A retort stand is used to hold and support test tubes. A common use of a retort stand is to hold a test tube while it is heated by a bunsen burner.
A retort stand helps to hold glass containers during various chemistry experiments. The stand is made of metal so that it can withstand intense heat from bunsen burners. It is made up of a number of components, including a clamp, base, rod and bosshead. Retort stands can be assembled using individual interchangeable parts; this allows individual components of the stand to be purchased and replaced rather than requiring complete replacement.
