An analysis unit for quantitating detection target substances bound to antibodies includes wells and inclination parts. The wells each have a hole-like shape defined by an opening, an inner circumferential surface, and a bottom. The inclination parts each have an inclined surface connected to the inner circumferential surface and inclined downward such that whose height with respect to the bottom decreases as a distance from an outer circumferential side of the well increases.

Analysis unit, washing device, and washing method

The dispensing unit includes a disc, a cartridge, and a dispensing holder. The disc has a disc shape and includes a track region provided with recesses and projections alternately arranged in a radial direction. The cartridge includes a penetration hole, and a well is formed by the penetration hole and the track region in a state in which the cartridge is attached to the disc. The dispensing holder includes a holding part to be inserted into the penetration hole, and a guide hole penetrating the holding part. The guide hole has a truncated cone shape in which a first opening diameter on the holding part side is smaller than a second opening diameter on a side opposite to the holding part, and a center line of the guide hole is located on a line passing through the center of the disc and the center of the well.

Dispensing unit

A washing apparatus includes a stage, a suction nozzle, and a control unit. On the stage, an analytical unit is mounted. In the analytical unit, a well having a hole shape including a bottom surface and an inner peripheral surface is formed. The suction nozzle sucks a solution in the well. The control unit, after controlling the suction nozzle to sucks the solution in the well, controls the stage to rotate the stage on which the analytical unit is mounted at a predetermined speed of rotation, and controls the suction nozzle to suck a residue of the solution existing in the well.

Washing apparatus and washing method

A magnet structure includes first and second magnet units. The first magnet unit is provided with a first magnet fixing section that includes a first surface and a first magnet having a first polarity on the first surface's side. The second magnet unit is provided with a second magnet fixing section that includes a second surface and a second magnet having a second polarity on the second surface's side, the second polarity being an opposite polarity to the first polarity. The first and second surfaces are located next to one another on the same plane to form a magnetic attachment surface which is magnetically attached to a magnetically-attached object. The second magnet unit is supported by the first magnet unit so as to move in a predetermined range.
