Abstract: The invention provides an automatic analyzing machine comprising a unique reaction cup combination for running high volume chemical analyses, such as analyses for sodium, potassium, glucose, creatinine and BUN (blood urea nitrogen). The reaction cup combination includes an aluminum body having at least one flat smooth side. A planar heating element is sandwiched between the flat side and a planar outer sidewall. Within the planar outer sidewall is disposed a reagent inlet conduit coiled or otherwise disposed in planar fashion. By this design, heating of inlet reagent is more efficient and control of the temperature within the reaction cup is more precise. In a preferred embodiment, the reaction cup assembly includes a pair of such heating element and inlet conduit combinations so that the reaction cup can be rinsed with heated water instead of heated reagent. Such a design not only reduces the use of expensive reagent, but minimizes toxic waste disposal needs.
