Samples are precious, and so is your time.
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 vapour state by sublimation. This is extremely gentle, but time consuming. Rotational vacuum concentration occupies a position between the two methods mentioned above. At temperatures near room temperature and pressures of a few millibar, the sample (solvent) boils without freezing. This makes the method very fast. Another advantage is that the sample is not subjected to thermal stress, which is especially important with thermally unstable biological and clinical samples.
