Erlenmeyer flasks are used in chemistry labs for titration, especially of pH

Erlenmeyer flasks are often used to heat liquids, e.g. with a Bunsen burner. For that purpose, the flask is usually placed on a ring held to a ring stand by means of a ring clamp. A wire gauze mesh or pad is usually placed between the ring and the flask to prevent the flames from directly touching the glass. An alternative way to set up the apparatus is to hold the flask by the neck with a test tube clamp fixed to the stand.

If the flask is to be heated in an oil or water bath, a ' C' shaped lead or iron weight may be placed over the conical part of the flask to prevent it from floating in the bath
