Distillation Apparatus suppliers Introduction The vacuum distillation equipment has the characteristics of low distillation temperature,high vacuum degree of the system,short heating time of the material and high degree of separation. How is vacuum distillation equipment used? 1.When installing the vacuum distillation instrument,you must select a rubber stopper of the appropriate size,preferably a grinding vacuum distillation unit. 2.Distillate contains a large amount of low-boiling substances,which must be distilled under normal pressure to distill most of the anti-mesh,and then distilled under reduced pressure with a water pump to remove low-boiling substances. 3.Stop heating,recover low-boiling substances,and check the connection of each part of the instrument to make it close. 4.Turn on the oil pump,then slowly close the safety valve and observe if the pressure on the pressure gauge reaches the requirement.If the requirement is not met,the safety valve can be used for adjustment. 5.When the pressure reaches a constant level,start heating the distillation bottle.When rectifying the monomer,a small amount of zeolite should be added to the distillation flask (usually an oil bath is used,and the temperature is higher than the boiling point of the distillate by 20 to 30°C.The volatile high boilers can be 30 to 50°C higher in the later stage. 6.After the distillation is finished,remove the heat source first,wait a little colder,and then gradually open the safety piston.When the balance of the mercury column in the pressure gauge drops,stop pumping.After the pressure is balanced inside and outside the system,remove the instrument and clean it.
