ABSTRACT:
An apparatus for measuring velocity of chemical reaction by detecting change in light absorbance which stands in proportional relation with time, which comprises arranging plural samples at regular spacings, advancing said samples intermittently at constant intervals, detecting the absorbances with two colorimetric detecting means crossing said samples and measuring the difference between the absorbences thereby determining the reaction velocity of said samples.
