Test tube

A test tube, also known as a culture or sample tube, is a standard piece of lab glassware consisting of a short, open-topped tube with a rounded U-shaped bottom. Designed by Michael Faraday, these tubes are used in laboratories for mixing or heating substances. They can be made from glass or plastic, with some being reusable and others intended for single-use. Laboratory Test tubes and <a href="https://www.medikabazaar.com/diagnostics/test-tube-stand">test tube stand</a> are essential tools in various lab applications, with glass and plastic being the most common materials.
