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.

The best definition of a balance lever is a simple machine that consists of a rigid bar or beam that pivots around a fixed point called the fulcrum. It is used to compare the weights or forces of two objects and determine if they are in equilibrium (balanced) or if one side is heavier than the other (unbalanced). The balance lever operates on the principle of torque, where the torque (rotational force) exerted on one side of the fulcrum is equal to the torque on the other side when the system is in equilibrium. This principle is expressed by the formula: Torque = Force × Distance from fulcrum. By placing known masses or weights on one side of the lever and an unknown weight on the other side, the balance lever can be used as a weighing scale. When the lever is in balance, the two sides are equal in weight or force. This concept has been widely used in various applications, from traditional weighing scales to more complex systems like seesaws or construction equipment.

Bare enamelled copper wire is used as the main conductor of electricity. It has more unique features than bare copper

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.
