Abstract: Provided are an automated analyzer for analyzing a substance contained in an unknown sample and a liquid reservoir, the analyzer and the reservoir being capable of saving users' operation without remarkably increasing the number of components. A flow path outlet of an overflow portion of the liquid reservoirs projects closer to the inner circumferential side of a drain flow path than to an inner circumferential surface side of an outer wall of the drain flow path serving as a destination to which liquid overflows. In addition, the flow path outlet projects so as to come into contact with an outer wall of the inner pipe. The flow path outlet of the overflow portion projects into the drain flow path so as to be located below an upper end of the outer wall of the drain flow path.

Abstract: Provided are an electrode, an electrolysis cell, and an electrochemical analyzer that improve the long-term stability of analysis data. A working electrode, a counter electrode, and reference electrode are disposed in an electrolysis cell. The working electrode is obtained by forming a lead wire in a composite material having platinum or a platinum alloy as a base material, in which a metal oxide is dispersed, or in a laminated material obtained by laminating a valve metal and platinum such that the cross sectional crystal texture in the thickness direction of the platinum is formed in layers and the thickness of each layer of the platinum is 5 micrometers or less. The metal oxide is selected from among zirconium oxide, tantalum oxide, and niobium oxide, and the metal oxide content of the platinum or the platinum alloy is 0.005 to 1 wt % in terms of the zirconium, tantalum, or niobium metal.
