A test tube is a clear, cylindrical glass tube usually open at one end and rounded at the other, used in laboratory experimentation.
Test tubes are generally used for combining or collecting chemicals. They are used in a vast range of experiments though in big industry it is boiling tubes which are more commonly used.
Test tubes have been notably used, of course, in the production of the world's first IVF baby. In Vitro Fertilization literally means 'in glass' fertilization.
