Description: Original title: Functions of various structures of rotary evaporator/rotary evaporator Function of each structure of rotary evaporator/rotary evaporator The rotary evaporator/rotary evaporator is an instrument for distilling a solvent. The purpose of distillation is to separate a given mixture into its components according to their respective volatilities by evaporation and condensation (liquid-gas-liquid) processes. Evaporation flask: The mixture to be evaporated is started in this flask,wiped film distillation,wiped film evaporator,jacketed glass reactor, rotary vacuum evaporator , which is rotated in a hot water bath. The size of the flask determines how much liquid can be distilled at one time. As long as the condenser can handle it, the bigger the better. The flask was first connected to a rotary evaporator/rotary evaporator and then the solvent was pumped directly into it. Do not take more than half the time to fill the flask or you will run into problems with boiling. But will also reduce that surface area and slow down the rate of distillation. The average flask has a special wide neck that makes it easy to remove and take out the product. Rotating driver: mainly controls the rotating speed of the flask. Water Bath: Fill to the extent that the mixture in the flask is submerged. The water bath transfers heat to the mixture quickly and efficiently. Water is a safe, inexpensive medium with uniform heat distribution and high specific heat capacity. Vapor line: This is where the vapor passes from the evaporation bottle to the condenser. This is also the most likely place to leak. Make sure the steam guide is super clean and centered. Rotary vacuum seals: take good care of the rubber ring! When not in operation,winterization filtration, remove the sealing strip from the rotary evaporator/rotary evaporator. Never lubricate them as grit can get into the grease and damage the steam lines. Condenser: Since the solvent surrounds the condensing coil with vapor, this portion of the instrument converts the vapor to a liquid (cooled using the same amount of energy required to heat the liquid to vapor). The vapor condenses into droplets, which are pulled down the coil by gravity into the receiving bottle. Return to Sohu to see more Responsible Editor:.
