What should I pay attention to when purchasing a rotary evaporator?
Before buying a rotary evaporator, you need to consider four issues.First, what is the amount of distillation of the rotary evaporator? Second, what is the expected distillation solvent? What is the boiling point of the solvent? 4. What is the number of samples that need to be distilled?
Method and precautions during use of rotary evaporator
Rotary evaporators are primarily used to continuously distill large amounts of volatile solvents under reduced pressure. In particular, the concentration of the extract and the distillation of the receiving liquid in the chromatographic separation can separate and purify the reaction product.
How to choose a rotary evaporator when doing distillation purification experiments？
The rotary evaporator is an experimental equipment for rectification and purification in the laboratory. It is heated by constant temperature and rotated under reduced pressure (negative pressure) to form a film to continuously evaporate a large amount of volatile solvent, evaporate efficiently, and then condense and recover the solvent. The effect of purifying the separation, that is, under reduced pressure, the distillation flask is continuously rotated as the solvent is distilled.
