2.5.4 Safety elements

Electronics

• The heating bath is equipped with a mechanical and an electronic over-temperature protection.
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.

• Electronic control of the heating bath temperature - to prevent the product from overheating

Parts in direct contact with the instrument

• Safety catch for adjusting the immersion depth of the evaporating flask into the heating bath.

• Combi Clips for fixing the evaporating flask and for safe removal of fixed ground-glass joints.

• Ball joint clip for safe fixing of the receiving flask.

• Rods and holders for fixing the glass assemblies.

• Electronic over-current protection at the drive unit and lift motor.

• Safety spring preventing the vapor duct from dropping out.

• Automatic raising of the flask from the heating bath in case of a power failure.

Glass

• Use of high quality, inert 3.3 borosilicate glass.

• Use of tube clips GL-14 for preventing glass breakage.

9 R-210/215 Operation Manual, Version F

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
flask 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

4 Description of function

3

2

1

Fig. 4.1: Overview of a V assembly

a Evaporation area
The solvent is heated by means of a heating bath. A thin solvent film forms on the inside of the rotating

evaporating flask, resulting in an increased evaporation rate. The rotations also lead to an even mixing
of the sample thus preventing stationary overheating in the flask.

b Rotation drive including vapor duct
The drive unit ensures that the evaporating flask rotates evenly.

The integrated vapor duct transports the vapor from the evaporation area to the cooling area.

25 R-210/215 Operation Manual, Version F

c Cooling area
The solvent vapor flows 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.

d Receiving flask
The receiving flask collects the condensed solvent.

Vacuum
The vacuum reduces the boiling temperature and thus increases the distillation performance.

The evaporating performance is influenced by the distillation pressure (vacuum), the heating bath
temperature, and the rotation speed and size of the evaporating flask.
For information on the optimum distillation conditions, see chapter Operation.

Fig. 4.4: Quick-action jack

With the motorized quick-action jack, the eva­porating flask 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 a 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 flask is automati­cally raised from the heating bath.

4.3 Heating bath

The heating bath B-491 is multifunctional and can be used as a water bath or as an oil heating bath
up to 180 °C. The Heating Bath B-495 can be used as water bath up to 95 °C.
If you use a water bath, which is not suitable for the operation above 100 °C only water may be used
as heating medium (the use of any type of oils is not allowed). In case of an oil bath (e.g. B-491) only
specially approved heating bath liquids may be used. We advice against using silicone oils and low
molecular weight PEGs (Mol weight < 400 g/mol).

• Release the evaporating flask by turning the
clip counterclockwise.

NOTE

Secure the flask with one hand so that it does
not fall down.

• Fix the mounted evaporating flask by
pressing down the clamp and turning the
clip clockwise.

Handling the vapor duct:

• Remove the evaporating flask first, 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 fixing the evaporating flask.

4.5 Vapor temperature sensor

Fig. 4.7: Vapor temperature sensor

4 Description of function

The vapor temperature sensor measures the
temperature of the vapor entering the conden­ser. This temperature is displayed on the display
for vapor temperature and rotation speed (only
with R-215).

Fig. 4.8: Vapor temperature display at the R-215

4.6 Protective shield (optional)

Fig. 4.9: Protective shield

The protective shield protects the user from
splashes of heating medium when the flask is
rotating and from pieces of broken glass in the
unlikely event of an implosion of the evaporating
flask.

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 of 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 flask is carried out by the
vacuum controller, i.e. when suitably configured:

• the distillation is started via the vacuum controller, the evaporating flask 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
flask is raised from the bath.

Fig. 4.12: Infrared interface

The infrared interface transmits heating bath data to the controller. An interruption of the communica­tion with the interface does not affect the process.

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 Putting into operation

5.2 Electrical connections

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 F

5 Putting into operation

Saving energy
For heating baths there are various ways to save energy. By using floating 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 figure below.

Fig. 5.3: Heating Bath B-495 with water replenishment on the right-hand side

Fig. 5.4: Water flux within the heating bath replenishment of the Heating Bath B-495

5.3.2 Heating medium

If you use a water bath, which is not suitable for the operation above 100 °C only water may be used
as heating medium (the use of any type of oils is not allowed). In case of an oil bath (e.g. B-491) only
specially approved heating bath liquids may be used. We advice against using silicone oils and low
molecular weight PEGs (Mol weight < 400 g/mol). We recommend Ucon HTF 14, Sigma-Aldrich AG
as heating oil.

When the heating bath is used with heating oil
You should change the heating oil occasionally depending on the status of the oil (color, odor). If the oil
vaporizes (expecially low molecular weight PEG) make sure that it does not condense on the surface
of the Rotavapor as it can peel away the coating.

When the heating bath is used with water, please consider the following notes: Depending on the
water hardness a mixture of deionized water with distilled water to a ratio of 1:1 volume shares is
allowed. The use of the water bath with pure distilled or deionized water is not allowed due to the
corrosiveness towards stainless steel. In case the use of pure deionized or distilled water as heating
medium cannot be avoided, the addition of 1–2 g borax (Na2B4O7 x 10 H2O) per liter water is manda­tory.

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 flask 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.

little, than proceed as described above.

Fig. 6.4: Lowering and raising the evaporating flask

NOTE

When a 4 l evaporating flask is used the stop-position extension (Order no.: 44466) must be used
additionally.

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 flow through the condenser at approximately 40–50 l/h.

• Define the operating vacuum in such a way, that the boiling point of the solvent is 40 °C. The corre-

sponding pressure can be seen from the Solvent Table in chapter 3.

Advantages associated with bath temperatures of 60 °C:

• The evaporating flask 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 efficiency.

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 fulfilled:

• 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 flow 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 flask and make sure it does not exceed the
filling weight of 3 kg.

• Mount the evaporating flask.

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 first 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 flask into the bath.

46 R-210/215 Operation Manual, Version F

ATTENTION

Risk of overflowing.

• When you are operating with a 5 l heating bath, make sure that the controller is configured in a
way that the flask is not automatically submerged into the heating bath to avoid an overflowing of
the heating bath due to displacement. Introduce the flask 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 figure 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.

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 flask 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 flask 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 flammable vapor.

ATTENTION

When you carry out maintenance work at the lower part of the bath, always support it to prevent
instrument damage.

7 Maintenance and repairs

Use only genuine consumables and genuine spare parts for maintenance and repair to assure good
system performance and reliability. Any modifications to the spare parts used are only allowed with
the prior written permission of the manufacturer.

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 F

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

After 3 - 12 months, depending on the wear, the seals should be replaced.
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 calcified or contaminated.

• The oil in the oil bath has changed (color, viscosity, etc.).

• Light rust spots occur.

7 Maintenance and repairs

For this purpose, remove the heating bath from the Rotavapor and empty it.
In the case of minor calcifications, use a non-abrasive cleaning agent (e.g. a bathroom cleaner). If the
calcification is persistent, use e.g. acetic acid to remove it. Rinse the bath thoroughly afterwards. Rust
spots can easily be removed with Scotch-Brite. Make sure to add Borax when using deionized water
(see chapter 5.3).

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.
