Rotational vacuum concentration is often used in forensic medicine as a replacement for the previous nitrogen blow-down method. In this area, extracts are dried in the course of examination for substances such as narcotics or cannabis products.
This method can also be used to remove superfluous derivatisation reagents during specimen preparation for gas chromatography analyses.
Rotational vacuum concentration allows drying to be performed faster, in a more defined manner and with less effort, and it is suitable for both organic and aqueous solutions. It is more time-efficient because the specimens can be processed in parallel.
Martin Christ Freeze Dryers offers a wide range of solutions. Our RVC 2-33 CDplus is ideal for this application.
