Abstract: A column accommodation device (1) includes a housing in which a column accommodation space (4) is provided, and a chip column (6) having a plate-shape and having an internal flow path (40) filled with a separation medium (41) is accommodated in the column accommodation space (4). An outer surface of the chip column (6) is provided with openings (42) respectively communicating with both ends of the internal flow path. Inside of the column accommodation space (4) is provided with a guide (18) for guiding the chip column (6) to a predetermined position. The column accommodation device (1) includes a seal device (32) for connecting and releasing pipes (44) to and from the openings (42) of the chip column (6), and a controller (46) configured to perform operation control of the seal device (32), and the controller (46) is configured to fluidly connect the pipes (44) with respect to the openings (42) of the chip column (6) when it is determined that the chip column (6) is arranged at the predetermined position.

Abstract: A solid-liquid boundary detection device 20 is a device for detecting a boundary 141 between a solid and a liquid in a test tube 14, and includes a surface illumination 21, an imaging unit 22, and a boundary detection processor 31. The surface illumination 21 illuminates the test tube 14 from outside. The imaging unit 22 is arranged on an opposite side of the test tube 14 from the surface illumination 21, and captures an image including the boundary 141. The boundary detection processor 31 detects the boundary 141 from the image captured by the imaging unit 22.

Abstract: A cap attaching/detaching device 20 is a device for attaching or detaching a cap 141 in which a screw portion is formed to or from a test tube 14 by rotating the cap 141. A cap grip portion 21 grips the cap 141. A rotation mechanism 22 attaches or detaches the cap 141 to or from the test tube 14 by rotating the cap 141 by rotating the cap grip portion 21. The rotation mechanism 22 has an axial portion 221, and a nut portion 222. The axial portion 221 has an outer peripheral surface on which a screw thread 223 is formed. The nut portion 222 has an inner peripheral surface on which a screw groove 224 to be screwed into the screw thread 223 of the axial portion 221 is formed, and rotatably holds the axial portion 221 in a fixed state. A pitch of the screw thread 223 is the same as a pitch of the screw portion formed in the cap 141.
