Bunsen Burner
This is a piece of apparatus that is used as a safe source of heat in laboratories using a single gas flame. A Bunsen has an inlet that is usually connected to an external source of laboratory gas by rubber tubing. Its flame is used not only for heating, but for combustion and sterilizing objects too.
Microscope
This is an apparatus that is used to give finer details of small objects that would otherwise not be seen by the naked eye or a hand lens. It does so by magnifying objects up to thousands times their original size. There exist two main variants of a microscope namely; a light microscope and an electron microscope
Weighing Balances
These are used to weigh the mass of substances in a laboratory. There are different types of weigh balances such as beam balance, spring balance, top pan balances and electronic balances.
It is essential for any laboratory to have a wide range of safety equipment at its disposal. They are intended to keep laboratory users and their working environment safe from injuries, corrosive chemicals, poisonous fumes or accidental fires while carrying out experiments. The list of protective gear ranges from: Safety Goggles 1. Purpose: Safety ...
Microscope 1. Purpose: Microscopes are used to magnify and visualize objects or specimens that are too small to be seen with the naked eye. They are essential tools in fields such as biology, microbiology, and materials science. 2. Components: A typical microscope consists of an eyepiece, objective lenses with varying magnification powers, a stage ...
Nuclear Magnetic Resonance (NMR) Spectrometer: 1. Purpose: An NMR spectrometer is used for the analysis of organic compounds’ structure and properties. It measures the nuclear magnetic resonance of atomic nuclei. 2. Components: It consists of a powerful magnet, radiofrequency (RF) transmitter and receiver, and a sample holder. 3. Usage: Researchers...
