摘要： A biological material measuring instrument is described. The biological material measuring instrument includes a rotating body and a main body. The rotating body includes one or more cartridge holders having cuvettes in which a reagent and an analyte in a sample react. The main body includes a pair of light-emitting parts and light-receiving parts to optically measure the analyte in the sample. The rotating body further includes a light-emitting optical waveguide for guiding the light of the light-emitting parts to the cuvette, and a light-receiving optical waveguide for guiding.

摘要： An apparatus is for moving a sample holder on a platform from a loading position where the sample holder can be removed from the platform to a locked position where the sample holder is securely held. The sample holder is configured to rest on wheels within a recessed portion on the platform. The apparatus is configured such that: (i) movement of the platform from the loading position to the locked position causes a vertical clamp to lower down on top of the sample holder, and a horizontal clamp to be pressed to an outer periphery of the sample holder; and (ii) movement of the platform from the locked position to the loading position causes the vertical clamp to rise above the sample holder, and the horizontal clamp to be moved away from the outer periphery of the sample holder.

摘要： Disclosed is a chemiluminescence measurement apparatus that includes: a support member configured to support a cartridge for measuring a test substance contained in a specimen by chemiluminescence measurement; a motor configured to rotate the support member so as to rotate the cartridge such that a process required for the chemiluminescence measurement proceeds in the cartridge; and a light receiver configured to receive light generated by chemiluminescence in the cartridge that is supported by the support member rotated by the motor. The cartridge supported by the support member and a light receiving surface of the light receiver are disposed inside a dark space surrounded by a light-shielding portion, and the motor is disposed outside the dark space.

摘要： A fluid processing device includes a detection assembly having a light source, an adjustment system, and a light detector. The light source is associated with a component of the fluid processing device, provided in an initial position with respect to said component of the fluid processing device, and configured to emit a light. The adjustment system is associated with the light source and configured to adjust the position of the light source. The light detector is configured to receive at least a portion of the light from the light source and generate a signal indicative of the amount of light received by the light detector. The fluid processing device further includes a controller configured to receive the signal from the light detector and control the adjustment system to move the light source to a monitoring position based at least in part on the signal.

摘要： A device and method for separating serum or plasma from blood cells in a whole blood specimen. The present invention uses a cap with a reservoir, such that blood cells are packed into the cap when the specimen container is centrifuged. When the cap is removed, the blood cells are also removed, and the serum or plasma is left in the specimen tube where it can be readily extracted by a pipette which is able to reach all the way to the bottom of the specimen tube minimizing the dead volume.

摘要： A test apparatus and a control method thereof are provided. The test apparatus is configured to test a sample in a reactor. The test apparatus includes at least one light emitter configured to emit light to chambers of the reactor, a light receiver configured to receive light passed through the chambers while scanning the chambers, and a processor configured to determine a position or an area of a chamber among the chambers, based on light receiving positions of the light receiver, and respective intensities of the received light. The processor is further configured to measure an optical density of light passed through the determined position or the determined area of the chamber.
