Abstract:
1. A capillary array unit comprising: a capillary array including one or more capillaries capable of being filled with an electrophoresis medium therein; a frame for holding the capillary array; and a load header for supporting cathode ends of the capillaries, wherein: the frame comprises a plurality of separators for separating and holding the capillaries in a predetermined shape by the capillaries passing through the separators, the capillary array comprises a linear portion projecting from the frame and a remaining portion held by the separators provided on the frame, the linear portion having a capillary head at an extreme end and a detection unit adjacent to the capillary head, the remaining portion having the cathode end opposite to the capillary head, the remaining portion of the capillary array includes a first portion which is held in a substantially linear shape by at least a first separator and a second separator adjacent to the detection unit, and a second portion which is held in a curved shape by at least a third separator spaced from the first and second separators, the capillary head, the detection unit, the first separator and the second separator are disposed along one linear line, and, the separators are disposed on the frame so that when the capillary head is moved in a direction along the linear portion, the linear portion and the first portion of the remaining portion which is held in a substantially linear shape move freely in a direction along the linear portion.
