PROBLEM TO BE SOLVED: To provide an instrument for biochemistry, capable of reducing the amount of adsorption of matters originating in a living body. SOLUTION: The instrument for biochemistry is made up of a resin material chiefly having a polar group at its side chain. It is characterized by satisfying following relation: 0.3≤B/A, wherein A and B respectively represent spectral intensity values of C-C bond and C-O bond obtained by measuring an inner surface of the instrument for biochemistry by using an X-ray photoelectron spectroscopy. It is preferable that the above resin material is an ethylenic copolymer. COPYRIGHT: (C)2005,JPO&NCIPI
