The main components of a rotary evaporator are: A motor unit that rotates the evaporation flask or vial containing the user's sample. A vapor duct that is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample. A vacuum system, to substantially reduce the pressure within the evaporator system.
The most suitable evaporator will have the highest heat transfer coefficient per dollar of equipment cost. [2] In optimising the design of an evaporator, another important consideration is the steam economy (kg of solvent evaporated per kilogram of steam used).
Animation of a spinning scroll compressor. Léon Creux first patented a scroll compressor in 1905 in France and the US. [2] Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively.
An evaporator is a type of heat exchanger device that facilitates evaporation by utilizing conductive and convective heat transfer, which provides the necessary thermal energy for phase transition from liquid to vapour. Within evaporators, a circulating liquid is exposed to an atmospheric or reduced pressure environment causing it to boil at a ...
Centrifugal evaporator patent from 1875. A centrifugal evaporator is a device used in chemical and biochemical laboratories for the efficient and gentle evaporation of solvents from many samples at the same time, and samples contained in microtitre plates. If only one sample required evaporation then a rotary evaporator is most often
the key to the perfect rotovap technique is finding the perfect speed of rotation, using a properly sized flask (never fill >50%), proper bath temp, and maintaining the flask level in the bath (if the solvent gets too low in the bath, it will bump more easily).
The vanes provide a large surface area over which volatile compounds can evaporate into the steam, and the rotation ensures a thin layer of the product is constantly moved over the moving cone. It typically takes 20 seconds for the liquid to move through the column, and industrial columns might process 16–160 litres per minute (960–9,600 L ...
Radial and circumferential seal plates are also provided to avoid leakages of gases or air between the sectors or between the duct and the casing while in rotation. For on line cleaning of the deposits from the baskets steam jets are provided such that the blown out dust and ash are collected at the bottom ash hopper of the air preheater.
