A rotary evaporator is a device commonly used in chemical laboratories for the efficient and gentle removal of the volatile solvents from samples by evaporation.They are found in almost every organic laboratory. The rotation flask rotates and shapes a thin film in negative pressure condition by heating; it evaporates; then the vapor is condensed, liquefied, and recollected for separation.A thin film evaporator has a water bath that can be heated in either a metal container or crystallization dish.
A jacketed vessel is a container that is designed for controlling temperature of its contents, by using a cooling or heating “jacket” around the vessel through which a cooling or heating fluid is circulated. The jacket has ability to permits the uniform exchange of heat between the fluid circulating in it and the walls of the vessel.jacketed glass reactors are designed for reaction and mixing of different types of materials under a specific adjustable temperature and vacuum condition.
Short-path distillation is a distillation technique where the distillate travels a short distance. It separates the mixtures based on differences in their volatility in a boiling liquid mixture under reduced pressure. As the sample mixture is heated, its vapors rise a short distance into a vertical condenser where they are cooled by water. The use of a vacuum ensures that the atmospheric pressure within your system is removed, making it easier to distill denser molecules in a shorter amount of time.
Molecular distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference separation principle, but by different substances molecular movement of the average free path difference to achieve separation.Taking advantage of molecular distillation working principle, our MD system is a high efficient apparatus for distillation of plant oil concentrates.
The freeze-drying machine is a technical method in which the aqueous article is previously frozen and then the water is sublimated in a vacuum state to obtain a dry product. The freeze-dried article is easy to store for a long period of time, and the water can be restored to the pre-freeze form Keep the original biochemical characteristics, suitable for laboratory samples of freeze-drying experiments and a small amount of production.
The vacuum filter is mainly used for liquid-solid filtration under vacuum condition. It has been widely used in laboratories nowadays.Though filtration can be done simply with gravity, more often vacuum filtration is employed because it is much faster. Several points are worth remembering. First, be sure to clamp your filter flask securely. These flasks are easily upended. Use the trap between your filter flask and the aspirator.
