Used for filtering; the bottom of the frit is a porous glass surface, which allows material to be trapped. The ratings correspond to the pore sizes. There are other kind of funnels for filtration using filter papers. for pouring solids into a beaker or any container. Other kind of funnels can be used to pour liquid. for pouring liquid into a beaker. A funnel with a wide mouth is used for solids and is called powder funnel.

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.
