The mechanical over-temperature protection consists of a bimetal thermostat that, in case of overtemperature (over 260 °C), directly interrupts the power supply. It has to be set back manually after
the bath has cooled down (see also chapter 8).
The electronic over-temperature protection controls the temperature limit (actual bath temperature
may not exceed the given temperature by 2 °C for more than 2 minutes), the heating rate (actual
temperature may not rise by more than 5 °C during 5 seconds) and the function of the temperature
sensor.
•
The heating bath is equipped with safety fuses.
•

4 Description of function
This chapter explains the basic principle of the instrument, shows how it is structured and gives a
functional description of the assemblies.
4.1 Functional principle of a Rotavapor
With a Rotavapor, single step distillations are performed quickly and in a product friendly manner. The
basis of this procedure is the evaporation and condensation of solvents using a rotating evaporating
fl ask under vacuum. Distilling products under vacuum increases the performance and helps to protect
the products.
4.1.1 Functional principle considering the V assembly as example
3
4 Description of function
2

Fig. 4.1: Overview of a V assembly
햲 Evaporation area
The solvent is heated by means of a heating bath. A thin solvent fi lm forms on the inside of the rotating
evaporating fl ask, resulting in an increased evaporation rate. The rotations also lead to an even mixing
of the sample thus preventing stationary overheating in the fl ask.
햳 Rotation drive including vapor duct
The drive unit ensures that the evaporating fl ask rotates evenly.
The integrated vapor duct transports the vapor from the evaporation area to the cooling area.
1
25 R-210/215 Operation Manual, Version B
Page 26
햴 Cooling area
The solvent vapor fl ows very quickly into the condenser. Here, the energy in the solvent vapor is trans-
ferred to the cooling medium (mostly water), so that the solvent condenses.
햵 Receiving fl ask
The receiving fl ask collects the condensed solvent.
Vacuum
The vacuum reduces the boiling temperature and thus increases the distillation performance.
The evaporating performance is infl uenced by the distillation pressure (vacuum), the heating bath
temperature, and the rotation speed and size of the evaporating fl ask.
For information on the optimum distillation conditions, see chapter Operation.

Fig. 4.4: Quick-action jack
With the motorized quick-action jack, the evaporating fl ask can be lowered into, and raised
from, the water bath. This operation requires no
physical effort. Motion is effected by an integral
1
motor. The button 햲 which can be pushed
up or down for the corresponding direction is
located on the handle of the quick-action jack.
When the instrument is switched off manually or
if a power failure occurs, the fl ask is automatically raised from the heating bath.

clip counterclockwise.
NOTE
Secure the fl ask with one hand so that it does
not fall down.
Fix the mounted evaporating fl ask by
•
pressing down the clamp and turning the
clip clockwise.
Handling the vapor duct:
•
Remove the evaporating fl ask fi rst, then turn
the clip clockwise until the vapor duct is
released.
NOTE
Press the lock button to block the drive unit
(position 5 in Fig. 4.2) while removing the
vapor duct or fi xing the evaporating fl ask.

4.7 Valve unit
Fig. 4.10: Valve unit
4.8 Woulff bottle
4 Description of function
If using the Rotavapor without the Vacuum Pumps V-700/710,
or with a vacuum controller other then the V-850/855, the valve
unit shuts off the connection ot the vacuum source when the set
point of the vacuum controller is reached. Also, the valve unit
serves as a separator to collect small amounts of liquid that may
have condensed in the vacuum tubing thereby protecting the
pump against contamination.
The Woulff bottle serves as safety vessel between the Rotavapor
and the vacuum pump. In case of an impure distillation the condensate is collected in the Woulff bottle and thus cannot reach
the pump.
Fig. 4.11: Woulff bottle
4.9 Combination of Rotavapor and vacuum controller
The vacuum controller controls the selected pressure within the Rotavapor and constantly corrects
any deviations. The Rotavapor and the vacuum controller can be connected, so that the starting and
stopping of the rotation and the raising and lowering of the evaporating fl ask is carried out by the
vacuum controller, i.e. when suitably confi gured:
the distillation is started via the vacuum controller, the evaporating fl ask is lowered until it reaches
•
the desired stop position (adjustable) and the rotation is started.
the distillation is stopped via the vacuum controller, the rotation is stopped and the evaporating
•
fl ask is raised from the bath.

Function of the infrared interface:
Transmits the current heating bath temperature to enable working with the solvent table.
•
Reads out the heating bath data (set / actual temperature) and transmits them to the Rotavapor.
•
From there, the data is transmitted via the RS-485-port to the vacuum controller (V-850/V-855).

5 Putting into operation
This chapter describes how the instrument is installed and gives instructions on initial startup.
NOTE
Inspect the instrument for damages during unpacking. If necessary, prepare a status report immediately to inform the postal company, railway company or transportation company.
Keep the original packaging for future transportation.
5.1 Installation site
Place the instrument on a stable, horizontal plane and consider the maximum product dimensions.
Perform the distillations under vacuum with the Rotavapor placed under a fume hood. If this is not
possible due to shortage of space, mount the protective shield (optional accessory) and lead the
exhaust gas from the pump into the fume hood.
5.2 Electrical connections
5 Putting into operation
ATTENTION
Make sure that the voltage on the socket corresponds to the voltage given on the type plate of the
instrument.
Always connect the instrument to an earthed socket. External connections and extension cables
must be provided with an earthed conductor lead (3-pole couplings, cable or plug equipment) as the
mains lead has a molded plug, thus avoiding risks due to inadvertent defective wiring.
Make sure that no electric sparks form in the instrument or its surroundings as they might damage
the instrument.
5.3 Commissioning the heating bath
Place the bath on the base plate of the Rotavapor.
If you need to adjust the position of the bath, lift
it up slightly at the right-hand side and pull or
push it to the desired position.
Fig. 5.1: Moving the heating bath
32 R-210/215 Operation Manual, Version B
Page 33
5 Putting into operation
Saving energy
For heating baths there are various ways to save energy. By using fl oating balls in the water bath,
evaporation of water is reduced. As a result, the bath heating has to switch on less often. This
measure helps to save up to 50% of energy. At the same time approximately 70% less water is used.
Additionally, a cover is available to put over the heating bath during operation which also saves energy
between distillations.
Fig. 5.2: Floating balls in the heating bath medium and cover for heating bath
NOTE
Turn on the heating bath about 10 –15 minutes before starting the distillation, since the bath has a
certain warm-up time. Turn off the heating bath after a distillation.
ATTENTION
As soon as the power plug is connected and the mains switch is turned on, the bath starts heating if
the actual temperature is below the set temperature. For this reason, make sure that there is always
heating medium in the bath to prevent instrument damage.
5.3.1 Heating Bath B-495
The Heating Bath B-495 is delivered with the bath replenishment mounted, see fi gure below.
Fig. 5.3: Heating Bath B-495 with water replenishment on the right-hand side

Fig. 5.14: Vapor temperature sensor
5.12 Functional test
5 Putting into operation
To measure the vapor temperature during
operation, the vapor temperature sensor must
be connected.
For this purpose:
Plug it into the socket at the rear of the R-
•
215 햲 (with an R-210 this is not possible).
Introduce the sensor into the corresponding
•
opening in the condenser and tighten it with
the GL-14 screw.
Carry out the functional test after all described steps for putting the instrument into operation are
fi nished.
Vacuum tightness test
NOTE
The vacuum tightness test can only be carried out with a vacuum controller installed or when you
have a pressure measuring device (manometer) connected to the tube between the pump and the
Rotavapor.
For this purpose, proceed as follows:
•
Start the instrument and adjust the rotation speed as desired.
Apply a vacuum. The instrument is now evacuated while the fl ask is rotating.
•
•
Now interrupt the vacuum to the Rotavapor by carefully bending the tube. You should see on
the vacuum controller or on the measuring device whether the vacuum in the system remains
constant, i.e. the pressure increase per minute should be less than 3 mbar.
If the vacuum does not remain constant, check all tube clips, retighten them and grease all ball
•
joints at the condenser side.
If that still does not help, replace the seals as described in chapter 7.3.2.
•
•
Afterwards, repeat the steps described above until the tightness test is passed.
Rotation speed test (for R-215 only)
To carry out the rotation speed test at the R-215, proceed as follows:
•
Slowly turn the adjusting knob for the rotation speed on the Rotavapor clockwise from the
minimum to the maximum setting. At rotations per minute > 20 the motor should turn smoothly at
each knob position. When the knob is not turned, the indication of the rotation speed should only
change by two digits up or down. In case the rotation speed does not remain constant or there are
problems with the motor, call the Buchi customer service.

6 Operation
This chapter explains the operating elements and possible operating modes. It gives instructions on
how to operate the Rotavapor properly and safely.
ATTENTION
Check the glassware for damages prior to each operation and use only glassware in perfect condition. Glassware with cracks, stars or other damages can break during operation.
6.1 Settings at the heating bath
6.1.1 Setting the heating bath temperature
ATTENTION
As soon as the power plug is connected and the mains switch is turned on, the bath starts heating if
the actual temperature is below the set temperature. For this reason, make sure that there is always
heating medium in the bath to prevent instrument damage.
6 Operation
WARNING
The heating bath can reach temperatures up to 180 °C. To avoid burns, consider the following:
•
Never remove a rotating fl ask from the bath because splashing oil can result in burns.
•
Make sure that no liquid can overfl ow from the bath when the evaporating fl ask is submerged.
•
Install the protective shield (optional accessory) only to a cold heating bath.
6.1.2 Switching the B-491 from water bath mode to oil bath mode
To switch the heating bath from water bath mode
to oil bath mode, proceed as follows:
Switch off the heating bath.

Switch on the heating bath.
•
As soon as the temperature is indicated on the
•
display, turn the knob to the 180 °C position
within 3 seconds. The indication “OIL” will now
appear on the display.
Fig. 6.1: Display in oil bath mode
ATTENTION
In the oil bath mode, always operate the bath with oil as the heating medium as water might start
boiling and evaporating which would lead to a heating bath damage.
After the oil bath has been standing opened for a prolonged period, condensation water can accumulate at the bottom. When the bath is used again, it must be heated above 100 °C with rotating
fl ask to drive the water out.
NOTE
A setting up to 180 °C is only possible in oil bath mode.

To re-adjust the stop-position later, push the
button 햲 up to raise the quick-action jack a
little, than proceed as described above.
Fig. 6.4: Lowering and raising the evaporating fl ask
6.4 Selecting the distillation conditions
To achieve optimal distillation conditions, the distillation energy supplied by the heating bath must be
removed by the condenser.
To ensure this, operate the instrument according to the following rule of thumb:
Cooling water: max. 20 °C Vapor: 40 °C Bath: 60 °C
How are these conditions achieved?:
Set the bath temperature to 60 °C.
•
Set the cooling water temperature not higher than 20 °C.
•
Allow cooling water to fl ow through the condenser at approximately 40 – 50 l/h.
•
•
Defi ne the operating vacuum in such a way, that the boiling point of the solvent is 40 °C. The corresponding pressure can be seen from the Solvent Table in chapter 3.
Advantages associated with bath temperatures of 60 °C:
The evaporating fl ask can be replaced without risk of burns.
•
The evaporation rate of the water from the heating bath is low (low energy loss).
•
The heating bath energy is used at a good degree of effi ciency.
•
This rule can also be applied to lower bath temperatures, e.g.:
Cooling water: 0 °C Vapor: 20 °C Bath: 40 °C

6.5 Distilling
To start operating the instrument, the following conditions have to be fulfi lled:
All electrical connections are established correctly.
•
All sealings are inserted correctly.
•
All joints are greased.
•
To start operating the instrument, proceed as follows:
Switch on the instrument.
•
Allow cooling water with a temperature not higher than 20 °C to fl ow through the condenser at
•
approx. 40–50 l/h.
Set the heating bath temperature to the desired value as described above and wait, until the
•
heating medium has reached its operating temperature.
Fill the solution you want to distill into the evaporating fl ask and make sure it does not exceed the
•
fi lling weight of 3 kg.
Mount the evaporating fl ask.
•
NOTE
Choose the pressure in such a way that the boiling point of the solvent is 40 °C (see solvent table).
Set the rotation speed.
•
NOTE
If the last distillation was an automatic one and you now want to carry out a manual distillation,
turn the knob for the rotation speed to its leftmost position fi rst before setting the rotation speed by
turning the knob to the right. Otherwise the instrument will not start operating.
•
Use the quick-action jack to submerge the fl ask into the bath.
46 R-210/215 Operation Manual, Version B
Page 47
ATTENTION
Risk of overfl owing.
•
When you are operating with a 5 l heating bath, make sure that the controller is confi gured in a
way that the fl ask is not automatically submerged into the heating bath to avoid an overfl owing of
the heating bath due to displacement. Introduce the fl ask manually instead.
•
After the set vacuum has been reached, wait for about 1–2 minutes to see whether distillation
begins.
•
If the distillation does not start, optimize the parameters (decrease the pressure gradually or
increase the bath temperature).
Both possibilities lead to an increased distillation capacity, see also chapter 6.6.
6.6 Optimizing the distillation conditions
Depending on the solvent being distilled the distillation might have to be re-optimized. In the optimized
case, the condenser should be steamed up to between 2/3 to 3/4, see fi gure below.
If this is not the case, there are two possibilities to optimize the distillation:
When the heating bath has reached 60 °C slowly reduce the pressure. Thus, the boiling point of
•
the solvent is reduced and Δ T
When the heating bath has reached 60 °C increase the bath temperature. Thus Δ T
•
resulting in an increase of distillation capacity as well.
increases resulting in an increase of distillation capacity.

6 Operation
increases

NOTE
When the bath temperature is increased, not all of the additional energy is used for distillation but a
major part is discharged into the environment due to the increasing difference between heating bath
and the ambient temperature.

6.7 When the distillation “dies out”
When the distillation “dies out”, replace the receiving fl ask to eliminate the risk of back evapo ration.
Then, continue distillation. Repeat this process until all desired solvent is distilled off.
At the end of the distillation, stop the rotation, pull the fl ask off and aerate the system.
If you do not intend to immediately perform another distillation, turn off the heating bath and cooling
water supply to save energy and resources.

7 Maintenance
This chapter gives instructions on all maintenance work to be performed in order to keep the instrument in good working condition.
WARNING
All maintenance and repair work requiring the opening or removal of instrument covers may only be
carried out by trained personnel and with the tools provided for this purpose.
WARNING
Electrical hazard:
Prior to all maintenance work on the instrument switch off the power supply and remove all
•
sources of fl ammable vapor.
ATTENTION
When you carry out maintenance work at the lower part of the bath, always support it to prevent
instrument damage.
Use only genuine consumables and genuine spare parts for maintenance and repair to assure good
system performance and reliability. Any modifi cations to the spare parts used are only allowed with
the prior written permission of the manufacturer.
7 Maintenance and repairs
7.1 Housing
Check the housing for defects (controls, plugs) and clean it regularly with a moist cloth.
ATTENTION
Never use solvents as cleaning agents as these might damage the instrument.
7.2 Tube connections and joints
Visually examine the tube connections regularly. When tubes become cracked and brittle, replace
them with new tubes.
Grease all joints on the condenser side regularly to achieve optimum tightness of the system.
7.3 Sealing system
ATTENTION
When removing and reinstalling the seals, make sure not to damage them. Always move them
perpendicularly to the axis of the glass parts and ensure no damage occurs to the sealing lip.
Never apply grease to the seals and never touch them with sharp object, otherwise they will get
damaged.
49 R-210/215 Operation Manual, Version B
Page 50
7.3.1 Cleaning the seals
To prolong the lifetime of the seals, rinse them regularly with water, especially if “bumping” occurred
during the distillation or if working with crystalline products. Afterwards, dry them with a solft cloth. To
remove the seals, see chapter 5.5, Installing the condenser and the seal.
7.3.2 Replacing the seals
Seals are subject to wear and tear, thus you should check them regularly and replace them, if necessary, e.g. if they do not pass the vacuum tightness test described in chapter 5.11 anymore. For this
purpose, see chapter 5.5, Installing the condenser and the seal.
7.4 Heating bath
The inner surface of the heating bath should be cleaned if:
•
The water bath is calcifi ed or contaminated.
•
The oil in the oil bath has changed (color, viscosity, etc.).
For this purpose, remove the heating bath from the Rotavapor and empty it.
In the case of minor calcifi cations, use a non-abrasive cleaning agent (e.g. a bathroom cleaner). If the
calcifi cation is persistent, use e.g. acetic acid to remove it. Rinse the bath thoroughly afterwards.
7 Maintenance and repairs
7.5 Glass components
To prolong the lifetime of the glass components, consider the following:
Rinse glass components with water and commercial cleaning agent (e.g. a mild soap solution).
•
NOTE
We recommend cleaning all the glass components manually.
•
Use an alkaline cleaner to remove dirt, e.g. algae, adhering within the condenser coil.
NOTE
When a thin copper wire is introduced into the condenser coil, the risk of dirt adhering to the
condenser coil is reduced.
•
Remove grease from joints. After you have cleaned and completely dried each glass component,
visually inspect the components for glass splinters or cracks. Since these components are under
vacuum when the Rotavapor is operating, they are subject to strain.
Regularly check the glass components for damages and only use glassware that is in perfect condition. Glassware with cracks, stars or other damages can break during operation.
