<p><P>PROBLEM TO BE SOLVED: To provide an automatic analyzing device capable of solving the problem that accurate dispensing of a minute amount of a sample requires to secure an appropriate and accurate clearance between a sample probe and a reaction vessel at dispensing time, but a height of a bottom surface of each reaction vessel must be measured to control a sample probe lowering amount in dispensing a minute amount because the height of the bottom surface of the reaction vessel varies due to various factors, and accurately measuring the height of the bottom surface of the reaction vessel at low cost and with a simple mechanism, and maintaining a microscale dispensing accuracy. <P>SOLUTION: The device uses a liquid level detecting function to detect the height of the reaction vessel, and controls a position of the sample probe, while operating the sample probe. By installing a grounded conductive member on the sidewall of the reaction vessel, the height of the bottom surface of the reaction vessel is measured and corrected for each reaction vessel without setting a threshold value. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT</p> |
