Patent Number: 7,820,114

Title: Reaction container for chemical analysis with the controlled surface property

Abstract: A highly reliable reaction container capable of restraining an initial detection failure (bubble attachment), and a biochemical and/or immunological automatic analyzer loaded with the reaction container. In a reaction container made of a synthetic resin and used for receiving a biological sample and a reagent, developing a biochemical and/or immunological reaction between the biological sample and the reagent, and measuring proceedings of the reaction and/or the state at a predetermined point in time by optical means, an inner wall surface of the reaction container in contact with the biological sample, the reagent, and a reaction product of the biological sample and the reagent has a critical surface tension of not smaller than 25.0 mN/m, or a contact angle between the inner wall surface of the reaction container and a solvent of a reaction solution is not larger than 60 degrees.
