A respirometer for determining oxygen demand of respiring liquid is described. The respirometer has a chamber to be filled with the liquid. The chamber includes a base plate, a cover plate, a plurality of supports extending between the base plate and the cover plate, and a side wall made of an oxygen permeable membrane. The cover plate has an opening therein which is capable of supporting a dissolved oxygen probe. The opening also acts as an inlet and outlet to the chamber. A rotor is provided in the chamber for stirring the liquid.
