ASTM Distillation Appratus

Approx Price: Rs 8,500 / Piece 
Minimum Order Quantity: 1 Piece
      A batch of liquid is charged to a still fitted with some sort of heating devices. The charge is boiled slowly the vapors are withdrawn as rapidly as they form to a condenser where they are liquefied and condensate is collected in the receiver. The distillation column consist of several trays which allows the simultaneous travel of liquid down the tray and vapor up the tray, allowing mixing of the two face and there for equilibrium. The liquid mixture that is to be processed is known as the feed. The feed tray divides the column in to a top (enriching or rectification) section and bottom section. The vapor movies up the column and as it exits the top of the unit, it is cooled by a condenser. The condensed liquid is stored in a holding vessel known as reflex drum. Some of this liquid is recycled back to the top of the column and this is called vessel known as reflex drum that is removed from the system is known as the top product or distillate.

Parts of instruments : Distillation flask, cooling bath, heater, thermometer, receiving cylinder to collect distillate
