Uses

Rather than estimating water content, it is not much more commonly used to extract water and thereby drive a reaction equilibrium toward the desired outcome? — Preceding unsigned comment added by 141.168.17.209 (talk) 09:55, 8 November 2020 (UTC)[reply]

As originally designed, it was meant very specifically to measure water content in petroleum products. A Barrett trap, with a stopcock on the burette is used for more general purposes. The use of a trap with an integrated burette may be less effective than using more general labware to produce a similar azeotropic reflux separation. Industrially you may find an application requiring a system like this, that is a cold trap with a valved condensate drain.

These are all often still called a Dean Stark trap, due to scientific naming conventions. Lemtil (talk) 16:44, 2 June 2023 (UTC)[reply]
