1. Safety notes
•Please carefully read the Manual before operating the
product, and observe the specifications on safe
operation.
•Please properly keep the operating instructions for
easy reference in case of need.
•Please ensure only suitably trained personnel can
operate this instrument.
•Please comply with the safety rules, personal safety
and accident prevention norms, especially when
creating vacuum!
•According to the type of medium handled, please wear
suitable protective devices when operating the
instrument; otherwise, the following dangers may
occur:
- Splatter of liquids
- Fly-out of parts
- Contamination of human body, hair or clothes by
splattered substances
•Warning! Inhale of contact with toxic liquids, gases,
spatters, vapor, dust, biological or microbiological
medium might cause damage to the operator.
•Place the instrument on a stable, clean, antiskid, dry
and fireproof table surface.
•Make sure there is sufficient space above the
instrument and the glass assembly might exceed the
height of the instrument.
•Before use, please carefully examine the instrument
and accessories especially the glass assembly for any
damage. Please do not use any damaged parts.
•Ensure the glass assembly is free of stress! Each of the
following reasons might result in damage to the glass
assembly:
- Stress due to incorrect installation
- Effect of external mechanical force
- Sharp change to the ambient temperature
•Ensure the instrument will not move due to vibration
when turning on the instrument.
•Note the danger caused by the following
circumstances:
- Flammable substance
- Flammable low-boiling-point medium
- Breakage of glass component
•Warning! Never distill or heat any substance whose
ignition point is lower than the temperature set for the

Rotary Evaporator
3
safety of the heating bath.
•The heating bath’s safety temperature shall at least
25 °C lower than the ignition point of the medium
being handled.
•Please don’t operate or use this instrument in an
explosive environment or underwater or use this
instrument to handle any dangerous substance.
•This instrument is only suitable for the medium that
does not react with the energy generated in the
handling process in a way that might cause danger.
Meanwhile, the substance being handled may not
produce danger due to energy generated in any other
manner such as illumination reaction.
•The instrument must be monitored all the time when
operating the instrument.
•Please don’t operate this instrument under
overpressure.
•To ensure the effective condensation of the motor
system, please do not block the vent of the motor
system.
•Only use of the accessories in the list of “optional
accessories” can guarantee the operational safety.
•Please refer to the operating instructions for heating
kettle.
•Please refer to the operating instructions for optional
accessories.
•Please use this instrument in a closed fume hood or
other suitable protective device.
•Select the distilling device according to the amount to
be distilled and the distillation type. The condenser
must work normally. Please monitor the flow rate of
the coolant at the outlet of the cooler.
•To prevent pressure buildup, the glass assembly shall
be kept vented when operating under normal pressure,
such as keeping the condenser open.
•Please note that gases, vapor or other substances can
pose danger through overflow from the upper opening
of the condensation tube. To minimize or avoid such
danger, please take suitable measures, such as
connecting the cooling tube and scrubbing bottle or
other effective extraction devices downwards.
•The glass evaporating flask may not be heated on one
side. The rotating evaporating flask must rotate at the
heating phase.
•The glass assembly’ design pressure tolerance is
10mbar. The venting valve (see the part of “Testing”)

Rotary Evaporator

must be opened before heating and once again after
cooling. When performing vacuum distillation, the
steam must be condensed before release or released
safely.
If the residue after distillation is likely to be
decomposed when exposed to oxygen, please add only
gas for stress release into it.
•Warning! Please be careful be avoid the formation of
peroxides, as the decomposition of peroxides
accumulated in the distillation process might result in
explosion.
Please protect any liquid forming peroxides from ray
of light, especially ultraviolet irradiation. Please be
careful to examine formation of any peroxides before
distillation and to remove the peroxides if any. Many
organics are easy to form peroxides, such as
methoxypyridine, diethyl ether, dioxane,
tetrahydrofuran, unsaturated hydrocarbostyril, such as
tetrahydronaphthalene, diene, isopropylbenzene,
ketone and solutions of the aforesaid substances.
•Warning! The heating bath, heating medium,
evaporating flask and glass assembly might become
hot in the operation process and remain hot for a while
after stop of the operation! Before further operation,
please let each part cool down.
•Note: be careful to avoid boiling delay! When the
instrument is not started up and rotated, never heat the
evaporating flask! Sudden appearance of foams or
gases indicates that the medium inside the evaporating
flask begins decomposing. Please immediately shut
down the heating bath and lift the evaporating flask
above the heating bath, keep the surrounding danger
area well ventilated and inform surrounding personnel.
•Note! When the evaporating flask rotates, never
operate the instrument. Before the motor is started up,
please lower the evaporating flask down to the heating
bath, otherwise the boiling heating medium might
splatter.
•When operating the instrument, if necessary, please
reduce the motor speed to prevent the medium in the
heating bath from splattering.
•When operating the instrument, never touch any
rotating parts. Due to the instrument or fabrication
problems, the instrument might be unbalanced,
possibly damaging the glass assembly. When
imbalance or abnormal noise occurs, please

Rotary Evaporator
5
immediately turn off the instrument or reduce the
rotation speed.
•In case of powering on after power failure, the
instrument will not automatically be started up.
•The power supply to the instrument will be
disconnected only when the instrument is turned off or
the power plug is pulled off.
•The power socket must be easy to operate.
•The actual supply voltage must be consistent with the
voltage specified on the instrument’s nameplate.
•The power socket must be grounded.
•To prevent possible infiltration of outside liquid,
moving parts must be mounted in place.
•Ensure the instrument and its accessories are protected
from extrusion and collision.
•Only professional repairman may open the instrument.
2. Scope of application
