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.

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.
