- Technical Specifications
Laboratory concentrators used under vacuum include a combination of heat, vacuum and centrifugal force to evaporate the samples. This method is used for evaporation, drying, purification and especially fast concentration.
Distillation systems and rotary evaporators use high temperatures for evaporation.
And operate at approximately atmospheric pressure or vacuum up to 100 mbar. Ice drying systems operate at very low temperatures and high vacuums up to less than 0.01 mbar.
Although sublimation preserves samples, it is time consuming and not all solvents are suitable for drying ice.
The vacuum concentration occupies the position between the two methods mentioned above. With the right parameter settings, the resulting products can also be frozen and sublimated in a kind of final drying process.
The boiling point for liquid evaporation depends on the nature of the material and the external pressure. Reducing the pressure significantly reduces the boiling rate of the solvent solution and thus prevents the samples from overheating.
Main features of rotary vacuum concentrator
- Many samples are dried simultaneously.
- Samples are concentrated at the bottom or walls of the tube (unlike vortex glass), which is especially useful with small volumes or dilute solutions.
- Suitable for drying water samples and samples that have a large amount of solvent.
- Easy and reliable solvent recovery
