About This Product
The tubes hold small liquid or solid samples for precipitation, colour-change, solubility and reaction tests in chemistry and biology practicals. For heating, a tube is held in a test tube holder, warmed gently and evenly, and pointed away from people. Used tubes go back in a rack rather than lying loose on the bench, and are cleaned and inspected before reuse. Export supply of the Laboratory Sample Test Tubes can be arranged to laboratories and schools in Central African Republic, Benin, Bahrain, Burkina Faso and Côte d'Ivoire.
