Lab Vacuum Extraction Unit Lab vacuum extraction unit is heated by water bath (oil bath) to form thin film under the negative pressure condition, evaporate, then condense and recycle the solvent simultaneously. The apparatus are particularly suitable for the heat-sensitivity material’s condensation, crystallization, separation, recovery and so on. It is an important instrument for scientific research, pilot and production in biological pharmacy, chemical engineering and food industries etc. Lab Vacuum Extraction Unit Features: 1.AC induction motor stepless speed regulation, no brushes, no sparks, long life. 2.PTFE sealing system, high vacuum degree, high evaporation rates and recovery rates. 3.High quality borosilicate glass materials, good physical and chemical properties. 4.Easy visual operation with digital speed and temperature display. 5.PID temperature controller for accurate temperature control.
