Product Description

The laboratory instrument rotary evaporator is mainly used for continuous distillation of a large volatile solvents under reduced pressure . Especially for the concentration and crystallization of the extract and the distillation of the receiving liquid in the chromatographic separation can separate and purify the reaction medium . The basic principle of a rotary evaporator is vacuum distillation, that is , under the reduced pressure , the distillation flask is continuously roated as the solvent is distilled . The glass bottle filled with reaction contents is rotated and uniformly heated at a constant temperature . Under the condition of switching on negative pressure , the boiling point of the material is lowered , the liquid forms a film and evaporates , then the solvent is recovered through the glass coil condenser and the collector . It is an ideal equipment for concentration , crystallization , separation and solvent recovery of the heat senstitive materials .

Product Advantages & Features

  • This machine adopts advanced frequency conversion technology and electronic speed regulation, which can ensure the stable operation of motor. So this machine has high evaporation rate, high recovery.
  • Bath can reduce the damage degree in the lifting process. During the evaporation of low boiling point, collecting bottle can be immersed in bath, which can reduce the secondary evaporation.
  • The collecting bottle connected by mouth ball milling, easy loading and unloading, and it has high sealing.
  • High temperature durable seal, dynamic seal system has corrosion resistance and long service life, good air tightness under high temperature.
  • Using Japanese technology - AC induction motor, stepless speed regulation, no brush, no spark, can work long time effectively.
  • Rotary evaporator chassis, bath, main rod, shaft are made of high quality stainless steel, beautiful appearance and corrosion resistance.
  • Intelligent temperature control, water and oil bath, more widely used. The temperature fluctuation is relatively small, only±0.2℃, evaporation is more stable, not easy to wash away the material.
  • The series of modular design, strong expansibility, easy installation, convenient maintenance.
