Risk of injury from breakage of glass with vacuum operation
The glassware is designed to be used at a vacuum to 2 mbar. Failure to observe this
may cause breakage of glass.
Z
Z
Risk of injury through operation with negative pressure
A power failure may produce negative pressure in the glassware and result in injury
following breakage of glass.
Z
Risk of injury from breakage of glass if weight is exceeded
For the evaporating equipment (evaporating flask plus contents) the maximum permissible
weight is 3.0 kg. Loads exceeding this risk breakage of glass at the steam pipe.
Z
Risk of injury from breakage of glass with collision
Depending on the size of the flask, the setting angle of the rotation drive and the
position of the heating bath and lift, the evaporator flask may be in contact with the
bottom of the heating bath.
Z
Risk of injury through toxic / corrosive gases or suspended particles
The open outlet at the cooler may allow gases, vapours or suspended particles to
escape in hazardous concentrations.
Z
Risk of burns from glass vessels
The evaporator flask and glassware assembly can become hot during operation and
remain so for a long time.
Z
Z
Risk of burns from splashing with hot tempering media
Do not operate the device when the evaporator flask is rotating and the lift is raised.

Condense out uncondensed vapours or discharge without risk.
If there is a risk that the distillation residue will decompose in the presence of oxy-
gen, only ventilate with inert gases.
Ventilate glassware manually.
When working with large loads, always use low speeds. Unbalanced loads can result
in breakage of the steam pipe.
Set variable end stop to limit the lower lift position.
Make sure that any risk is ruled out, e.g. with downstream cold traps, gas wash
bottles or an efficient extraction system.
Do not touch hot glass vessels without personal protective equipment.
Allow components to cool off before continuing work with the device.
Adjust the speed of the drive to prevent tempering medium being ejected from the
heating bath by the rotating evaporator flask.
