Used for metabolic studies of biological materials. Particularly useful in measuring CO yields following incubation. Also suitable for in vitro incubations, insulin bio-assays, persulfate oxidations, and the "distillation" of any volatile acid or base. Since either an acid or alkali is introduced at the end of the reaction, it is possible to use this easy system with either a phosphate or bicarbonate buffer. The disposable center well can easily be cut off when transferred to a liquid scintillation counting vial. The sidearm flask enables syringe needle entry without disturbing established conditions. Center well is 70mm in length. Approximate overall height x width is 50 x 31mm. Rubber stopper provides a double seal and has an off-center hole for the insertion of the center well.
