Audited Supplier Rotary evaporators are currently for sale with the favorable price and sincere service.
A rotary evaporator (rotovap or rotatvap) refers to a kind of equipment for solvent evaporation under reduced pressure, which is composed of a vacuum system, a heated water or oil bath, a condenser and a motor that rotates the evaporation flask. As its name suggests, what is special is that the evaporation flask can rotate.
A complete rotary evaporator is generally composed of the following parts, which cooperate with each other and all play an essential role in the working process of a rotary evaporator.
The sample can be evaporated at the evaporation flask.
The rotary motor is used to drive the evaporation flask rotating at a continuous and constant speed in order to obtain a larger evaporation area and higher evaporation efficiency.
The vacuum system can be used to reduce the pressure within the rotary evaporation system so that the solvent will have a lower boiling point at a reduced pressure.
The heating bath is usually a hot water bath, which can be used to heat sample in the evaporation flask and regulate temperature.
There are double spiral serpentine condenser coils, vertical condensing glass assembly and other types of condensate pipes, which are used to condense the evaporated sample.
The evaporation pipe has two functions. One is to protect the sample during its rotation, and the other is to enable the vacuum system to suck out samples.
The receiving flask can recycle the sample after it's being condensed.
A rotary evaporator is mainly used for evaporation, concentration, crystallization, drying, separation, and solvent recovery, and especially used for the continuous distillation of large amounts of volatile solvents under reduced pressure. With so many application purposes, there is no doubt that a rotary evaporator can be applied in a great variety of areas. For example, it can be used in the small and pilot experiments and production in the biological, pharmaceutical, chemical fields and even food-making industry.
There are several factors contributing to higher evaporation efficiency. Firstly, the rotating flask can rotate at a constant speed, and materials can form a widespread film on the inner surface of the flask, which improves the evaporation efficiency greatly. Secondly, the high-efficiency glass condenser can improve the evaporation efficiency as well. Last but not least, continuous feeding and high vacuum degree are another factors.
The stainless steel and aluminum alloy are widely used in the mechanical structure, and all glass parts are made of heat-resistant high borosilicate glass, which ensure a better security. Besides, the water/oil bath can be equipped with transparent covers to prevent splashing, and anti-explosion frequency changer and dynamo are available as well. All of these designs contribute to better security.
It's much more convenient to use a rotary evaporator, because the electrodeless speed regulation, digital display K type sensor and intelligent temperature control and other designs adopted by it.
