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 qualification
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 Safety

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 flask
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 inflame (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 flask.
• Use with a sample weight of more than 3 kg within the evaporating flask.

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 insufficiently 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 filled with solvents, e.g. via the feeding tube, or when drying powders are used.
• Beware of damaged or cracked glass parts.
• Beware of the fire hazard.
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 fire hazard.

2.5.2 Other hazards

WARNING
Certain solvents in or in the vicinity of the Rotavapor can form peroxides and/or are highly inflam­mable.
• 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 Safety

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 flask into the heating bath.
• Combi Clips for fixing the evaporating flask and for safe removal of fixed ground-glass joints.
• Ball joint clip for safe fixing of the receiving flask.
• Rods and holders for fixing 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 flask 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 flask is not spilling, if the flask 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.

2.6 General safety rules

Responsibility of the operator The head of laboratory is responsible for training his personnel.
The operator shall inform the manufacturer without delay of any safety-related incidents which might occur during operation of the instrument. Legal regulations, such as local, state and federal laws applying to the instrument must be strictly followed.
Duty of maintenance and care The operator is responsible for ensuring that the instrument is operated in proper condition only, and
that maintenance, service, and repair jobs are performed with care and on schedule, and by autho­rized personnel only.
2 Safety
Spare parts to be used Use only genuine consumables and genuine spare parts for maintenance to assure good system
performance and reliability. Any modifications to the spare parts used are only allowed with the prior written permission of the manufacturer.
