dangers.
The device may only be operated by suitably qualified laboratory staff.
These operating instructions are aimed at the following target groups:
Users
Users are persons that meet the following criteria:
They have been instructed in the use of the device.
They are familiar with the contents of these operating instructions and the
applicable safety regulations and apply them.
They are able on the basis of their training or professional experience to assess
the risks associated with the use of the device.
Operator
The operator (generally the laboratory manager) is responsible for the following
aspects:
The device must be correctly installed, commissioned, operated and serviced.
Only suitably qualified staff may be assigned the task of performing the operations
described in these operating instructions.
The staff must comply with the locally applicable requirements and regulations for

BUCHI service technicians
Service technicians authorized by BUCHI have attended special training courses and
are authorized by BÜCHI Labortechnik AG to carry out special servicing and repair
measures.
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.
uDo not inhale any vapors produced during distillation.
uEnsure that vapors are removed by a suitable fume hood.
uOnly use the device in well ventilated areas.
uIf vapors escape from joints or connections, check the seals concerned and
replace them if necessary.
uDo not distill any unknown fluids.
uObserve the safety data sheets for all fluids used.

2 | Safety BÜCHI Labortechnik AG
10/102 Operation Manual Rotavapor® R-300
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.
uMake sure that the internal pressure inside the glass components is never greater
than atmospheric pressure.
uWhen distilling without a vacuum, set the vacuum pump to atmospheric pressure
so that excess pressure is automatically dissipated.
uIf 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.
uDo not touch hot surfaces or liquids or else wear suitable protective gloves.
2.4.4 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.
uWear work overalls or protective clothing.
uDo not wear loose or baggy items of clothing such as scarves or neck-ties.
uTie up long hair.
uDo not wear jewelry such as necklaces or bracelets.
uAt high speeds and/or high temperatures, use the optional safety guard or a simi-
lar protective arrangement.
2.4.5 Faults during operation
If a device is damaged, sharp edges, moving parts or exposed electrical wires can
cause injuries.
uRegularly check device for visible damage.
uIf faults occur, switch off the device immediately, unplug the power cord and
inform the operator.
uDo not continue to use devices that are damaged.
2.5 Personal protective equipment
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
uAlways wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
uMake sure that the personal protective equipment meets the requirements of the
safety data sheets for all chemicals used.
2.6 Modifications
Unauthorized modifications may impair safety and lead to accidents.
uUse only genuine BUCHI accessories, spare parts and consumables.
uTechnical modifications to the device or accessories should only be carried out
with the prior written approval of BÜCHI Labortechnik AG and only by authorized
BUCHI technicians.

3 Product description
3.1 Description of function
The Rotavapor® R-300 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 in a rotating evaporating
flask under vacuum. Distillation under vacuum is more efficient and gentler on the
product.
The product is heated in the evaporating flask by the heating bath. The rotary drive
unit evenly rotates the evaporating flask. Rotation increases the surface area of the
liquid which leads to an increased evaporation rate. This also constantly mixes the
product which prevents localized overheating and delayed evaporation.
The vapor passes from the evaporating flask through the vapor duct into the cooling
section (cooling 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
Distillation capacity depends on the following factors:
Temperature of the heating bath
Pressure in the evaporating flask
Rotation speed of the evaporating flask
Size of the evaporating flask
Pressure in the evaporating flask: a low pressure (below atmospheric) reduces the
boiling point of the solvent. A lower boiling point means the solvent does not have to
be heated as much. Distillation under vacuum is more efficient and gentler on the
product.
Vacuum control: a stable vacuum adapted to the application prevents undesirable
solvent emissions and bumping (boiling) of the product. Control of the vacuum is
carried out by two means: the BUCHI VacuBox measures the current vacuum in the
distillation system. The BUCHI VacuBox is connected to the BUCHI Interface I-300 or
I-300 Pro. The BUCHI Interface is used to display the current readings and control the
components of the distillation system. See also Chapter5.16 "Assembling the BUCHI
distillation system", page44.
Heating bath temperature, coolant temperature and vapor temperature: to
ensure optimum distillation, it is important to make sure that the temperature
difference between the coolant and the heating bath is at least 40°C. The tempera-
ture of the rising vapor should be mid-way between the heating bath temperature and
the coolant temperature. See also Chapter6.2.3 "Adjusting distillation conditions",
page62.

BÜCHI Labortechnik AG Product description | 3
Operation Manual Rotavapor® R-300 13/102
3.2 Options
There are two different heating bath sizes for the Rotavapor® R-300:
The Heating Bath B-301 is suitable for evaporating flasks up to 1 L. See
Chapter3.5.3 "Heating Bath B-301", page20.
The Heating Bath B-305 is suitable for evaporating flasks up to 5 L. See
Chapter3.5.4 "Heating Bath B-305", page21.
As an additional option, the Rotavapor® R-300 can be operated with the Interface
I-300 or I-300 Pro. Connection of the interface unit to the Rotavapor® requires a
VacuBox.
The Rotavapor® R-300 is available with either manual or motorized vertical adjust-
ment of the rotary drive unit.
