Abstract: A cartridge sealed from an external air is used to enable mixing with a reagent, agitating, purification, reaction, etc. Provided inside the cartridge sealed from the external air are a chamber for the reagent to be transported, a chamber to which the reagent is transported, and the chambers are connected by a liquid transport channel. A groove is made in a cartridge body and a membrane as an elastic body is pasted onto the groove to form the liquid transport channel. Air pressure is given to the membrane to change the volume of the liquid transport channel and thereby move the fluid inside. The inlet of each chamber has a valve function to move the fluid inside in a desired direction according to change of the liquid transport channel. This enables transportation of the liquid inside the cartridge sealed from the external air.

Abstract: Provided is an analyzer capable of reducing the amount of wasted reagents and shortening time required for solution sending, thus increasing throughput for analysis. A microsyringe sucks a minimum required amount of reagent that is substantially the same amount of capacity of a flow cell to a sampling nozzle. Then, the sampling nozzle is inserted into an injection port of the flow cell, and the reagent is injected into the flow cell by driving the microsyringe. The inside of the sampling nozzle is cleaned by moving the sampling nozzle to the cleaning tank and ejecting cleaning water from the sampling nozzle, and the outside of the sampling nozzle is cleaned by spraying cleaning water from an inner wall of the cleaning tank.

Abstract: A cartridge sealed from ambient air is used to send a liquid without causing the liquid to contact the fluid inside the cartridge. Inside of the cartridge 1 sealed from ambient air are provided chambers that send and receive reagents, and an elastic body membrane 51 is attached to the bottom surface. The cartridge main body 51 does not have a groove or anything else that becomes a channel, and the membrane 51 is not bonded to portions that become channels. A channel, not formed in a normal state, is formed upon deforming the membrane 51 under air pressure in the unbonded portion, and the fluid is moved inside. A valve function is provided at an inlet of each chamber, and the fluid is internally moved in any direction with channel deformation.

The dispensing device of the present invention includes a dispensing nozzle 10 that aspirates and discharges liquid, a lid opening and closing part 26 that projects downward to be lower than the dispensing nozzle 10, and a drive unit that makes the dispensing nozzle 10 and the lid opening and closing part 26 drive in the vertical direction, in which the dispensing nozzle 10 drives in the vertical direction independently of the lid opening and closing part 26. The dispensing device that achieves both of preventing cross-contamination between the reagents and attaching the lid to the reagent container can be provided.

Abstract: A cartridge sealed from an external air is used to enable mixing with a reagent, agitating, purification, reaction, etc. Provided inside the cartridge 1 sealed from the external air are a chamber 38 for the reagent to be transported, a chamber 39 to which the reagent is transported, and the chambers are connected by a liquid transport channel. A groove is made in a cartridge body 30 and a membrane 31 as an elastic body is pasted onto the groove to form the liquid transport channel 36. Air pressure is given to the membrane 31 to change the volume of the liquid transport channel 31 and thereby move the fluid inside. The inlet of each chamber has a valve function to move the fluid inside in a desired direction according to change of the liquid transport channel. This enables transportation of the liquid inside the cartridge sealed from the external air so that mixing with the reagent, agitating, purification, reaction, etc. can be performed in the cartridge.

Abstract: A grooved noodle includes a noodle string a cross section of which has a parallelogrammic or rectangular basic contour, two grooves extending along the noodle string are provided at symmetrical positions with respect to a center of the cross section of the noodle string, in the cross section of the noodle string, each groove has a pair of first sides that face each other and extend from an opening plane of each groove toward an inside of the noodle string, and a pair of second sides that respectively extend from ends of the first sides in bending directions so as to come closer to each other and are interconnected to form a terminal end of each groove, and a distance from the terminal end to the opening plane of each groove is larger than ½ of a width of the noodle string in a grooving direction.

Abstract: A gamma scanning apparatus includes a moving and fixing mechanism which moves/fixes a housing to a definite position, and a rotating and moving mechanism which moves a fuel assembly vertically in addition to rotating the assembly. A gamma-ray counting circuit measures an output of a gamma-ray detector, and a data collecting/analyzing and controlling apparatus analyzes data output from the gamma-ray counting circuit, in association with data relating to the rotation and movement of the fuel assembly by the rotating and moving mechanism. The rotating and moving mechanism, after fixing the vertical position of the fuel assembly with the housing also fixed, rotates the fuel assembly through 360° with its height kept constant, and during the 360° rotation of the fuel assembly, the gamma-ray counting circuit measures either a time average of count values of the detector during the rotation or an integral value within a fixed time.
