Basic safety instructions
This user‘s manual and all safety instructions must be observed, read
and understood by all personnel working on the fixture (in particular in
reference to the safety instructions).
Responsibilities of the operating personnel
Verify that the distillation material can be evaporated safely and that the distillation
residue is not explosive.
Verify that work using an open flame is not conducted in the surroundings of the
rotary evaporator (explosion risk).
Verify that the flow rate of < 1 m/s is guaranteed when suctioning liquids that contain
combustible materials (electrostatic charge; ignition risk).
Verify that gases of explosion group IIC do not occur in materials or chemical
reactions, such as hydrogen.
Verify that equipment that is an emission or radiation source (electromagnetic waves)
for the frequency range (3*1011Hz to 3*1015Hz) is not operated or attached.
Verify that equipment that is an emission or radiation source for ionizing waves or
that is within the ultrasound range is not operated or attached.
Verify that adiabatic compression and shock waves do not occur (shock wave
ignition).
Verify that the use of substances with the risk of an uncontrolled release of energy
associated with a rise in pressure is prohibited (exothermic reaction; self-ignition of
dust).
Verify that the glass surfaces are wiped off by using only damp cloths.
Wear suitable protective clothing for activities on the rotary evaporator a (with gog-
gles and gloves, if necessary).
Avoid pressure on the LCD screen, it is not intended to be a touch screen interface.
Verify that the maximum excess pressure of the coolant equals no more than 1 bar in
the condenser.
Verify that the basic device is only plugged to or unplugged from the heating bath if
the main switch is switched off and/or the main power supply is disconnected.
Qualifications of Personnel
The target group of the rotary evaporator is qualified personnel only. The rotary evapora-
tor may only be used by personnel that have been trained in the proper operation by
qualified personnel determined in accordance with the internal safety regulations of the
facility in which the rotary evaporator is operated.
Safety Conscious Working
Heidolph Instruments is not liable for personal injuries and / or property damages caused
by an incorrect and improper usage of the rotary evaporator.
Observe the following regulations:
‒ Laboratory guidelines
‒ Accident prevention regulations
‒ Ordinance on Hazardous Substances
‒ Other generally accepted rules of safety engineering and occupational health
‒ Local regulations
