Descripción

The Pear Shape Flask can increase the surface area of ​​the liquid and accelerate solvent evaporation. And if a large amount of oil is prepared, the final oil will flow to the bottom of the pear bottle to facilitate the removal and reduce the loss.

 

 

The use of a rotary evaporator for chemical instruments Why use a pear-shaped flask The
distillation flask is a pear-shaped or round-bottomed flask with a standard ground port, connected to a vacuum pump via a highly refluxing serpentine condenser, and another opening of the reflux condenser. It is connected to a receiving flask with a grinding port for receiving the evaporated organic solvent. There is a three-way piston between the condenser and the pressure reducing pump. When the system is connected to the atmosphere, the distillation flask and the liquid-collecting flask can be taken. Under the transfer of solvent, when the system is connected with the decompression pump, the system should be under reduced pressure.

 

 

When using, depressurize first, then start the motor to rotate the distillation flask. At the end, stop the machine first, then pass the atmosphere to prevent The distillation flask is detached during rotation.
