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.
Barometer tubes
A barometer tube is a slender, sealed, and typically transparent tube used in barometers to measure atmospheric pressure. It is usually filled with a liquid, often mercury, but sometimes water or another fluid, which rises or falls within the tube in response to changes in atmospheric pressure. The height of the liquid column in the tube serves as an indicator of the current atmospheric pressure, with higher pressure causing the liquid to fall and lower pressure causing it to rise. This measurement helps in predicting weather changes and understanding atmospheric conditions.
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.
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.
