Rotary Evaporators for laboratory - uses
Our rotary evaporators from our well-known laboratory equipment manufacturers Heidolph and IKA are primarily used by laboratories in the fields of chemistry, research, science and industry, as well as sometimes in different kitchens in the fields of gastronomy and food processing, where rotary evaporators are used in molecular kitchens for preparation and preparing meals. Nevertheless, as a basic piece of laboratory equipment, a rotary evaporator is primarily intended for distillation in the laboratory, specifically for the evaporation of solvents. Rotary evaporator distillation is essentially a common procedure in all chemical labs, and now fully automated rotary evaporators are also used. At a certain temperature and pressure, the liquids to be extracted evaporate, and isolate the solvents and the material they contain.
Lab Rotary Evaporators - structure
The rotary evaporator for use in the laboratory usually consists of a water or oil-filled heating bath or water bath, a steam tube at the end of which there is a evaporator flask, a vacuum-filled cooler and a storage flask. At the upper end, the rotary steam tube moves through the shaft seal into the recirculating cooler and is rotated by means of a continually rotating generator. The heat needed for distilling the solvents is supplied by means of a heating bath / water bath or an oil bath to achieve higher temperatures in which the evaporator flask is submerged. The external pump, normally a vacuum pump, is often attached to reduce the pressure. For vacuum distillation majority of laboratories use a modular system consisting of a rotary evaporator, vacuum pump and recirculating cooler.
Principle of Rotary Evaporators - function
The rotary evaporator for the laboratory is, in theory, a vacuum distillation system with an evaporator flask revolving around its longitudinal axis. Compared to conventional distillation, where the substance has an essentially standardized temperature, the rotary evaporator has two advantages: it improves the surface area and therefore the evaporation efficiency. The movement of the flask bubble forming and the evaporation of the solution are avoided because evaporation takes place primarily from the very thin film of the solvent on the wall of the flask. The practical theory of the rotary evaporator can be easily explained by its construction.
Thanks to the temperature of the evaporator flask in the hot bath, the solvent / substance to be distilled evaporates. The vapor passes through the steam tube into the refrigerator, where it condenses on the cooling surface and falls into the storage bottle. Effective isolation of liquids is accomplished because their boiling points vary and are not too close to each other, such as mixtures of methanol and ethanol. The boiling temperature can be lowered by means of a rotary evaporator with a vacuum pump, whereby solvents with a higher boiling point can be evaporated at lower temperatures than would be the case under normal pressure. In the case of lower boiling levels, a degradation of temperature-sensitive compounds to be extracted from the solution is prevented. The shaft lock seal protects the revolving steam tube from the atmospheric pressure and maintains constant ventilation in the center of the device.
Rotary Evaporator - accessories
The top-class rotary evaporators by renowned manufacturers are marked by their reliability, simplicity of use and long service life during many years of continuous use, as well as the versatility of being able to change parts or attach accessories. Depending on the evaporator model and the supplier, you can order specific parts and accessories for rotary evaporators such as numerous coolers, flasks, vacuum pumps, regulators, software, protective hoods, clamps, heating bath liquids and many other components for rotary evaporators that we sell.
