A Warburg Vessel for Soil Samples

Abstract

THE Warburg apparatus has often been used in soil research. Ellinger and Quastel1 stated that the physical state of a moist sample permits sufficient diffusion of oxygen for aerobic biological processes. Therefore in many experiments soil samples are used in naturally moist state without making a suspension. For such experiments the conventional form of Warburg vessel is not convenient. There are difficulties in filling and washing the vessels, in removing the samples for further analysis, etc. The side arm is useless, for it is not possible to pour off quantitatively the substrate, which must therefore be added directly to the sample at the beginning of the experiment.
