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 safety-
related 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 .2

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 inappropriate water or oil baths, especially the use of heating sources with temperatures

above 95 °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.

• Work with a sample weight of more than 3 kg within the evaporating flask.
