Rotary Evaporator
Calibration of a rotary evaporator is a mandatory task to ensure good performance and operational safety in the laboratory. There are several methods to calibrate a rotary evaporator and they should be chosen based on the application, complexity and economic requirements. Researchers have tested and compared several ways to calibrate a rotary evaporator to determine which offers the greatest efficiency in different situations.
In a recent study, methods of calibrating a rotary evaporator by measuring steam temperature, steam pressure and solution concentration were compared. Vapor temperature was monitored using an infrared thermograph system, which allowed an accurate and reliable measurement. The vapor pressure was obtained by means of a vacuum pump, and indicates the degree of pressure at which the vapor passes through the equipment and how this influences the evaporation efficiency. The concentration of the solution was determined by means of a glucose and serum analyzer with an infrared detector.

Our best-selling Rotary Evaporator
Large capacity and large opening of evaporating flask give larger evaporation surface. The evaporating flask keeps rotating when it is constantly heated by water bath, and solvent evaporates more efficiently under vacuum condition. It can be used for pilot-scale production in biology engineering, pharmaceutical industry, chemical industry and food processing. It usually works with water circulating vacuum pump, diaphragm vacuum pump, recirculating chiller, constant-temperature circulator, low temperature circulating pump, etc.
- Patented technology of double sealing of Teflon(PTFE) and FV rubber ensures the negative pressure level.
- Automatic switch valve makes continuous collection possible without affecting vacuum degree and without stopping distillation.
- Teflon discharge valve is corrosion resistant and contamination free.
- Water bath jacket protecting operator from scalding by hot liquid.

Rotaif Evaporator assembly
A rotary evaporator is laboratory equipment used to remove or recover solvents at low pressure. This instrument is used to evaporate substances through the distillation process, to later be condensed and finally separated into its components one by one, thanks to its specific boiling points.
The sample to be processed is inserted into the separation flask, which is submerged in the water, and subsequently the thermoregulated bath and the rotation system are turned on, then by the action of the vacuum pump, the pressure is reduced, allowing the solvents to separate from the solutes, and that these solvents will be distilled in the condensation tube at low temperature and collected in the flask intended for it.
