What is Vacuum Concentration / Evaporation?
Vacuum concentration is a gentle and fast method for concentration, drying, purification or evaporation of temperature sensitive samples (fluid products). During the process, liquid substances (including pure solvents) are evaporated through a vacuum process (typically ranging from 1 mbar to 30 mbar). To avoid overboiling, the samples are rotated during the vacuum concentration process.
Often as a lab, you need to make a choice between different concentration methods like vacuum concentration, distillation, rotary evaporation, vortex evaporators, nitrogen blowdown,…
With rotational vacuum concentration (RVC), you can prepare samples quickly without sacrificing gentle handling. This method can be used for evaporation, drying, purification and concentration.
Rotational vacuum concentration can be a true alternative for anyone who has previously worked with distillation systems, rotary evaporators or freeze dryers. Distillation systems and rotary evaporators use high temperatures for evaporation and operate at nearly atmospheric pressure. They are fast, but not especially gentle.
Freeze drying systems operate at very low temperatures and high vacuum. The samples go directly from the solid, icy state to the vapor state by sublimation. This is extremely gentle, but time consuming.
All this makes Christ rotational vacuum concentrators a good alternative. Rotational vacuum concentration occupies a position between the two methods mentioned above. At temperatures near room temperature and pressures of a few millibar, the samples (solvents) boil without freezing. This makes the method very fast.
Another advantage is that the samples are not subjected to thermal stress, which is especially important with thermally unstable biological and clinical samples.
During vacuum concentration, the material is centrifuged at a moderate speed of about 1,350 to 1,750 rpm. The resulting centrifugal force prevents samples splashing from bumping. The solvent is collected in separators or cold traps. This makes disposal easy, and in some cases enables reuse.
Rotational vacuum concentration is especially economical in practice. The method is suitable for drying a wide variety of aqueous and solvent-based samples. The volume range extends from one millilitre to three litres. The samples are concentrated at the bottom of the vessel, unlike vortex shakers. This is especially advantageous with small volumes and thin solutions. The method also scores well for effectiveness: a large number of samples can be dried simultaneously, saving time.
The drying processes are also easily reproducible. This enables controlled process parameters, such as rotor chamber temperature and vacuum level.
