    Abstract: There are provided a sample cooling device capable of effectively removing moisture in the air inside an accommodating chamber where a sample container is accommodated, and of preventing a problem caused by occurrence of frost, an autosampler provided with the same, and a sample cooling method. A first driving process of setting a set temperature of a dehumidifier section to at or below the freezing point, and a second driving process of stopping driving of the dehumidifier section or of raising the set temperature of the dehumidifier section to above the freezing point after the first driving process is performed over a predetermined period of time are performed. Thus, the set temperature of the dehumidifier section may be made to at or below the freezing point by the first driving process, and moisture in the air inside the accommodating chamber may be made to temporarily attach to the dehumidifier section as frost and then be melted by the second driving process and be collected as water.

    Abstract: A cell collecting device include a pipette tip that sucks substances in a cell culture container, a first valve connected to the pipette tip through a first flow path, a first pump connected to the first valve through a second flow path, and a second pump connected to the first valve through a third flow path. In a remove mode, the first valve is switched to connect the first flow path and the second flow path to each other and disconnect the third flow path, and the first pump is driven to discharge waste in the cell culture container, that has been sucked from the pipette tip, from a drain of the first pump through the first flow path and the second flow path, and in a picking mode, the first valve is switched to connect the first flow path and the third flow path to each other and disconnect the second flow path, and the second pump is driven to suck cells in the cell culture container using the pipette tip.

    Abstract: The auto-sampler for chromatographs includes a sampling needle, a pipe, a pump portion, and a connecting mechanism configured to connect the sampling needle and the pipe. The connecting mechanism includes a first component fixed to the sampling needle, a second component fixed to the pipe, a fixing component, and a packing. The fixing component fixes the first component and the second component using screwing of screws while the end surface of the sampling needle and the end surface of the pipe are in contact with the packing. As a result, dead volume at the connecting portion between the sampling needle and the pipe is reduced.

    Abstract: A cell picking device includes a sucker having a pipette tip attached to a tip portion of the sucker and is used to suck the cell from a tip of the pipette tip, a driver configured to cause the sucker to perform a suction operation and move the sucker in a horizontal-plane direction and an axial direction of the pipette tip with the sucker inclined with respect to a vertical direction. A controller moves the sucker such that the tip of the pipette tip moves in a horizontal direction while being in contact with a bottom surface of the container installed on the sample mounting stage in a predetermined position on the sample mounting stage to desorb a cell arranged in the predetermined position from the bottom surface of the container, and suck the cell desorbed from the bottom surface of the container from the tip of the pipette tip.

    Abstract: The sample plate has a principal plane in which a plurality of wells is arranged. The sample plate has a plurality of through-holes each allowing a sampling needle to pass through in a region of the principal plane where the wells are not provided, and positions of the wells and positions of the through-holes are designed such that when two pieces of the sample plates are arranged up and down with a predetermined positional relationship in a state in which respective principal planes are arranged in parallel each other, the through-holes of the sample plate arranged on an upper side is arranged at positions directly above respective wells of the sample plate arranged on a lower side.

    Abstract: A cell picking device includes a stage, a sucker, a driver, a work content receiver, a registrar and a device controller. A sample container is placed on the stage. The driver is provided to execute sample scraping work and sample sucking work using a pipette tip attached to the sucker. In a case in which selection of work contents of the driver is received by the work content receiver, a work procedure including the received work contents of the driver is registered by the registrar. The work of the driver is controlled by the device controller in accordance with the registered work procedure.

    Abstract: An autosampler is switched selectively between an injecting mode where a sampling flow path is incorporated into an analysis flow path of a liquid chromatograph and a loading mode where the sampling flow path is not incorporated into the analysis flow path and injects a sample into the analysis flow path at a position farther upstream than a separation column by being switched to the injecting mode with the sample held in the sampling flow path, and includes a clog determiner configured to acquire a sending liquid pressure of a liquid sending pump that sends a mobile phase in the analysis flow path, obtain a variation value of the liquid sending pressure when the injecting mode and the loading mode are switched and determine presence or absence of a clog in a system incorporated into the analysis flow path in the injecting mode based on the obtained variation value.

    Abstract: A first mixer mixes solvents therein. A second mixer has a capacity different from that of the first mixer, and mixes solvents therein. A first separation column is associated with the first mixer. A second separation column is associated with the second mixer. A first valve enables switchover between a first communication state in which the first mixer and the first separation column communicate with a detector, and a second communication state in which the second mixer and the second separation column communicate with the detector. Only by switching the first valve, it is possible to switch between the first communication state and the second communication state. The internal capacity of a flow channel in the first communication state differs from that in the second communication state. Therefore, it is easy to perform analysis with different internal capacities.
