Safety instructions
For your protection
• 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 ac-
cessed 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 micro-
biological 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 espe-
cially 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 re-
spectively 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 ha-
zardous 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 HB 10 basic/ digital hea-
ting bath.
• Refer to the operating instructions for the accessories, e.g. va-
cuum pump.
• Position the positive pressure outlet of the vacuum pump under
a fume hood.

• Use the HB 10.2 cover or the HB 10.1 spray guard.
• Only use the device under an all side-closed exhaust, or a com-
pa rable protective device.
• Adapt the quantity and the type of distilland to the size of the di-
stillation 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 dissi-
pated. If there is a risk that the distillation residue could disinte-
grate in the presence of oxygen, only inert gas must be admitted
for stress relief.
• CAUTION! Avoid peroxide formation. Organic peroxides can ac-
cumulate 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 ex-
haust 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, cu-
mene 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 ope-
ration and remain so for a long time afterwards! Let the compo-
nents 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!Sud-
den foaming or exhaust gases indicate that flask content is begin-
ning 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 disconnec-
ted, the internal safety lift removes the evaporator piston from the
heating bath. The maximum load (evaporator piston and contents)
is 1.5 kg for a permissible safety lift with no power.
• 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. Other-
wise 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 de-
stroyed. 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.
