Centrifugal concentrators induce solvent boiling under vacuum and hence samples are cold but, in contrast to freeze dryers, not frozen, and so the process can be faster than freeze drying. Care has to be taken with centrifugal evaporation of aqueous samples that are prone to freezing.
The vacuum in the evaporation system is created by a vacuum pump and by condensing the vapours from the last effect of the AlfaVap system in a condenser tailored for vacuum condensation. The most effective way to lower steam consumption in evaporation systems is to increase the number of effects. Each effect saves steam and cuts energy cost.
