Abstract
An automatic analyzer for analyzing samples, such as urine and blood, is adapted so that analysis measured values are not affected by carry over by a repeatedly used dispensing nozzle. Coating the surface of the dispensing nozzle with a chemisorbed polyethylene glycol derivative forms a molecular layer that inhibits the adsorption of biopolymers, to reduce carry over by the dispensing nozzle.
