Rotavapor R-250
It is always mandatory to wear personal protective gear such
as protective eyewear and protective clothing.
The machine must never be rotated without the snap flange
coupling being closed.
No distillation may be started unless the evaporating flask is
immersed in the bath. There is always the risk that the neck
of the flask might break off due to the great weight involved.
There is a risk of becoming scalded while changing evapo-
rating flasks. Wearing gloves prevents this.
Check the glass components regularly for possible damage,
spreading impact marks, or cracks.
Never interrupt the grounding conductor (protective conduc-
tor). Otherwise there will be the risk of an electrical shock!
The operator bears responsibility for providing proper instruc-
tion of his operating staff. To aid him in doing this, translations
of this Instruction Manual are also available in several other
languages. As an integral component of the rotary evapo-
rator, this Instruction Manual must be readily available at all
times to the operating staff at the location where they are
using the unit.
The operator must inform the manufacturer immediately of
any and all events relevant to safety that occur in his use of
this equipment.
2.7 Modifications
No modifications are permissible without consulting with and
obtaining the written approval of the manufacturer.
No glass assemblies other than those recommended by the
manufacturer may be used, nor may any glass components
be put together arbitrarily.
Only those components of the rotary evaporator intended
for fulfillment of its function may be installed in or removed
from the unit. This may be done either by hand, or with the
use of the tool supplied along with the unit. The removal of
safety devices or covers using some commercially available
tool is — other than for authorized commissioning personnel
— strict ly forbidden. Contact with parts that are electrically
live may result in fatal injury!
