parameters and conditions described in C apter 4, Tec nical data.
Protect t e rotary evaporator from moisture.
Ensure t at no azardous materials can enter t e surrounding
environment (including eating and cooling media), even in t e
event of glass breakage, leaks, or loss of cooling.
Ensure t at no azardous materials/reactions can be produced
t roug contact of processed solutions and solvents wit t e
eating and cooling media or t e ambient air. It may be necessary
to operate t e unit only under a suitable fume ood.
W enever t e rotary evaporator is operated outside of a suitable
fume ood (after eliminating t ese sources of danger), t e protec-
tive cover must be used (refer to C apter 11, Spare parts and
accessories, pg. 53).
Before using a substance, investigate its compatibility wit t e
materials used in t e seals and tubing.
Before using a substance, investigate w et er it can be evapo-
rated wit out danger.
Make sure t e tubes for gas and cooling medium are correctly
assigned on t e c illed condenser.
Adequately cool t e c illed condenser at all times.
Laboratory equipment and supplemental components attac ed to
t e rotary evaporator must meet t e specifications provided in
C apter 4.

Rotary Evaporator RC 900 Components and functions
Translation of original Operating Instructions, Englis , KNF 126291-126293 11/14 13
T e RC 900 rotary evaporator is designed for distillation and
evaporation of solvents. T e rotary evaporator is operated via t e
and terminal (Fig. 1/2, page 12).
T e solvent t at s all be evaporated is located in t e evaporation
flask (13). T e solvent is made to evaporate t roug t e proper
combination of temperature and vacuum. T e evaporation flask is
immersed into t e eating bat (15), in w ic a eating liquid is
located, typically water or a suitable oil. T e drive (9), continually
rotates t e evaporation flask inside t e eating bat . Once t e
solvent begins to evaporate, it rises t roug t e vapor tube and
into t e c illed condenser (7), w ic is continually cooled wit
cooling water or anot er cooling medium. Here t e vapor is cooled
to t e point w ere it condenses and collects (again in liquid form)
in t e collection flask (3).
T e c illed condenser and collection flask ave a transparent
coating t at protects t em against implosion.
A protective cover (accessory) is placed onto t e eating bat to
protect t e evaporation flask from implosion and to protect against
sprays.
5.2. Rotary evaporator functions
 Evaporation flask
T e evaporation flask's angle of inclination is adjusted via
t e rotary knobs (Fig. 1/12+20). Toget er wit t e ability to
move t e evaporation flask up and down and to displace
t e eating bat , t e rotary evaporator may be adapted to
various s apes and sizes of evaporation flasks.
T e drive (9) brings t e evaporation flask into rotation,
t ereby ac ieving a ig rate of evaporation:
- A more omogeneous distribution of temperature is
ac ieved bot in t e eating bat and in t e evaporation
flask (optimisation of temperature control and eat trans-
fer).
- T e moistened surface inside t e evaporation flask is en-
larged (increases eat transfer and t e boiling surface).
- Formation of a concentration gradient in t e solvent is
avoided.
Additional advantages of rotation include:
- T e danger of evaporation delay is reduced
- No localized over eating, no crust formation
T e and terminal (2) is used to switc t e rotation of t e
evaporation flask on or off and to select t e desired speed (see
C apter 8, Operating the rotary evaporator).
In addition, t e direction of rotation may be c anged at regular
intervals. T e interval at w ic t e direction of rotation c anges
is also adjusted using t e and terminal (see C apter 8, Oper-

Components and functions Rotary Evaporator RC 900
14 Translation of original Operating Instructions, Englis , KNF 126291-126293 11/14
ating the rotary evaporator). Regularly c anging t e direction
of rotation prevents deposition of salt in t e evaporation flask.
In t e event of a power failure t e evaporation flask is automat-
ically lifted from t e eating bat .
 Heating ath
T e rotary evaporator's eating bat (15) can be broug t
to and eld at a temperature according to t e requirements
of t e application in order to ac ieve optimal distillation.
T e eating bat may be pulled out on guide rails in order
to permit t e use of t e widest range of evaporation flask
sizes (see section Evaporation flasks).
T e specially s aped pouring lip makes it easier to empty
t e eating bat .

Function
T e and terminal is used to set t e process parameters used by
t e RC 900 rotary evaporator.
Settings are adjusted on t e and terminal's touc screen (Fig. 2/2)
or wit t e rotary knob (5).
T e wireless and terminal may be removed from its mount on t e
rotary evaporator (observe transportation safeguard Fig. 1/4, page
12) in order to control t e rotary evaporator remotely. T is makes it

Rotary Evaporator RC 900 Components and functions
Translation of original Operating Instructions, Englis , KNF 126291-126293 11/14 15
convenient to control t e evaporator w ile it is located under a
closed fume ood.
W enever t e and terminal is located in t e mount w ile t e
rotary evaporator is turned on, t e batteries in t e and terminal
will c arge automatically. T e batteries will c arge even if t e and
terminal is switc ed off. Alternatively, t e batteries can be c arged
t roug t e and terminal's included power supply (see mains
socket (4) on t e and terminal).
T e power supply also makes it possible to supply t e and termi-
nal wit electrical power directly from a mains.
A single tone on t e and terminal will indicate w en t e batteries
are nearly ex austed.
