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.

vapor P-12 - are indicated by intersecting the ﬁgure.
