Dispensing Nozzle for Autoanalyzer, Autoanalyzer Equipped with the Nozzle, and Method for Producing Dispensing Nozzle for Autoanalyzer

摘要

In an autoanalyzer for analyzing a specimen such as urine and blood, protecting a measurement value of analysis from influence of a dispensing nozzle repeatedly used. For this purpose, a phosphonic acid derivative or a phosphoric acid derivative is chemically adsorbed on the surface of the dispensing nozzle. In this manner, a molecular layer for suppressing adsorption of biopolymers or adhesion of a specimen per se is formed on the nozzle surface to prevent accuracy of analysis from being influenced.
