Ningbo Kaidi Science and Education Instrument Co., Ltd. will explain to you the purpose and precautions of using beakers
A beaker is one of the commonly used teaching instruments in chemistry laboratories. How should we use it in the laboratory and what should we pay attention to? Usage: The beaker is used as a reaction vessel for preparing solutions, dissolving substances, and larger amounts of substances at room temperature or under heating conditions.
Precautions for use: ① When heating the beaker, place asbestos mesh on it. Cannot directly heat the beaker with flames. Because the bottom of the beaker is large, heating it directly with a flame can only burn to a local area, causing uneven heating of the glass and causing it to explode When stirring dissolved substances, the glass rod should not touch the cup wall or bottom When heating liquid with a beaker, the amount of liquid should not exceed one-third of the beaker's volume to prevent liquid from overflowing during boiling. When heating, the outer wall of the beaker must be wiped dry.
