the glass assembly may exceed the height of the device.
• Prior to each use, always check the device, accessories
and especially the glass parts for damage. Do not use
damaged components.
• Ensure that the glass assembly is tension-free! Danger of
cracking as a result of:
- Stress due to incorrect assembly,
- External mechanical hazards,
- Local temperature peaks.
• Ensure that the stand does not start to move due to
vibrations respectively unbalance.
• Beware of hazards due to:
- Flammable materials,
- Combustible media with a low boiling temperature.
Only process and heat media that
CAUTION
have a flash point higher than the
adjusted safe temperature limit of
the heating bath that has been set.
The safe temperature limit of the
heating bath must always be set to
at least 25 °C lower than the fire
point of the media used.
• Do not operate the device in explosive atmospheres, with
hazardous substances or under water.
• Only process media that will not react dangerously to
the extra energy produced through processing. This also
applies to any extra energy produced in other ways, e.g.
through light irradiation.
• Tasks with the device must only be performed when
operation is monitored.
• Operation with excess pressure is not permitted (for
cooling water pressure see "Technical Data").
• Do not cover the ventilation slots of the device in order to
ensure adequate cooling of the drive.
• There may be electrostatic discharges between the
medium and the drive which could pose a direct danger.
• The device is not suitable for manual operation (except lift
movement).
• Safe operation is only guaranteed with the accessories
described in the "Accessories" chapter.
• Refer to the operating instructions for the heating bath.
• Refer to the operating instructions for the accessories,
e.g. vacuum pump.
• Position the positive pressure outlet of the vacuum pump
under a fume hood.
• Only use the device under an all side-closed exhaust, or a
compa rable protective device.
• Adapt the quantity and the type of distill and to the size
of the distillation equipment. The condenser must work
properly. Monitor the cooling water flow rate at the
condenser outlet.
• The glass equipment must always be ventilated when
working under normal pressure (e.g. open outlet at
condenser) in order to prevent a pressure build-up.
• Please note that dangerous concentrations of gases,
vapors or particulate matter can escape through the
outlet at the condenser. Take appropriate action to avoid
this risk, for example, downstream cold traps, gas wash
bottles or an effective extraction system.
• Evacuated glass vessels must not be heated on one side;
the evaporation flask must rotate during the heating
phase.
• The glassware is designed for operation under a vacuum
of down to 2 mbar. The equipment must be evacuated
prior to heating (see chapter "Commissioning"). The
equipment must only be aired again after cooling. When
carrying out vacuum distillation, uncondensed vapours
must be condensed out or safely dissipated. If there is a
risk that the distillation residue could disintegrate in the
presence of oxygen, only inert gas must be admitted for
stress relief.
Avoid peroxide formation. Organic

Keep liquids that tend to form

in particular from UV rays and
check them prior to distillation

peroxides. Any existing peroxides
must be eliminated. Many organic

• The device does not automatically restart following any
interruption to the power supply, which can avoid over
boiling that could happen after power failure. Pease make
sure that the heating bath will not restart after power
failure.
For protection of the equipment
• The voltage stated on the rating plate must correspond to
the mains voltage.
• Socket must be earthed (protective ground contact).
• Removable parts must be refitted to the device to prevent
the infiltration of foreign objects, liquids, etc.
• Protect the device and accessories from bumps and
impacts.
• The device may only be opened by experts.
