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.
