NANBEI Is Professional On Providing One-step Solution Of Laboratory Instruments And Equipment
Rotary evaporators, commonly used laboratory instruments for evaporation and purification, are primarily used for the rapid evaporation of liquid samples under vacuum conditions to facilitate concentration, crystallization, or drying. They are widely applied in research and production in fields such as chemistry, biology, medicine, food, and materials.
Applications of small rotary evaporator:
1. Sample pretreatment
Commonly used for sample pretreatment processes, such as solvent removal and concentration. For example, in pharmaceutical analysis, it is used to extract and concentrate the active ingredients in medicine; in environmental monitoring, it is used to pretreat water and soil samples.
2. Solvent recovery
It can be used to recover organic solvents, reducing solvent waste and lowering experimental costs. For example, in chemical synthesis, it is used to recover solvents from reaction solutions; in experiments, it is used to concentrate solutions of biomolecules such as enzymes and proteins.
3. Crystallization process
It can be used in crystallization processes, allowing solutes in the solution to gradually precipitate and crystallize by controlling the evaporation rate. For example, in pharmaceutical synthesis, it is used to crystallize and purify compounds in the reaction solution.
Vacuum rotary evaporator mainly consists of motor, distillation flask,heating pot and condenser. During operation, it is essential to keep the water in the water bath, the water in the water pump, and the entire apparatus clean.
