Alcohol burner. The glass alcohol burner (there are also metal ones), is one of the heating instruments used in laboratories. It consists of a container, a wick and a cap. Use methylated spirits (denatured methylated spirits). The following precautions must be followed when handling it: •Alcohol must not fill the lighter.

If it is covered directly, without taking this precaution, it can cause the hot air to expand inside the stopper, being able to produce a small explosion that makes the lid jump and gives quite a few scares to those who start these techniques without prior notice. .
Un tipo de tubo, semejante a la probeta pero sin base, en el cual por lo general se vierten líquidos, soluciones o muestras que analizar o con las que experimentar.
