    Abstract: The present invention relates to a dispensing cylinder, and a dispensing device and a dispensing treatment method using the dispensing cylinder. An object of the present invention is to provide a compact, easily handled, and highly accurate dispensing cylinder capable of performing a dispensing treatment for both a minute amount of liquid and a large amount of liquid using a single mechanism, and a dispensing device and a dispensing treatment method using the dispensing cylinder.
    The dispensing cylinder includes: a cylinder having a cavity therein; a nozzle provided at one end of the cylinder, having a through hole communicating with the cavity and extending in an axial direction of the cavity, and making a dispensing tip attachable to an outside thereof; and a plunger provided so as to be slidable in the cavity in the axial direction. The cavity has a large diameter region having a large diameter inner peripheral surface and a small diameter region provided so as to be closer to a nozzle than the large diameter region and having a small diameter inner peripheral surface. The plunger has a thick shaft portion provided so as to be slidable in the large diameter region and a thin shaft portion protruding from a distal end of the thick shaft portion in the axial direction and provided so as to be slidable in the small diameter region.

    Abstract: The present invention relates to a photometric dispensing nozzle unit, a photometric dispensing apparatus, and a photometric dispensing method, and an object of the present invention is to provide a photometric dispensing nozzle unit, a photometric dispensing apparatus, and a photometric dispensing method, preventing an increase in apparatus scale and having a simple structure to be easily handled.
    The present invention includes: a nozzle that performs suction/discharge of gas through a distal end opening and can have a dispensing tip attached thereto; a light guide end portion that is provided in the nozzle and can receive or irradiate light at a distal end of the nozzle; a dispensing cylinder including a cylinder having a cavity therein, a plunger that is slidable in the cavity, and a suction/discharge port that performs suction/discharge of gas; a suction/discharge flow path that passes through the nozzle and communicates with the suction/discharge port and the distal end opening of the nozzle; and a light guide path optically connected to the light guide end portion through the nozzle but not through the dispensing cylinder.
