US 5,104,807 A · Analyzing apparatus in which liquid can be stirred and analyzing method thereof

Abstract

An analyzing apparatus includes a turntable, and a plurality of reaction containers which are arranged on the turntable. This turntable is intermittently rotated so that the train of reaction containers is alternately in a conveyed state and a stopped state. The outer walls of part of the reaction containers in the train of reaction containers are in contact with a fixedly provided friction flange, while the remaining reaction containers in the train of reaction containers is not in contact with the friction flange. Since the reaction containers located in an area where they make contact with the friction flange are conveyed while they are contacting with the friction flange as the turntable is rotated, the motion of the turntable is transmitted to the reaction containers, and the reaction containers are thereby rotated on their own axes so as to allow the reaction liquid in the containers to be stirred. The rotation of the reaction containers on their own axes is stopped when they reach an area where they do not make contact with the friction flange. After the rotation of the reaction liquid in the reaction containers has been substantially stopped, the light measurement of the reaction liquid is performed using a photometer.

Dependent claims

An apparatus for analyzing the contents of a plurality of containers, each of said containers having an axis of rotation and an outer periphery, comprising:

means for holding said plurality of containers for accommodating a liquid to be stirred therein about said axis of rotation;
fixed container rotating and non-rotating areas;
drive means for driving said means for holding to move said plurality of containers through said container rotating and non-rotating areas;
transmitting means for transmitting motion of said means for holding caused by said drive means to a rotational force acting on said containers, said transmitting means including fixed flange means in said container rotating area for frictionally engaging said plurality of containers to cause each of said containers to rotate on its said axis in said container rotating area;
and
a photometer for irradiating each of said plurality of containers with a light beam in said non-rotating area.
