How does the rotavapor help the development of the pharmaceutical industry?

Rotavapors are widely used in large-scale sample concentration, drying, extraction, recovery, etc. It is an ideal equipment for scientific research experiments and industrial batch production in chemical, pharmaceutical, food, environmental protection, colleges and universities. It is understood that with the gradual implementation of energy conservation and environmental protection in the pharmaceutical industry, pharmaceutical companies have put forward higher and higher requirements for the energy-saving and environmental protection performance of various equipment. rotavapor is one of the important equipment for pharmaceutical production. Saving energy and protecting the environment are of great significance to drug production.

The basic principle of the rotavapor is vacuum distillation, that is, the distillation flask rotates continuously when the solvent is distilled under reduced pressure. The distillation flask is a pear-shaped or round-bottomed flask with a standard grinding mouth. It is connected to the vacuum pump through a high reflux serpentine condenser. The other opening of the reflux condenser is connected to a receiving bottle with a grinding mouth to receive the evaporated organic solvent. There is a three-way piston between the condenser and the vacuum pump. When the system is connected to the atmosphere, the distillation flask and the receiving bottle can be removed and the solvent can be transferred. When the system is connected to the vacuum pump, the system should be in a decompressed state. Then start the motor to rotate the distillation flask; after completion, the machine should be stopped first, and then the atmosphere should be turned on to prevent the distillation flask from falling off during the rotation. The rotavapor adopts stepless speed regulation to keep the glass rotating bottle rotating at a constant speed. The material forms a large area of ​​uniform film on the bottle wall, and then the rotating bottle is evenly heated using an intelligent constant temperature water bath. Evaporation is carried out at a high speed under vacuum conditions, and the solvent vapor is cooled by a glass condenser and recovered in a collection bottle. It is of great significance in the pharmaceutical production process. However, with the prevalence of green pharmaceutical manufacturing, energy saving and environmental protection will become the development trend of rotavapors.
