2 Safety
7 R-210/215 Operation Manual, Version B
2 Safety
This chapter points out the safety concept of the instrument and contains general rules of behavior
and warnings from hazards concerning the use of the product.
The safety of users and personnel can only be ensured if these safety instructions and the safetyrelated warnings in the individual chapters are strictly observed and followed. Therefore, the manual
must always be available to all persons performing the tasks described herein.
2.1 User qualifi cation
The instrument may only be used by laboratory personnel and other persons who on account of
training or professional experience have an overview of the dangers which can develop when
operating the instrument.
Personnel without this training or persons who are currently being trained require careful instruction.
The present Operation Manual serves as the basis for this.
2.2 Proper use
The instrument has been designed and built for laboratories. It serves for activities associated with
evaporation of solvents.
It is used for:
Distilling solvents
Vaporizing of solvents
Recrystallization
Synthesis and cleaning of chemicals
Soxhlet extractions
Drying powders by means of the drying fl ask
The instrument can only be operated properly together with a heating bath.
2.3 Improper use
Applications not mentioned above are improper. Also, applications, which do not comply with the
technical data, are considered improper. The operator bears the sole risk for any damages caused by
such improper use.
The following uses are expressly forbidden:
Use of the instrument in rooms which require ex-protected instruments.
Use as a calibrating instrument for other instruments.
Determination of samples, which can explode or infl ame (example: explosives, etc.) due to shock,
friction, heat or spark formation.
Use in overpressure situations.
Use of unappropriate water or oil baths, especially the use of heating sources with temperatures
above 180 °C (e.g. a Bunsen burner, etc.).
Processing of hard, brittle materials (e.g. stones, soil samples, etc.), which can lead to the destruction of the evaporating fl ask.
Use with a sample weight of more than 3 kg within the evaporating fl ask.

2.4 Warning notices used in this manual
WARNING
Generally, the triangular warning symbol indicates the possibility of personal injury or even loss of life
if the instructions are not followed.
WARNING
Hot surface.
WARNING
Electrical hazard.
WARNING
Biohazard.
ATTENTION
With the general “Read this” symbol, ATTENTIONs indicate the possibility of equipment damage,
malfunctions or incorrect process results, if instructions are not followed.
NOTE
Useful tips for the easy operation of the instrument.
2.5 Product safety
The Rotavapor is designed and built in accordance with current state-of-the-art technology. Nevertheless, risks to users, property, and the environment can arise when the instrument is used carelessly or
improperly.
The manufacturer has determined residual dangers emanating from the instrument
if the instrument is operated by insuffi ciently trained personnel.
if the instrument is not operated according to its proper use.
Appropriate warnings in this manual serve to make the user alert to these residual dangers.
2.5.1 Instrument-related hazards
Pay attention to the following safety notices:
WARNING
Potentially hot surfaces during operation, especially at the water or oil bath (up to 180 °C).
Always be aware of the risk of being burned.
When using an oil bath, make sure that no water gets into the bath otherwise there is a serious
risk of being splashed by hot oil.
WARNING
Potential implosion risk if used with damaged glassware.
Risk of electrostatic discharge when the rotary evaporator is fi lled with solvents, e.g. via the feeding
tube, or when drying powders are used.
Beware of damaged or cracked glass parts.
Beware of the fi re hazard.

9 R-210/215 Operation Manual, Version B
WARNING
Potential explosion risk if solvent vapors accumulate within the instrument housing.
Always use the instrument in a well ventilated area.
Beware of damaged or cracked glass parts.
Beware of the fi re hazard.
2.5.2 Other hazards
WARNING
Certain solvents in or in the vicinity of the Rotavapor can form peroxides and/or are highly infl ammable.
Always be aware of the explosion risk when working with hazardous substances or with
substances of unknown composition.
Always provide a good ventilation within or in the vicinity of the system.
2.5.3 Safety measures
Always wear personal protective equipment such as protective eye goggles, protective clothing and
gloves when working with the instrument.
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 fl ask into the heating bath.
Combi Clips for fi xing the evaporating fl ask and for safe removal of fi xed ground-glass joints.
Ball joint clip for safe fi xing of the receiving fl ask.
Rods and holders for fi xing 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 fl ask 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.

Optional
P+G is a unique protective layer for glass components. It offers improved mechanical damage
resistance and increases protection against broken glass. It also makes sure that the solvent in the
receiving fl ask is not spilling, if the fl ask is damaged.
The protective shield (optional accessory) protects operators from broken glass, solvent splashes
and hot heating medium in case of accidents or an implosion.
With the support rod the condenser can additionally be clamped.
