8 Multivapor™ Operation Manual, Version E
2 Safety
This chapter highlights the safety concept of the Multivapor 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 or 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 supervision.
The present Operation Manual serves as a basis for training.
2 .2 Proper use
The instrument has been designed and built for laboratory use only. It serves for activities associated
with the parallel evaporation of multiple samples by means of heating under vacuum, with or without
regulation by a vacuum controller. The vacuum is typically applied by a PTFE diaphragm vacuum
pump.
Alternatively, the instrument can be used in combination with a rotary evaporator. In this case
the Multivapor serves as an accessory and is connected via an interface to the condenser of the
Rotavapor.
2 .3 Improper use
Applications beyond those described above are improper. Furthermore, applications which do not
comply with the technical data are also considered improper. The operator bears the sole risk for any
damages caused by such improper use.
The following applications are expressly forbidden:
• Use of the instrument in rooms which require ex-protected instruments.
• Use as a calibrating instrument for other instruments.
• Preparation of samples which can explode or inflame due to shock, friction, heat or spark forma-
tion.
• Use in high pressure situations.
• Processing of hard, brittle and abrasive materials (e.g. stones, sherds, soil samples, etc.) which
may destruct the sample tubes.
• Use of the instrument for digestions (e.g. Kjeldahl).
