When ventilating the rotary evaporator with air or inert gas, be sure
to prevent formation of reactive or explosive media. The maximum
permissible operating pressure of the chilled condenser is 0.1 bar
rel.
Ensure that the evaporation flask rotates throughout the entire
heating phase (even during submersion/lifting) in order to avoid
heating only one side of the evaporation flask or experiencing a
vaporisation delay.
Ensure that the evaporation flask is immersed or lifted only at a low
speed. Increase speed only to the extent that no heating medium is
ejected from the heating bath.
All replacement parts should be properly stored and disposed of in
accordance with the applicable environmental protection regula-
tions. Ensure adherence to the pertinent national and international
regulations. This especially applies to parts contaminated with toxic
substances.
The rotary evaporator complies with the safety stipulations of
Directive 2004/108/EC for electromagnetic compatibility, Directive
2006/42/EC for machines, Directive 2011/65/EU (RoHS2) and
Directive 1999/5/EC (R&TTE). The following harmonised standards
are fulfilled:
DIN EN 61010-1
DIN EN 61010-2-010
DIN EN 61326-1
The rotary evaporator complies with the following according to
IEC 664:
