Introduction:The rotary evaporator can be rotated under constant heating and negative pressure to form a thin film for efficient evaporation, followed by condensation and solvent recovery. It is particularly suitable for the concentration, crystallisation, separation and solvent recovery of heat-sensitive materials. Some models can also be used for reflux extraction. It is one of the essential instruments for the chemical industry, pharmaceutical industry, universities and research laboratories. It is also the main means of extraction and concentration in analytical experiments.We support customisation if other requirements arise.
