2 Safety
2.1 Intended use
The Rotavapor® R-300 is intended for evaporating and condensing solvents. It can
be used in laboratories and production facilities for the following operations:
Evaporating solvents
Synthesis and purification of 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 Chapter2.1 "Intended use", page8
and any application that does not comply with the technical specifications (see
Chapter3.5 "Technical data", page20) 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
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
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
safe and hazard-conscious working practices.
Safety-related incidents that occur while using the device should be reported to the
manufacturer ([email protected]).
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.
