IT is a flask with side tube which is at an angle to the Flask.Angle can vary according to the requirement.It comes with vide range of capacities.It is used for distillation. It’s quality and durability is quite high. It is made of heat resistant borosilicate glass.It is also called distillation flask. This flask is used to separate mixtures of two liquids with different boiling points through evaporation and condensation. The flask has three main components;the spherical base, a cylindrical neck and a cylindrical sidearm. The top of the flask neck is typically sealed shut with a cork or rubber stopper. As the heated gasses change into gaseous form, they rise through the cylindrical sidearm that is connected to the flask neck.
Contents used for distillation in this flask should be heated gradually.It’s distilling arm is also called stem. The distilling flask, is also known as a fractional distillation flask or fractioning flask.It has the rounding bottom and a long neck from which the side arm protrudes. The higher the boiling point of a substance, the lower the side arm is the on the neck.
