2.4 Residual risks
The device has been developed and manufactured using the latest technological advances. Nevertheless, risks to persons, property or the environment can arise if the
device is used incorrectly.
Appropriate warnings in this manual serve to alert the user to these residual dangers.
2.4.1 Dangerous vapors
Distillation can produce dangerous vapors that are capable of causing life-threatening
toxic effects.
u Do not inhale any vapors produced during distillation.
u Ensure that vapors are removed immediately by a suitable fume hood.
u Only use the device in well ventilated areas.
u If vapors escape from joints or connections, check the seals concerned and re-
place them if necessary.
u Do not distill any unknown fluids.
u Observe the safety data sheets for all fluids used.
Page 9
BÜCHI Labortechnik AG Safety | 2
Operation Manual Rotavapor® R-100 9/60
2.4.2 High internal pressure
The evaporation of fluids can produce high pressures inside the flask or the condenser. If that pressure becomes too great, the glass components could explode.
u Make sure that the internal pressure inside the glass components is never greater
than atmospheric pressure.
u When distilling without a vacuum, set the vacuum pump to atmospheric pressure
so that excess pressure is automatically dissipated.
u If a vacuum pump is not used, leave the vacuum connection open.
2.4.3 Hot surfaces and liquids
The heating bath, evaporating flask and parts of the condenser can become very hot.
If touched they can cause skin burns.
u Do not touch hot surfaces or liquids or else wear suitable protective gloves.
2.4.4 Glass breakage
Broken glass can cause severe cuts.
Damaged glass components may implode if subjected to a vacuum.
Minor damage to the ground joints impairs the sealing effect and may therefore reduce diminish distillation capacity.
u Handle the flask and other glass components carefully and do not drop them.
u Always place the flasks in a suitable holder when they are not mounted on the Ro-
tavapor.
u Always visually inspect glass components for damage every time they are to be
used.
u Do not continue to use glass components that are damaged.
u Always wear protective gloves when disposing of broken glass.
2.4.5 Rotating parts
The evaporating flask and the vapor duct are rotated by the rotary drive unit. Hair,
clothing or jewelry can become caught up if allowed to come into contact with the rotating parts.
At high speeds, the heating fluid may be sprayed out by the rotation of the evaporating flask.

Operation Manual Rotavapor® R-100 11/60
3 Product description
3.1 Description of function
The Rotavapor® R-100 is a rotary evaporator with the aid of which single-stage distillation can be carried out quickly without unduly stressing the product. The basis of the
process is the evaporation and condensing of solvents using a rotating evaporating
flask under vacuum. Distillation under vacuum increases capacity and is more gentle
on the product.
The product is heated in the evaporating flask by the heating bath. The rotary drive
unit evenly rotates the evaporating flask. This constantly mixes the product, thereby
increasing the evaporation rate. Rotation also prevents localized overheating and delayed evaporation.
The vapor passes from the evaporating flask through the vapor duct into the cooling
section (condenser). There, the thermal energy of the vapor is transferred to the
coolant fluid so that the vapor re-condenses. The resulting solvent is collected in the
receiving flask and can then be reused or properly disposed of.
Distillation under vacuum
The distillation capacity depends on the temperature of the heating bath, the pressure
in the evaporating flask, the speed of rotation and the size of the evaporating flask.
Lower pressure, i.e. more vacuum, reduces the boiling point of the solvent so that it
requires less heating. That means that it can be distilled more gently and at a faster
evaporation rate than processes carried out under normal ambient conditions.
To prevent undesirable solvent emission and delayed evaporation, the vacuum has to
be adjusted to suit the application and kept stable. This can be achieved by means of
a vacuum pump (we recommend the BUCHI Vacuum Pump V-100) controlled by a
vacuum regulator (we recommend the BUCHI Interface I-100). We also recommend
that the temperature difference between the coolant fluid and the heating bath is
40°C (see Chapter6.2.2 "Adjusting distillation conditions", page34).

6.2 Performing distillation
DANGER
Risk of poisoning from inhalation of hazardous vapors
u Do not inhale any vapors produced during distillation.
u Ensure that vapors are removed immediately by a suitable fume hood.
u Only use the device in well ventilated areas.
u If vapors escape from joints or connections, check the seals concerned and re-
place them if necessary.
u Do not distill any unknown fluids.
u Observe the safety data sheets for all fluids used.
DANGER
Explosion risk from distillation of hazardous materials
u Do not distill solvents that produce explosive mixtures of gases.
u Make sure that there is always a sluggishly reactive atmosphere inside the sys-
tem.
u Discharge any electrostatic charge by suitable grounding arrangements.
u Keep sources of ignition away from the apparatus.
WARNING
Risk of explosion from excessive internal pressure
The evaporating flask and/or the condenser could explode if the internal pressure produced by evaporation becomes too great.
u Make sure that the internal pressure inside the glass components is never greater
than atmospheric pressure.
CAUTION
Risk of skin burns from hot components
u Do not touch hot components unless wearing suitable protective gloves.
To achieve optimum distillation results, the following procedure is recommended:
u Adjust the flow rate of the coolant to suit the type of coolant and the cooling capac-
ity. If tap water is used, the flow rate should be at least 40L/h.
u Make sure that the coolant temperature is not more than 20 °C.
u Pour solvent into evaporating flask and fit evaporating flask (see Chapter6.1.2
"Fitting the evaporating flask", page28).
u Make sure that the receiving flask is fitted.
u Close the glass stopcock.
u Switch on the rotary drive unit and adjust the rotation speed if necessary.
u Set the vacuum so that the boiling point of the solvent is 20°C below the tempera-
ture of the heating bath.
Page 33
BÜCHI Labortechnik AG Operation | 6
Operation Manual Rotavapor® R-100 33/60
u Immerse the evaporating flask in the heating bath (see Chapter6.2.1 "Raising and
lowering the evaporating flask", page33).
u Wait 1 – 2 minutes to make sure distillation starts.
u If necessary, adjust the vacuum and/or the heater temperature see Chapter6.2.3
"Optimization distillation", page35.
6.2.1 Raising and lowering the evaporating flask
CAUTION
Risk of scalding if heating bath overflows
u When immersing the evaporating flask, make sure that the fluid does not overflow
due to the displacement.
u When the evaporating flask is rotating look out for splashing fluid.
CAUTION
Risk of injury when adjusting apparatus height
u Make sure that your fingers are not trapped when adjusting the apparatus height,
especially when using the safety guard.
u Make sure that all tubing is long enough and is not under strain after making the
adjustment.
IMPORTANT
Risk of evaporating flask damage due to collision with edge of heating
bath
u Make sure that there is at least 10mm clearance between the evaporating flask
and the edge and/or bottom of the heating bath.
u Press and hold down the vertical adjustment handle release button (2).
u Move the rotary drive unit up or down by means of the vertical adjustment handle
(1).

34/60 Operation Manual Rotavapor® R-100
6.2.2 Adjusting distillation conditions
To obtain optimum distillation conditions, the energy absorbed by the solvent from the
heating bath must be removed again in the condenser. To achieve that, the following
settings are recommended:
Δ 20 °C
20 °C
40 °C
60 °C
Δ 20 °C
1
1
2
3
1 Coolant temperature: 20 °C
2 Vapor temperature: 40 °C
3 Heating bath temperature: 60 °C
The temperature difference between heating bath and evaporating flask and between
evaporating flask and condenser should be 20 °C in each case.
The pressure in the evaporating flask should be set so that the boiling point of the solvent is around 40°C (see Chapter10.1 "Solvent table", page47).
The flow rate of the coolant depends on the type of coolant used and the capacity of
the cooler but should be at least 40 – 50 L/h.
Those settings offer the following advantages:
The evaporating flask can be replaced without the risk of skin burns.
The evaporation rate of the water in the heating bath is low.
The energy of the heating bath is efficiently utilized.
To achieve optimum distillation, all devices in the system should be matched to one
another. Therefore, we recommend that the Rotavapor® R-100 is used together with
the BUCHI Vacuum Pump V-100 and the BUCHI Recirculating Chiller F-105 (see
Chapter3.2.4 "Typical application", page14). That will enable achievement of a stable vacuum and stable cooling, and thus a more efficient distillation process.
Page 35
BÜCHI Labortechnik AG Operation | 6
Operation Manual Rotavapor® R-100 35/60
6.2.3 Optimization distillation
Depending on the solvent involved, it may also be possible to further optimize the distillation process. The distillation should always be set up so that the condensate does
not cover more than three quarters of the coil in the condenser. There should be no
condensate visible in the top quarter.
¾
WARNING
Risk of explosion from excessive internal pressure
The evaporating flask and/or the condenser could explode if the internal pressure produced by evaporation becomes too great.
u Make sure that the pressure in the system is never greater than atmospheric pres-
sure.
If the condensation is below 3/4 of the condenser:
u increase the vacuum.
That will lower the boiling point and more vapor will enter the condenser.
u In applications where no vacuum is applied, raise the temperature of the heating
bath if necessary.
That will cause more solvent to evaporate.
If the condensation is above 3/4 of the condenser:
u decrease the vacuum.
That will raise the boiling point and less vapor will enter the condenser.
Page 36
6 | Operation BÜCHI Labortechnik AG
36/60 Operation Manual Rotavapor® R-100
u In applications where no vacuum is applied, lower the temperature of the heating
bath.
That will cause less solvent to evaporate.
6.2.4 Feeding solvent during distillation
Precondition:
R An external vacuum pump is connected and running.
R A feed tubing leading from the glass stopcock to the evaporating flask is fitted.
u Connect a supply tubing (2) for the solvent to the glass stopcock (1) and hold it in
