An Evaporation Chamber with Constant Suction1

  1. G. A. O'Connor and
  2. C. Cull2



Laboratory chambers to aid in the evaporation of water from soil surface have been described by numerous authors, but few units have been described which allow simultaneous collection of drainage water. This note describes the components and performance of an evaporation chamber enclosing a rotating turntable which allows the application of constant suction to multiple soil columns. The chamber will not be appropriate to all studies involving soil water evaporation, but offers certain advantages over conventially described units, particularly if suction needs to be applied to soil columns as they evaporate on a revolving turntable. Total cost of the chamber, including professional labor, was < $700.00.
