Abstract: A sample separator (1) comprising an accommodation part (10) that accommodates a separation medium for electrophoresis, and a support (20) formed from a porous material. The accommodation part (10) includes an internal space (10c) filled with the separation medium, and is provided with a supply port (10a) and discharge port (10b) that are in communication with the internal space (10c). The support (20) is provided so as to block the discharge port (10b).

Abstract: An automatic electrophoresis apparatus includes: a transfer film supply unit configured to supply a transfer film; a sample transfer unit configured to transfer a sample separated by electrophoresis to the transfer film; a post-processing unit configured to perform processing of the transfer film, to which the sample has been transferred, to obtain a transfer image thereof; and a transporting unit configured to transfer the transfer film along a transporting direction between each of units. The transfer film is provided with guide members that are configured to guide and support along the transporting direction.

Abstract: There is provided an electrophoresis instrument capable of easily performing a separation of a biological sample by isoelectric focusing with excellent reproducibility. An electrophoresis instrument (10) includes an electrophoresis chamber (1) in which a sample separation medium (42) for separating the biological sample by electrophoresis is installed. A depression (2) for injecting a sample solution that includes the biological sample is provided on an installation surface (1a) on which the sample separation medium (42) of the electrophoresis chamber (1) is installed.

Abstract: A sample separation/adsorption appliance (100) according to one embodiment of the present invention includes: a first buffer solution tank (103) equipped with a first electrode (101) and used for holding a first buffer solution; a second buffer solution tank (104) equipped with a second electrode (102) and used for holding a second buffer solution; a sample separation section (110) that holds a sample separation medium (131) for separating a sample; and a conductive section (120) that holds a conductive medium (133), wherein: the sample separation medium (131) and the conductive medium (133) are in contact with the sample adsorption member (132), respectively, on the opposite sides thereof; an end of the sample separation medium (131) opposite to an end being in contact with the sample adsorption member (132) is connected to an inside of the first buffer solution tank (103); and an end of the conductive medium (133) opposite to an end being in contact with the sample adsorption member (132) is connected to an
