1. Safety Instructions
• Read the operating instructions in full before starting
up and follow the safety instructions.
• Keep the operating instructions in a place where they
can be accessed by everyone.
• Ensure that only trained staff work with the appliance.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
When working under a vacuum in particular!
• Wear your personal protective equipment in
accordance with the hazard category of the medium to
be processed. Otherwise there is a risk of:
- splashing liquids,
- body parts, hair, clothing and jewellery getting
caught,
- injury as a result of glass breakage.
• CAUTION! Inhalation of or contact with media such
as poisonous liquids, gases, spray mist, vapours, dusts
or biological and microbiological materials can be
hazardous to user.
• Set up the device in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• Ensure that there is sufficient space above the device
as 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 unbelance.
• Beware of hazards due to:
- flammable materials,
- combustible media with a low boiling temperature,
- glass breakage.
• CAUTION! Only process and heat up media that has 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 appliance 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 appliance is not suitable for manual operation.
• Safe operation is only guaranteed with the accessories
described in the ”Accessories” chapter.
• Refer to the operating instructions for the accessories,
e.g. vacuum pump.
• Only use the device under an all side-closed exhaust,
or a compa rable protective device.
• Adapt the quantity and the type of distilland to the size
of the distillation equipment. The cooler must work
properly. Monitor the coolant flow rate at the cooler
outlet.
• The glass equipment must always be ventilated when
working under normal pressure (e.g. open outlet at
cooler) in order to prevent a pressure build-up.
• Please note that dangerous concentrations of gases,
vapours or particulate matter can escape through the
outlet at the cooler. 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 evaporating flask must rotate during the heating
phase.
• The glassware is designed for operation under a
vacuum of up to 10 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
Page 8

relief.
• CAUTION! Avoid peroxide formation. Organic
peroxides can accumulate in distillation and exhaust
residues and explode while decomposing!
• Keep liquids that tend to form organic peroxides away
from light, in particular from UV rays and check them
prior to distillation and exhaust for the presence of
peroxides. Any existing peroxides must be eliminated.
Many organic compounds are prone to the formation
of peroxides e.g. dekalin, diethyl ether, dioxane,
tetrahydrofuran, as well as unsaturated hydrocarbons,
such as tetralin, diene, cumene and aldehydes, ketones
and solutions of these substances.
• DANGER OF BURNING! The heating bath,
tempering medium, evaporator piston and glass
assembly can become hot during operation and remain
so for a long time afterwards! Let the components cool
off before continuing work with the device.
• ATTENTION! Avoid delayed boiling! Never heat the
evaporating flask in the heating bath without switching
on the rotary drive!Sudden foaming or exhaust gases
indicate that flask content is beginning to decompose.
Switch off heating immediately. Use the lifting
mechanism to lift the evaporator piston out of the
heating bath. Evacuate the danger zone and warn those
in the surrounding area!
• When the device is switched off or the power supply
disconnected, the internal safety lift removes the
evaporator piston from the heating bath.
• CAUTION! Never operate the device when the
evaporator piston is rotating and the lift is raised.
Always lower the evaporator piston into the heating
bath first before starting the rotation drive. Otherwise
hot tempering medium may be sprayed out!
• Set the speed of the drive so no tempering medium is
sprayed out as a result of the evaporator piston rotating
in the heating bath. If necessary reduce the speed.
• Do not touch rotating parts during operation.
• Imbalance may result in uncontrolled resonance
behaviour of the device or assembly. Glass apparatus
may be damaged or destroyed. In the event of
unbalance or unusual noises, switch off the appliance
immediately or reduce the speed.
• The appliance does not start up again automatically
following a cut in the power supply.
• The device is only disconnected from the power
Page 9
5
supply network if the device power switch is off or the
plug is pulled out.
• The socket for the mains cord must be easily
accessible.
• The voltage stated on the type plate must correspond
to the mains voltage.
• Socket must be earthed (protective ground contact).
• Removable parts must be refitted to the appliance to
prevent the infiltration of foreign objects, liquids etc.
• Protect the appliance and accessories from bumps and
impacts.
• The appliance may only be opened by experts.
2. Proper Use
The instrument is designed for distilling in schools,
laboratories or factories. Together with the accessories
recommended by manufacturer, the device is suitable for:
- quick and gentle distillation of liquids
- evaporation of solutions and suspensions
- crystallisation, synthesis or cleaning of fine chemicals
- drying of powder and granulate material
- recycling of solvents
This device is not suitable for using in residential areas or
other constraints mentioned in Chapter 1.
