• Tasks with the device must only be performed when operation is monitored.
• Operation with excess pressure is not permitted (for cooling water pressure, see "Product specifications").
• 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 (except lift movement).
• Safe operation is only guaranteed with the accessories described in the "User Replaceable Accessories
and Spare parts" chapter.
• Refer to the operating instructions for the HB 10 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 comparable 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 evaporating 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"Operation"). The equipment must only be aired again after
cooling. When carrying out vacuum distillation, uncondensed vapors 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 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.
• The heating bath, tempering medium, evaporation flask and glass assembly can
components cool off before continuing work with the device.
• Avoid delayed boiling! Never heat the evaporating flask in the heating bath without
become hot during operation and remain so for a long time afterwards! Let the
