There is provided a bellows type dispensing tip, a bellows type dispensing apparatus, and a method of bellows type dispensing processing that performs highly precise dispensing processing despite having a simple structure. The apparatus comprises; two or more bellows type dispensing tips having; an accommodating section that is capable of accommodating a liquid or gas in the interior thereof surrounded by a wall face, and that has a deformable deforming wall face in a portion of the wall face, and an opening section communicated with the accommodating section, through which the liquid to be suctioned/discharged can flow in and flow out due to expansion and contraction of the interior caused by deformation of the deforming wall face; and a dispensing head that supports the bellows type dispensing tips, and that performs suction/discharge of the liquid into or from the bellows type dispensing tip, by deforming the deforming wall face.

The purpose of the present invention is to provide a control system which, when a sensor is not built in a motor, saves the power of the sensor and increases the life thereof by on/off-controlling power supply to the sensor before and after the operation of the motor, and also to provide an automatic analysis device. The control system 201 is provided with sensors 309a, 309b, 602, 603 for monitoring the operation of a motor and a control mechanism for controlling the operation of the motor. The control mechanism is provided with: a function of starting power supply to the sensors 309a, 309b, 602, 603 before a first predetermined time from the time when the motor starts the rotating operation; and a function of stopping the power supply to the sensors 309a, 309b, 602, 603 after a second predetermined time from the time when the motor terminates the rotating operation.

A liquid is efficiently suctioned and discharged from and to a container formed by a plurality of aligned storing portions for storing the liquid, using a plurality of nozzles. Provided is a liquid suction/discharge device including a container support device for supporting a culture container formed by a plurality of aligned storing portions, and a nozzle support device for supporting a plurality of nozzles in a state in which distal ends of the nozzles are directed downward. The nozzle support device includes a nozzle support member that swingably supports the plurality of nozzles using prescribed parts as support points, and the liquid suction/discharge device further includes a nozzle inclination device for causing each of the nozzles to be inclined with respect to the nozzle support member.

A crude oil displacement method includes partially filling a vessel with treatment fluid and positioning an oil-saturated sample within the treatment fluid. The method also includes adding a solvent system to the vessel above the treatment fluid. In addition, the method includes moving oil from the oil-saturated sample into the solvent system. The method also includes measuring one or more of R, G, B, L, a, b, L, C, H, H, S, B, reflectance, transmittance and wavelength of the displaced oil using a color device. In addition, the method includes determining the amount of displaced oil using the one or more of R, G, B, L, a, b, L, C, H, H, S, B, reflectance, transmittance and wavelength of the displaced oil.

An autosampler includes: a sample cooling unit that is brought into thermally contact with a bottom surface of a sample rack so as to cool a sample accommodated in the sample rack; a condensed water receiver that has at least one hole on a bottom surface thereof, and is provided below the sample rack for receiving water condensed around the sample rack; a discharging passage configured in such a manner that a droplet falling from the at least one hole flows therein.

A robotic assembly associated with gripping an object may determine, using an angle sensor, a relative position of a first gripping arm in relation to a second gripping arm of a robotic assembly. The robotic assembly may separate, using an actuator, the first gripping arm and the second gripping arm of the robotic assembly. The robotic assembly may position the gripping arms around an object, so the first gripping arm and second gripping arm accommodate the object. The robotic assembly may then join the first gripping arm and the second gripping arm until the first roller, second roller, and third roller are in contact with the object. The robotic assembly may apply pressure to the object using a plurality of compression springs between the first gripping arm and second gripping arm allowing the robotic assembly to grip the object.
