An electric bell is an electromechanical device that produces a ringing sound when activated by an electrical circuit. It consists of a solenoid (electromagnet) that, when energized, attracts a metal armature attached to a hammer. The hammer strikes a metal gong, creating the bell sound. The circuit continuously opens and closes as the armature moves, causing repeated strikes until the power is interrupted. Electric bells are widely used in doorbells, alarm systems, and various signaling applications in educational and industrial settings.

Absorption Tower
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.
Aspirator Bottle Glass
A laboratory aspirator glass bottle, also known as a vacuum aspirator bottle or a vacuum filtration flask, is a specialized glass container used in scientific laboratories for various applications. It is designed to create a vacuum or negative pressure, which allows the filtration of liquids through a porous medium like a filter paper or a membrane.
The bottle typically has a conical or pear-shaped body with a sidearm or neck near the top. This neck is where a rubber or silicone stopper is inserted, allowing for the attachment of tubing or a hose to connect to a vacuum source or water aspirator. (Available in 2.5l,5l,10l,)
Laboratory aspirator glass bottles are commonly used in vacuum filtration processes to separate a solid precipitate from a liquid solution. When connected to a vacuum source, the air inside the bottle is removed, creating a pressure difference that draws the liquid through the filter, leaving the solid behind on the filter paper.
These bottles come in various sizes to accommodate different filtration needs and are an essential tool in many research, analytical, and quality control laboratories for tasks like separating particulate matter, sterilizing solutions, and performing various filtration techniques. They are often made of durable borosilicate glass to withstand the pressure changes and chemical interactions that may occur during laboratory operations.
Atomic Model Set
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.
beaker pyrex
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.
Bernoulli Tube Apparatus
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.
