A laboratory absorption tower is a scaled-down version of an industrial absorption tower used for experimental purposes within a laboratory setting. It is a specialized piece of lab apparatus designed to investigate the principles of gas-liquid absorption or scrubbing processes under controlled conditions. Typically, a lab absorption tower consists of a glass or transparent column filled with a packing material or trays to facilitate the gas-liquid contact. It is equipped with inlet and outlet ports to introduce the gas stream and remove the treated gas after absorption. Additionally, there are ports or connections to introduce the liquid solvent and monitor its flow rate. The tower may also have temperature and pressure control mechanisms to simulate specific conditions relevant to the experiment. Laboratory absorption towers are essential tools for researchers, chemists, and engineers to study the behavior of gases and liquids during absorption processes, optimize process parameters, and assess the efficiency of different solvents or packing materials. These experiments contribute to the development and improvement of industrial-scale absorption systems and help in solving environmental challenges related to air and gas pollution.

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

The Bernoulli tube apparatus, also known as a Venturi tube apparatus, is a scientific device used to demonstrate the principles of fluid dynamics, particularly the Bernoulli's principle. It consists of a specially shaped tube with a constricted region, often referred to as a Venturi section. When fluid (liquid or gas) flows through the tube, the constricted section leads to changes in pressure and velocity according to Bernoulli's principle, which states that as the velocity of a fluid increases, its pressure decreases and vice versa. This apparatus is commonly used in educational settings to visually illustrate how the flow of a fluid can affect its pressure, helping to explain various phenomena like lift in aircraft wings, fluid flow through pipes, and more.
