摘要： In a chemical analysis element cartridge, chemical analysis element pressing mechanism is inserted into a cartridge body to press a stack of chemical analysis elements in the cartridge body toward an element take-out port formed in one end of the cartridge body. The element pressing mechanism includes a stopper to be engaged with an engagement teeth formed on an inner wall surface of the cartridge body and a pressing member which presses the stack of the chemical analysis elements toward the element take-out port under the force of a coiled spring. The stopper has a slider member which is slidable relative to a shaft portion of the pressing member and the coiled spring is disposed around the slider member with its one end in abutment against the pressing member and its the other end retained by a spring retainer portion formed on one end of the slider member. A bulged portion on the outer surface of the slider member aligns an effective center of an envelope defined by the end of the coiled spring with the effective center of the spring retainer portion.

摘要： A nozzle of a dispenser is filled with a coagulative liquid specimen. Then, the liquid is drawn into the dispenser such that a lower surface of the liquid is spaced from the lower end of the nozzle by a distance which is not smaller than the inner diameter of the nozzle. The liquid is maintained at this position before the next discharging operation is carried out to discharge a predetermined amount of coagulated test liquid onto a chemical assay slide for incubation of the test liquid.

摘要： A sample liquid is sucked into a nozzle which is mounted at a front end of an arm. Then the arm is moved down to a position where the sample liquid is discharged from the nozzle so as to form a drop on the lower end of the nozzle. Thereafter the arm is further moved down at a speed not higher than 40 mm/sec to a position where the drop comes into contact with a chemical analysis element.

摘要： A dry analytical substantially flat film chip for use as an analytical element composed of a support, at least one reagent layer and a spreading layer laminated in this order. The chip is suitable for use as is as an analytical element for liquid samples. The chip further has means for restraining a liquid sample applied to its surface from spreading beyond a predetermined area of the surface. The restraining means may be a fused nonporous area of the spreading layer or may be a portion or area of the spreading layer which has been clogged with a hydrophobic or lipophilic material to render it nonporous. The inventive film chip, in addition, provides means for preventing fraying of the edges of the porous spreading layer as well as the prevention of the generation of fiber dust during cutting of the chip.
