What Are the Differences Between Beakers and Flasks?

Flasks are necked glassware used in laboratories to hold liquid substances. Because it can withstand a certain amount of heat, it is called a flask. Flasks are usually divided into flat and round bottoms and usually have the appearance of a round belly and a narrow neck. In chemical experiments, a container with a large amount of reagents and a liquid substance participating in the reaction.

The English name of the flask is "flask", so it can also be transliterated into a Flass bottle, which usually has a flat bottom and a round bottom. The flat bottom is called a flat bottom flask, and the round bottom is called a round bottom flask.

Flasks usually have the appearance of a round belly with a narrow neck, which is significantly different from a beaker. Its narrow mouth is used to prevent the solution from splashing or reduce the evaporation of the solution, and can be used with the rubber plug to connect other

It should be heated on an asbestos net to make it evenly heated; when heating, the outer wall of the flask should be free of water droplets.

The flat bottom flask cannot be used for heating for a long time.

If it is not heated, if a flat-bottomed flask is used as a reaction container, it is not necessary to fix it with an iron stand.

Main applications: (1) Reactor for liquid and solid or liquid.

(2) Equipped with gas reaction generator (normal temperature, heating).

(3) Distilled or fractionated liquid (using a branched flask, also known as a distillation flask).

Notes for use:

(1) The injected liquid does not exceed 2/3 of its volume, not less than 1/3 of its volume.

(2) Use asbestos mesh when heating to make it evenly heated.

(3) Distillation or fractionation should be used with rubber plugs, pipes, condensers, etc. Distillation flask

A glass container for liquid distillation or fractionation of substances. Often used in conjunction with condensate, liquid pipe, and liquid receiver. Can also be equipped with a gas generator.
