4 Description of function
This chapter explains the basic principle of the Multivapor P-6 and P-12 and provides a functional
description of the assemblies.
4 .1 Functional principle of the Multivapor
The Multivapor is a 6 or 12 position parallel evaporator for simultaneous evaporation of up to
6×150 mL or 12×30 mL sample volume, referred to as Multivapor P-6 or Multivapor P-12, respec-
tively. The basis of this procedure is solvent evaporation and condensation in vacuo using orbital
horizontal movement to produce a strong vortex in each sample tube. Distillation is usually performed
under vacuum to increase performance and reduce the boiling temperature preventing sample
decomposition.
The Multivapor is available as a stand-alone unit or in combination with a rotary evaporator, providing a
clever synergy enhancing solution by having two instruments, the Multivapor and the Rotavapor, share
the same condenser and vacuum assembly. The two configurations Multivapor P-6 and Multivapor
P-12 are not interchangeable as the orbital movement of the platform is different in order to guarantee
a smooth and safe operation.
