PURPOSE:To obtain the small-diameter pipe which can be mass-produced and is small in receptor use quantity and where inexpensive receptors are fixed by fixing a 1st receptor which is coupled singularly with an analyte on the internal wall of the small- diameter part of the small-diameter pipe. CONSTITUTION:The 1st receptor which is coupled singularly with the analyte as a material to be measured is fixed on the internal wall of the small-diameter pipe part 2 of the small-diameter pipe 1 in a pipette chip shape which increases in diameter from the thin-diameter part 2 for pH electrode insertion provided atop to the rear end. Further, small-diameter pipes 1a - 1d are coupled in series by the fixing method for receptors and a suction means is connected to the rear end opening of the small- diameter pipe 1a of the final part; and a buffer solution obtained by dissolving the 1st receptor coupled singularly with the analyte to be measured is sucked by the suction means from the tip of the small-diameter part of the small-diameter pipe at the tip part and thus the 1st receptor is fixed on the internal wall of at least the small-diameter pipe part of each small-diameter pipe. Consequently, homogeneous small-diameter pipes can be manufactured in quantities at a time. Further, the small- diameter pipes become inexpensive because of the use quantity of receptors is small. |
