2.2 Mode of operation

2.2.1 Principle of the rotational vacuum concentration
This method is used for the particularly quick and gentle evaporation,
drying, purification, and concentration of samples.
Rotational vacuum concentration is an alternative to rotary evaporators that
use high temperatures and operate nearly at normal pressure. Because of
the vacuum, the sample boils at low temperatures, and water as well as
organic solvents can be evaporated in a particularly gentle manner. Due to
the fact that the sample rotates like in a centrifuge, the Boiling retardation
is prevented so efficiently that low pressure can be used. As a result,
temperature-sensitive samples can be concentrated by evaporation without
being damaged.
The solvent can be collected in a cooling trap and disposed of immediately
if desired.

2.2.1.1 Advantages of the rotational vacuum concentration
•No foaming of the samples, minimum loss.
•Several samples can be dried simultaneously.
•Concentration of the sample on the bottom of the vessel. This is
particularly advantageous for small volumes or dilute solutions.
•Suitable for drying aqueous and solvent-containing samples.
•For volumes < 1 ml up to > 3 l.
•Reproducible drying processes thanks to controlled process
parameters, such as the rotor chamber temperature (energy input for
the evaporation) and vacuum (up to the automatic adjustment of the
optimum operating pressure –depending on the pump systems).
•Easy and safe solvent recovery.

3.6 Safety instructions

3.6.1 Electrical safety
CHRIST rotational vacuum concentrators are units of safety class I. The
RVCs are equipped with a three-wire power cord and a 230 VAC safety
plug with earthing contact. Please comply with the following points in order
to preserve this safety feature:
DANGER
•Ensure that the local mains voltage matches the nominal voltage that is
stated on the name plate.
•Do not place any dangerous material, e.g. glass vessels containing
liquid substances, within the safety area of 30 cm around the RVC.
Spilled liquids may get into the RVC and damage the electrical or
mechanical components.
•Work on the power supply system must only be performed by certified
electricians.
•Inspect the electrical equipment of the unit regularly. Defects such as
loose or burnt cables must be eliminated immediately.

3.6.2 Mechanical safety
In order to ensure the safe operation of the RVC, please comply with the
following points:
WARNING
•Do not use the RVC if it was installed incorrectly.
•Do not use the RVC without panels.
•Do not use the RVC with accessories that show signs of damage.
•Only use the RVC with accessories that have been approved by the
manufacturer. In case of doubt, contact the manufacturer (see chapter
7.2 - "Service contact").
•Do not hold your fingers between the lid and the housing when closing
the lid. Risk of crushing!
•Do not hit or move the RVC during its operation.
•Do not lean against or rest on the RVC during its operation.
•Check the RVC and accessories before every start-up for any visible
signs of damage.
•Do not evaporate any substances that could damage the material of
the rotors, rotor chamber or lid of the RVC in any way. Highly corrosive
substances (e.g. hydrogen chloride HCl) damage the material and
affect the mechanical strength of the rotors and accessories.
•Stop the RVC immediately in the event of a malfunction. Eliminate the
malfunction or contact the after-sales service of Martin Christ
Gefriertrocknungsanlagen GmbH (see chapter 7 - "Malfunctions and
error correction").
•Ensure that all repairs are performed only by authorised and
specialised personnel (see chapter 7.2 - "Service contact").
