1 About this manual
7Multivapor™ 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 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 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 Safety
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 formation.
• 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).

2.5 Product safety
The Multivapor is designed and built in accordance with current state-of-the-art technology, however,
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:
!
Risk of minor or moderate burns when handling hot parts.
• Do not touch hot parts or surfaces (especially the heating plate with up to 95 °C)
!
Death or serious injuries by formation of explosive atmospheres (peroxides) inside the instrument.
• Directly withdraw released fumes and gaseous substances by sufficient ventilation at filling
• Before operation, check all gas connections for correct installation
• Establish inert system atmosphere before processing substances that can form explosive or
reactive gases or powders
• Check for proper earth connection to lead off electrostatic charges

2.5.2 Other hazards
Risk of glass breakage by excessive strains.
• Mount all glassware parts without strains
• Check glassware for proper fixing regularly and readjust fixing points if necessary
• Do not use defective glassware
• Use the protective shield (optional)
Risk of instrument damage by wrong mains supply.

2.5.4 Safety elements
Electronics
• The heating plate is equipped with an electronic over-temperature protection. It controls the
temperature limit (the actual heating plate temperature may not exceed the set temperature by
2 °C for more than 2 minutes) and the function of the temperature sensor.
• The heating plate is equipped with safety fuses.
Parts in direct contact with the instrument
• Combi clip for fixing the vacuum joint.
• Ball joint clip for safe fixing of the receiving flask.
• Rods and holder for attaching the condensation assemblies.
Glass
• Use of high quality, inert 3.3 borosilicate glass.
• Use of tube clips GL-14 for preventing glass breakage.
• PLASTIC+GLAS (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 spilled, if the flask is damage. All glass parts of the
condenser assembly are P+G coated.
2 Safety
Anti-seismic tie-down
• The instrument is equipped with a tie-down to fix it in the event of an earthquake.
• Optional
• The protective shield (optional but recommended accessory) protects operators in case of accidents from broken glass, solvent splashes, hot water, explosion or implosion.
2.6 General safety rules

In this section the items accessible by the ordering matrix are listed.
NOTE
The standard plastic material is PETP, however, for very harsh conditions such as trifluoric acid (TFA)
PEEK is available as a highly resistant alternative. In this case configure the system without evaporation unit and tube adapters (position „00“ in the matrix section „evaporation unit“) and order the
corresponding items separately as accessory.
