Question

what is a beaker (scientific) ?

Answer 1

A wide, cylindrical glass container with a pouring lip, used especially in laboratories.Classically, a beaker is made from glass which has been specially treated to handle rapid temperature changes. Beakers can be placed in situations well below the freezing point, and they can also be rapidly heated without cracking. Some beakers are also designed to resist corrosive materials such as those found in a laboratory, and may have labels which indicate this, often on the bottom of the beaker. In some cases, the special treatment makes a beaker brittle, and it is a good idea to handle beakers with care.
