Charles law apparatus
Original price was: $5,000.00.$4,500.00Current price is: $4,500.00.
The Charles’ Law apparatus is designed for laboratory demonstrations of how the volume of a gas changes in response to temperature variations while maintaining constant pressure. It provides an effective visual and quantitative way to validate Charles’ Law, showing the direct relationship between volume and temperature, and is often used to estimate absolute zero in experiments.
Description
Uses of Charles law apparatus
1. Demonstrating Charles’ Law
- The apparatus is used to show the direct relationship between temperature and volume. By heating a gas (typically air) in a sealed tube or cylinder, students can observe the increase in volume as the gas expands with rising temperature. This directly confirms Charles’ Law.
2. Measuring Gas Expansion
- In experiments, the apparatus allows scientists to accurately measure how the volume of a gas changes when subjected to different temperatures. It typically includes a graduated tube to quantify the expansion or contraction of gas, helping calculate proportional changes.
3. Determining Absolute Zero
- One of the key educational uses of the Charles’ Law apparatus is in experiments aimed at determining absolute zero, the theoretical temperature at which a gas would have zero volume. By extrapolating a graph of volume versus temperature, absolute zero can be estimated.
4. Studying Thermal Expansion of Gases
- The apparatus is useful for understanding the concept of thermal expansion. By manipulating temperatures, the apparatus helps demonstrate how gases expand when heated and contract when cooled.
5. Validating Gas Laws
- The Charles’ Law apparatus is often used alongside other experiments related to the ideal gas laws, such as Boyle’s Law and Gay-Lussac’s Law, to give students a comprehensive understanding of gas behavior under varying conditions of pressure, temperature, and volume.
6. Educational Tool in Thermodynamics
- It is commonly used in physics and chemistry labs to teach the principles of thermodynamics. Students can manipulate variables and observe results firsthand, enhancing their understanding of gas laws and their practical applications.

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.
Amber Bottles Polystop
A laboratory glass amber bottle is a specialized container commonly used in laboratories to store and protect light-sensitive substances, chemicals, or solutions. These bottles are made from amber-colored glass, which provides protection against ultraviolet (UV) and visible light radiation. The amber glass helps to minimize the degradation and decomposition of light-sensitive contents by blocking a significant portion of the light spectrum.
The amber color of the glass is achieved by adding iron, sulfur, and other compounds during the glass manufacturing process. This coloration is what gives the bottles their distinctive amber or brown appearance.
Laboratory glass amber bottles typically come in various sizes, ranging from small volumes of a few milliliters to large capacities of several liters. They often have a screw-on or snap-on cap, providing a secure and airtight seal to prevent spills, evaporation, and contamination.
Due to their ability to protect light-sensitive substances, laboratory glass amber bottles are widely used in chemistry, biology, pharmaceuticals, and other scientific fields where sample integrity and stability are crucial.
Barlows wheel apparatus
The Barlow's wheel apparatus is an experimental device used to demonstrate the conversion of electrical energy into mechanical energy through electromagnetic principles. It consists of a horizontal wheel or disk with radial metal spokes attached to its center. The wheel is mounted on an axle, allowing it to rotate freely.
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.
bell in vacuum with air pump with plate
A "bell in vacuum" apparatus is a scientific setup used to demonstrate the effects of reduced air pressure (vacuum) on sound transmission. It typically consists of a bell or sound-producing object enclosed within a sealed chamber from which air has been removed, creating a low-pressure environment. This apparatus is designed to illustrate how sound travels differently in a vacuum compared to in normal atmospheric conditions, highlighting the role of air molecules in sound propagation.
