2 Safety
2.1 Intended use
The Rotavapor® R-100 is intended for evaporating and condensing solvents. It can
be used in laboratories and production facilities for the following operations:
Evaporating and condensing solvents and suspensions
Synthesis and purification of refined chemicals
Recycling and concentration of solvents
Recrystallization
Drying of powders and granulates
2.2 Use other than that intended
Use of any kind other than that described in the section Chapter2.1 "Intended use",
page7 and any application that does not comply with the technical specifications
(see Chapter3.4 "Technical data", page17) constitutes use other than that intended.
In particular, the following applications are not permissible:
Use of the device in an environment with a potential risk of explosion or areas
which require explosion-safe apparatus
Use of the device for processing substances in the food, animal feed or cosmetics
industries
Production and processing of substances that can lead to spontaneous reactions,
e.g. explosives, metal hydrides or solvents that can form peroxides
Working with explosive gas mixtures
Distillation of oil
Drying hard, brittle substances (e.g. stone or soil samples) that could damage the
evaporating flask
Shock-cooling of the evaporating flask or other glass components
Damage or hazards attributable to use of the product other than as intended are entirely at the risk of the user alone.

2.3 Staff qualification
Unqualified persons are unable to identify risks and are therefore exposed to greater
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 applica-
ble 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
safe and hazard-conscious working practices.
Safety-related incidents that occur while using the device should be reported to the
manufacturer (quality@buchi.com).
BUCHI service technicians
Service technicians authorized by BUCHI have attended special training courses and
are authorized by BÜCHILabortechnikAG 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.
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.
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.
u Wear work overalls or protective clothing.
u Do not wear loose or baggy items of clothing such as scarves or neck-ties.
u Tie up long hair.
u Do not wear jewelry such as necklaces or bracelets.
u At high speeds and/or high temperatures, use the optional safety guard or a simi-
lar protective arrangement.
2.4.6 Faults during operation
If a device is damaged, sharp edges or exposed electrical wires can cause injuries.
u Regularly check device for visible damage.
u If faults occur, switch off the device immediately, unplug the power cord and in-
form the operator.
u Do 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.
2 | Safety BÜCHI Labortechnik AG
10/60 Operation Manual Rotavapor® R-100
u Always wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
u Make 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.
u Use only genuine BUCHI accessories, spare parts and consumables.
u Technical modifications to the device or accessories should only be carried out
with the prior written approval of BÜCHILabortechnikAG and only by authorized
BUCHI technicians.
BUCHI accepts no liability whatsoever for damage arising as a result of unauthorized

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).
