Automatic analytic device

Abstract

Abstract PURPOSE:To constitute so as to be able to analyze the sample solution in the fixed warming time even when the measuring time is changed by making the reaction disc to turn round at a step angle in proportion to the time of measuring sample solution. CONSTITUTION:On the line divided into forty equal parts of the central angle of the disk-shaped reaction disk 1 40 holes 2 for reaction containers are provided and each hole 2 is arranged with a reaction container 3, whereby the reaction disk 1 turns round intermittently with the step angle theta of 9 deg.. The reaction container 3 accommodating sample solution turns round to the reagent injecting position 5 through 4 times of step feed and meanwhile the reaction container 3 passes through the constant temperature bath 7 to be warmed and cultivated in the fixed warming hour T. The bottom figure shows the case of analyzing spending double measuring time being turned round intermittently with double step angle 2theta. Accordingly the reaction container 3 performs partial injection and measurement alternately making the warming hour same as in the case of the upper Figure.
