Burette Clamp

Bar and gauge apparatus is used to demonstrate thermal expansion and cooling contraction in classrooms and laboratories.

A glass beaker is a cylindrical, open-top container made of glass, typically with graduated volume markings on its side. It is commonly used in laboratories for holding, mixing, and heating liquids, as well as for performing various experiments and chemical reactions. Glass beakers come in various sizes and are designed to provide easy observation of the contents and to withstand temperature changes without significant deformation or chemical interaction with the substances being used.

The best definition of a bell jar apparatus is a scientific instrument used in laboratories to create a controlled environment for various experimental purposes, such as studying the behavior of gases, conducting vacuum experiments, or demonstrating principles of physics and chemistry. It consists of a glass or transparent plastic container shaped like a bell, which can be sealed to create a vacuum chamber. The apparatus allows researchers to manipulate and observe the interactions of substances or objects within the vacuum or controlled atmosphere, often enabling investigations that wouldn't be possible under standard atmospheric conditions.
