Used to hold round bottom flasks, to prevent them from rolling around and falling, and to keep them from touching the benchtop. This is used for starting a flame or often a bunsen burner. In general chemistry this is used to hold wire mesh to heat things on. This is used in all of the chemistries for measuring out small quantities of a substance relatively imprecisely.
