One of the authors, G. TERUI, has already reported an improved manometer vessel with which one can measure oxygen consumption and carbon dioxide evolution by a single sample (TERUI, G., Kagakunoryoiki, Supplement 13,1954).The vessel has an auxiliary side arm embracing a CO_2-absorber tube containing KOH-paper. The absorber tube has a hole which leads to the main compartment and which one can open or shut optionally by revolving the tube (Fig. 1. B, in page 275).In this report, further improvement was contemplated and the vessels of inserted tube type were constructed. In this type, a CO_2-absorber tube is inserted into a cylinder sunk into the main compartment of the vessel as shown in Fig.1(C, D) and Fig. 2(page 275). The rates of CO_2-absorption of the improved vessels were compared with those of ordinary ones. It has been proved that when the hole of absorber tube opened toward the main compartment is large, e.g., larger than 8 mm in diameter in our case, the velocity constant of CO_2- absorption has sufficiently high value for the measurement of h and ho_2 alternately by a single sample (cf. Fig. 3,page 276). Examples of respirometry with improved vessels in comparison with ordinary ones are given.
