To prevent a foreign matter occurring in circulation water and to improve the reliability of a device by applying germ-preventing and fungus- preventing paints to the surface of an armor-system cover for preventing, for example, microbe and fungus that are one of the causes for contamination from being generated.
A germ-preventing and fungus-preventing paint 10 is applied to a reagent cover 3. Further, the germ-preventing and fungus-preventing paint 10 is applied to a non-painted reagent cover 11 (injection forming), thus compensating for the germ-preventing and fungus-preventing effect loss due to the fall-off of the paint caused by the deterioration of the paint and scratches and hence maintaining various kinds of cover washing for a long time.
