This Dean-Stark receiver is designed for azeotropic distillations using solvents that are heavier than water.

• Innovative and compact

The solvent vapor travels through tube “A” to a condenser inserted in the top standard taper outer joint. Vapors are condensed and collected in the reservoir section. The layers separate and the heavier than water solvent overflows through tube “C” back into the distillation flask. The upper water layer is drained out intermittently using the 4 mm PTFE stopcock “D”. Capacity of the lower reservoir is 50 mL.
