1.1
Importance of the operating manual
A fundamental requirement for the safe and trouble-free operation of the
unit is to be familiar with the fundamental safety instructions and all
possible hazards.
The operating manual includes important information concerning the safe
operation of the rotational vacuum concentrator (RVC).
This operating manual, and in particular the notes on safety and hazards,
must be observed by all persons operating the unit.
In addition, the local rules and regulations for the prevention of accidents
must be complied with.

1.2
Intended use
CHRIST rotational vacuum concentrators are solely intended for
evaporation under rotation and vacuum. Possible areas of application
include:
• Concentration of DNA/RNA, proteins, etc.
• Sample preparation for HPLC/thin-layer chromatography, gas
chromatography and mass spectroscopy
• Isolation/synthesis of natural substances
• High-throughput screening (HTS)
• General evaporation tasks in laboratories
Any other use beyond this area of application is regarded as improper use.
Martin Christ Gefriertrocknungsanlagen GmbH cannot be held liable for any
damage resulting from such improper use.
Evaporation of solvent-containing products
(non-aqueous media)
In terms of the corrosion resistance, the use of organic solvents in aqueous
solutions is acceptable.
By design, rotational vacuum concentrators are chemically resistant against
most compounds that are typically used. However, by necessity, rotational
vacuum concentrators comprise several different materials, some of which
may be attacked and degraded by certain chemicals.
The manufacturing methods and/or conditions of exposure of the materials,
as well as the way the chemicals are applied, can influence the results.
Some of these factors are listed below:
• Manufacturing: Stress generated while sawing, sanding, machining,
drilling, polishing and/or forming.
• Exposure: Length of exposure, stresses induced during the service life
due to various loads (changes in temperature, etc.).
• Application of chemicals: by contact, rubbing, wiping, spraying, etc.
