Dean and Stark Trap
  Apparatus: an essential component of physical experimentation.

The Dean and Stark trap is an ingenious device for collecting water. It is used to drive the equilibrium position of a reaction which has water as a product to the right. The trap is used in conjunction with a solvent, such as toluene, which azeotropes water but which is not miscible with water and which is less dense then water. A reverse D&S trap is available for use with solvents, like 1,2-dichloroethane, are more dense then water. A neat bonus with the D&S trap is that volume of collected water, 18 mL = 1.0 mol, can be used to measure the progress of a reaction.
