This flask has three necks in which two necks are Side necks.side necks are an angle to the main neck. It is manufactured from heat resistant boro-silicate glass. The ends of the necks are usually conical ground glass joints.It comes in various capacities.Stop-Cock size also varies with the size or capacity oth flask. Because of round bottom, cork rings are needed to keep the round bottom flasks upright.These flasks are commonly held at the neck by clamps on a stand. Uniform wall thickness distribution makes these flasks ideal for heating applications.
The geometry permits very uniform heating. It is mainly used in chemical or biochemical work. There is one tubular section known as the neck with an opening at the tip. This flask used in a laboratory for holding chemical liquids and solutions,also has a spherical shape for uniform heating, and one or more long cylindrical necks.It has a outer wall and it’s diameter varies according to the size or capacity.
