Products Description

A round-bottomed flask is a type of flask-like glassware used in laboratories to hold liquid substances, especially for heating and boiling liquids. It has a rounded bottom, some of which are flattened at the bottom to make it easier to stand upright. It has a straight upward-facing neck that is used to move the contents in and out of the flask.

SHAPE AND DESIGN OF ROUND BOTTOM FLASKS AND DISTILLATION FLASKS:

Transparent glass boiling flask:

As the name suggests, the bottom is round and the neck is a normal straight tube. This design allows the round-bottomed flask to be heated uniformly and disperses the heat better, making it less likely to be damaged.

Distillation flasks:

They also have a spherical bottom, but have a thin glass tube extending slightly downward from the neck, which can be used to divert the vapour. In addition, the distillation flask already has a conduit in its structure to facilitate the preparation of the gas, using a stopper that can be punched with one less hole.
