Abstract: An outside opening of each aperture of a plurality of counting chambers for performing particle counting based on the electric resistance method is connected to suction pump through a confluent piping. Liquid supplying part supplies an additional liquid to the counting chamber side after completion of counting of counting chamber, so that the liquid level of sample liquid of counting chamber will not descend to aperture or a predetermined liquid level.

Abstract: A particle analysis apparatus for flow cytometry, which contains a flow cell having a flow channel for flowing a sample solution containing particles to be analyzed, a light source device for emitting an irradiation light, an optical system for irradiating the irradiation light on an irradiation segment in the flow channel, and a light receiving device for detecting the light obtained thereby. A light source of the light source device is LED, and an electrode formed on a light extraction surface thereof mainly contains a plurality of electric conductor lines arranged in parallel to each other.

Abstract: The analysis apparatus of the present invention determines sufficiency/insufficiency of the test liquid by, before aspiration of the test liquid in container with the nozzle, comparing the amount of the test liquid determined based on the descending distance of the nozzle from the position at which the tip of the nozzle contacts the liquid surface of the test liquid, with the proper amount of the test liquid for the container identified by the container identification system.

Abstract: A substrate measuring stage used for a curve measuring system measuring a curve of the substrate and an ordinary measuring system measuring each of or one of a physical quantity and a chemical quantity of the substrate other than the curve, may include the mounting board movable between an ordinary measurement position for the ordinary measuring system and a retreat position away from and downward of the ordinary measurement position; the plurality of support pins insertable into through-holes provided in the mounting board and fixed to a curve measurement position for the curve measuring system; and a drive mechanism vertically moving the mounting board between the ordinary measurement position and the retreat position. The curve measurement position is set between the ordinary measurement position and the retreat position.

Abstract: To improve position reproducibility of support pins 3 and to prevent a displacement of a substrate in a horizontal direction during movement of a position of the substrate between a position on a mounting board 2 and a position on the support pins 3.
