Thermopiles

A lab atomic model set is a collection of physical models and materials designed to represent the structure of atoms and molecules. It is commonly used in educational and scientific laboratory settings to visually demonstrate the arrangement of protons, neutrons, and electrons within an atom, as well as the bonding patterns between atoms in molecules. These sets typically include colored balls of various sizes representing different types of atoms, as well as connectors or magnets to simulate chemical bonds between them. The purpose of these sets is to help students and researchers better understand the principles of atomic and molecular structure in a tangible and interactive way.

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.
