A stirring rod, also known as a glass rod, is a slender, cylindrical piece of solid glass used for mixing chemicals and liquids in laboratory settings. Its smooth, inert surface makes it ideal for stirring solutions without reacting with the substances. The rod is typically about 20–30 cm in length, providing enough reach to mix in beakers, flasks, or other containers. Due to its heat-resistant properties, it can also be used to stir hot liquids without breaking or melting.
Description
Uses
- Stirring solutions: Glass rods are primarily used to stir mixtures or solutions, ensuring even distribution of solutes.
- Decanting liquids: When pouring liquids from one container to another, the glass rod helps guide the liquid along its surface to prevent splashing.
- Spreading liquids: In microbiology labs, glass rods (specifically bent into a “hockey stick” shape) are used to spread cultures on agar plates.
- Inducing crystallization: A glass rod can be used to scratch the inside of a container, inducing crystallization in supersaturated solutions.
- Testing for acidity: Glass rods can be used to transfer small drops of liquid onto pH indicator papers for acidity testing.

Beaker Simax
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.
