3.2 Functional principle
햶
햴
햵
햳
햲
The rotary evaporator is used to carry out single-stage distillations at high speed and low stress. The process is based on
the evaporation and condensation of solvents using a rotating
evaporation flask. Distillation can be performed under vacuum
as well as under atmospheric pressure.
The following description is based on glass assembly V, for
example:
햲 Evaporation zone
The solvent in the evaporation flask is heated by the hot
bath. The rotating evaporation flask generates intensive
turbulence in the flask contents and forms a thin film of
solvent on the inside surface of the flask. This combination
of turbulence and film prevents local overheating and guarantees a high rate of evaporation.
햳 Rotary drive
The drive unit ensures uniform rotation of the evaporation
flask.
햴 Cooling zone
The solvent vapor flows at high speed into the condenser.
This is where the solvent vapor´s energy is transferred to
the cooling medium (e.g. water) – the solvent condenses.
햵 Collection flask
The collection flask is used to collect the condensate.
Figure 2: R-3000 glass apparatus V
6
햶 Vacuum connection
The solvent´s boiling temperature can be lowered by applying
vacuum. This results in a lower thermal load thus reducing
stress on the product.
The efficiency of the evaporator is influenced by the pressure
of distillation (vacuum), the temperature of the heating bath,
the speed of rotation and the size of the evaporation flask.
For details of how to select the optimum distillation conditions,
see Chapter 5.3, Selecting the conditions of distillation.

4.5 Sealing system
Assemble the complete sealing system in the order specified
(numbered), to prevent from destroying of the seal..
Seal KD-22 is subject to certain wear and needs to be replaced occasionally.
To prolong the life of this seal, observe the following points:
• Examine regularly.
• Clean only with soapy water or alcohol.
• Never apply grease.
• Never touch with any sharp objects.
4.6 Glass assemblies
All the ground-glass joints should be greased for optimum sealing
of the system.
Use only glassware that is in perfect condition and shows no
signs of damage. Examine the glassware each time before use.
The various types of glass assemblies are illustrated in Chapter
8, Replacement parts.
• The condenser can be fastened without having to remove
the union nut. Simply undo the nut just enough to push the
flange through.
• The collection flask must be secured with the ball joint clamp.
• The evaporating flask must be secured with the combi-clip.

General
• Hoses with an internal diameter of ~6 mm for connectors
with a GL14 union nut
Vacuum
• Keep the vacuum hoses as short as possible
• It is advisable to install a woulff bottle between the vacuum
source and the Rotavapor. The woulff bottle will prevent
solvent or solids from passing directly into the pump and
will prevent water from getting into the rotavap or when
using water-jet pumps

stop the rotation, therefore, before immersing or removing
the flask.
5.2 Performing a distillation run
In the following section we shall describe how to start, optimize
and end a distillation run on the basis of a checklist.
1. Rotavapor fully installed
All the electrical connections correct (power cable, heater).
All the seals properly installed.
All the ground-glass joints greased.
Evaporation flask attached.
12
2. Evacuate the Rotavapor to test for leaks.
Leak test as described in Chapter 6.2, Function test (< 3
mbar pressure rise/ min.).
3. Set heating bath to 60 °C
4. Water in bath has reached a temperature of 60 °C
5. Cooling water
Have cooling water flow through the condenser at a rate of
approx. 40–50 l/h and at a temperature not higher than
20°C
Page 13
BÜCHI Rotavapor R-3000 5 Operating the Rotavapor
6. Start the evacuation process
Select the pressure so the boiling point of the solvent is
40 °C (see solvent table in Chapter 5).
Feed in the solution through the inlet stop cock. Customers
with a C-assembly must introduce the sample into the
evaporating flask before evacuation.
Set the rotation.
Use the quick-lift to lower the flask into the bath.
1 to 2 minutes after the set vacuum level is reached
distillation should start.
If it does not start, you will have to make operating adjustments (lower the pressure or raise the bath temperature).
Ideally the condenser should be utilized between 2/ 3 and
3/4 of its capacity.
7. If the distillation slows down
Change the collection flask to rule out any risk of reverse
evaporation. Then continue the distillation as described in
point 6 (without drawing in more solution). Repeat this
process until all the solvents are distilled as required.
8. To finish
Stop the rotation, raise the flask out of the bath and aerate
the system (Aerate the system at a vacuum controller, or
at the stop cock.)
If you do not want to carry out the next distillation run
immediately, switch off the heating bath to save energy.

5.3 Selecting the conditions of distillation
Rule of thumb
For optimum conditions of distillation, the energy transferred
2
to the distillation from the bath must be removed again by the
condenser. To guarantee this relationship it is advisable to
apply the following rule of thumb:
Cooling water Vapor Bath
Difference D T1 Difference DT2
20 °C 40 °C 60 °C
20 °C 20 °C
How do you obtain these conditions?
• Have the cooling water (no warmer than 20 °C) flow through
the condenser at a rate of around 40– 50 l/ h
• Select the working vacuum so the boiling point of the solvent is 40 °C. Consult the following solvent table for the
corresponding pressure.
• Set the bath temperature to 60 °C.
Figure 12: Conditions of distillation
Advantages of a bath temperature of 60 °C
• You can handle the evaporation flask without risk of scalding
• Water does hot evaporate from the heating bath at such
a high rate
• The heating bath energy is utilized at a good level of
efficiency
Optimization of the distillation
Do not make any adjustments until the heating bath reaches
a temperature of 60 °C.
Depending on the solvent to be distilled, it may be necessary
to optimize the distillation by making certain adjustments. The
goal must be: Condensation of solvent between 2/3 to 3/4 of
the available condensing coils.
Basically there are two ways to optimize the distillation:
1. Slowly lower the pressure further (increase the vacuum)
This lowers the boiling point (and hence the vapor temperature) and raises the D T2 value. The result is a higher
efficiency of distillation.
or
2. Raise the bath temperature
This also raises the D T2 value (resulting in a higher efficiency
of distillation). At the same time, however, raising the bath
temperature increases the amount of heat loss from the
bath due to the bigger differential between the bath temperature and the ambient temperature.

6 Maintenance
6 Maintenance
Compulsory inspections and maintenance
All regulations aimed at keeping the Rotavapor in good working
order must be observed. They include cleaning the Rotavapor
at regular intervals and examining it for any signs of damage.
6.1 Cleaning and inspecting
Heating bath
Clean the bath with household detergent. If necessary, clean
the heater with anti-liming agent.
Glass components
Wash the glass components with commercial detergents (e.g.
a mild soap solution). Remove stubborn dirt (e.g. algae) from
inside the condenser coils with suitable cleaning agents
(if necessary, allow glassware to soak in the cleaning solution).
After cleaning and completely drying the glass components,
you must examine each item for signs of chipps or cracks.
The glass components of rotary evaporator are under vacuum
when in use – it is important, therefore, to carry out this visual
examination conscientiously!
Vapor duct
Follow the same procedure as for the other glass components.
Vacuum gasket KD-22
Examine the seal and replace with a new seal if signs of severe
wear are discovered.
• You will prolong the life of the seal by rinsing it and drying
with a soft cloth. This will also prevent condenser solvent
from entering into the drive unit.
• Clean the seal and glass components regularly, especially
after bumping and foaming defervescence and working
with crystalline products.
• Do not tilt the seal when fitting or removing it. Always move
it on the glass component at the axis of rotation. Do not
damage the sealing lip.
• Do not apply grease to the seal (fine abrasion and grease
act like grinding paste).
Housing
Clean the housing with a damp cloth but no detergents.
Examine also for defects (controls, plug).
Hose connections
Examine the hose connections and replace with suitable new
hoses if you discover any signs of cracking or brittleness.
17
Page 18
6 Maintenance
BÜCHI Rotavapor R-3000
6.2 Function test
Regular function checks will reduce the risk of your Rotavapor
breaking down and will prolong its useful life. We recommend
carrying out such a test once every three months.
Assemble the Rotavapor with dry and solvent-free glass components.
Vacuum tightness
Evacuate the Rotavapor to at least 200 mbar with the flask in
rotation.
Close the connection from the vacuum source to the system
(e.g. clamp the vacuum hose). If the unit is vacuum-tight, the
rise in pressure per minute will amount to less than 3 mbar. If
the values are higher than this, check the glass connections
and the KD-22 seal.
햳
햴
Adjustability of the speed of rotation
Turn the controller for the speed of rotation slowly from the
minimum to the maximum setting (in clockwise direction). The
motor should rotate without interruption in every position of
the controller.
Bath temperature control
The bath must be properly controlled at every temperature.
The heat up time should not exceed 15 minutes.
6.3 Replacing the quick-lift spring
If the spring in the quick-lift should ever break, you can replace
it without any difficulty.
Never open the quick-lift when the evaporator is in the down
position because the spring is under tensioned.
1. Move the quick-lift to the maximum up position.
2. Remove the cover plate from the quick-lift (one slotted
screw).
3. Extend the quick-lift by around another 4 cm.
4. Un-hook the spring 햳.
5. Move the quick-lift upwards until the guide 햲 is at the top
end of the rod (no further !). Now pull the pin 햴 out of the
spring holder.
6. Take out the spring and replace with a new one. Reinsert
the pin.
7. Move the quick-lift down slightly until you can hook the
spring in place again.
8. Lower the quick-lift.
9. Reattach the cover plate on the quick-lift.

7 Taking out of operation
All hoses and electrical connections must be disconnected
before transporting the Rotavapor.
The bath, the glass components and the quick-lift must each
be transported separately. If you want to transport the quicklift unpacked, make sure it is in its extended position otherwise
it could raise up unexpectedly.
The Rotavapor must be emptied of any harmful substances
and cleaned thoroughly (Chapter 6.3, Cleaning and inspecting).
This will rule out all risk of persons suffering injury from harmful
materials.
7.1 Storage/ Transportation
The Rotavapor should be stored in a dry place in its original
packaging. Also use the original packaging for any further
transportation.
7.2 Disposal
Every large component is marked with a material codey. It is
imperative to observe your regional and local laws and regulations concerning the disposal of waste materials.
