Abstract

The invention discloses a three-mouth flask which comprises a first bottleneck (1), a second bottleneck (2), a third bottleneck (3) and a bottle body (4), wherein, a connecting rod (5) is respectively arranged between the first bottleneck (1) and the second bottleneck (2) and between the second bottleneck (2) and the third bottleneck (3). The three-mouth flask provided in the invention is convenient to fix and heat.

Description

technical field [0001] The invention relates to laboratory instruments, in particular to a three-neck flask. Background technique [0002] The three-neck flask is a commonly used chemical glass instrument and is widely used in organic chemistry experiments. The three-neck flask is usually a round belly and a thin neck. It has three ports, which can add multiple reactants at the same time, or a condenser tube. Its narrow mouth is used to prevent the solution from splashing or reduce the evaporation of the solution, and it can be used with rubber stoppers to connect other glass equipment. When the solution needs to react for a long time or be heated to reflux, a three-necked flask is generally selected as the container. The three-necked flask is not suitable for stirring with a glass rod because the neck of the flask is very narrow. If it is heated to reflux, a magnetic stirrer can be placed in the bottle for stirring. Only when the bottle body and mouth are fixed can it b...
