN. NOTE: Refer to
the equipment rating plate to ensure that the plug and fusing are suitable for the voltage and
wattage stated.
cable wiring is colored as follows:
UK / EU mains cable wiring is colored as follows:
Brown –Live
Blue –Neutral
Green/Yellow - Earth
Should the mains lead require replacement, cable of 1.5 mm2/14 AWG of harmonized code
HO5VV-F should be selected. This is dependent upon the power rating of the unit, see technical
specifications.
IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN
