5L Rotary Evaporator

The laboratory instrument rotary evaporator is mainly used for continuous distillation of a large volatile solvents under reduced pressure . Especially for the concentration and crystallation 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 distillatin 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 , crystalltion , separation and solvent recovery of the heat senstitive materials .  

1. 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.

8.The series of modular design, strong expansibility, easy installation, convenient maintenance.
