ABSTRACT:
Different embodiments of a respirometer are described which are used to determine the BOD of less dilute samples that can be permitted in the standard BOD test procedure. Different embodiments of the respirometer are formed of a chamber, walls of which are formed from a membrane permeable to oxygen to permit reoxygenation of the contained sample in the respirometer. In order to ensure reliability in the computed value of BOD, the chamber of the respirometer incorporates a framed structure.
