A genetic detection and determination apparatus which detects or determines genetic information, provided with a reaction container having a reaction vessel, including: a container set portion on which the reaction container is set; a moving mechanism which moves the container set portion along a track; a reaction vessel dividing portion which divides the reaction vessel into a plurality of reaction chambers by deforming the reaction vessel; a heating and cooling portion which heats and cools the reaction container; and a measuring portion which is movable above the container set portion in parallel to an upper surface of the reaction container provided on the container set portion and which measures a reaction within each of the reaction chambers.

Genetic detection and determination apparatus and method, gene reactor, and incubator

An optical measurement apparatus using an optical fiber to measure the characteristic of an object to be measured arranged along the circumference of a circle includes a first pulley, a second pulley which is turnable on its own axis at a second angular velocity while revolving about the first pulley at a first angular velocity, and the optical fiber which is held by the second pulley and projects detection light on the object to be measured and receives reflected light from the object to be measured. The first angular velocity and the second angular velocity are the same in magnitude and opposite in the direction. Occurrence of a twist in the optical fiber is suppressed, and therefore, the optical measurement apparatus is capable of measuring the characteristics of the object to be measured with high accuracy.

Optical measurement apparatus

The reaction chip of the present invention has a plurality of recessesconstituting a part of a reaction container and a groove constituting a part of a channel formed on at least one of one face of a first base material (resin base material) and one face of a second base material (metallic base material) and a notchshowing a gradual increase in width and a gradual increase in depth from one faceof the base material toward an inner wall surfaceof the recess is formed on an edge of at least one recess in an extending direction of the groove. One face of the first base material and one face of the second base material are stuck together opposite to each other to form the plurality of reaction containers and the channel.

A transferred object rotating device includes a mounting plate having an opening corresponding to a shape of a transferred object and being capable of moving from a mounting position to a rotating position, a boost unit capable of moving up to pass through the opening of the mounting plate in the rotating position, and a rotation plate capable of rotating about a power transmission shaft. The mounting plate moves to the rotating position after the transferred object is mounted on the mounting plate to close the opening. The transferred object is lifted by upward movement of the boost unit. The transferred object rotates while being sandwiched between the boost unit and the rotation plate. The transferred object mounted on the mounting plate in the mounting position can be transferred to the rotating position by the mounting plate, and rotate in the rotating position.
