ABSTRACT:
A transfer unit for transferring members such as reaction vessels having an upper end opening or dispensing tips or the like includes at least one arm pivotally movable about a shaft and a holder mounted on the arm for detachably supporting the member to be transferred. The holder is provided with a rod portion having a distal end adapted to be fitted in the upper end opening of the member to be transferred, a rod holding portion slidably and elastically supporting the rod portion and a guide portion surrounding the rod portion thereabout and sliding along the axis of the rod portion to release the fitting of the member from the distal end of the rod portion. The guide portion is formed with at least two elongated apertures extending in parallel with the axis of the rod portion, and the rod portion is provided with protrusions fixed thereto and extending through the elongated apertures to regulate the movement of the guide portion. By applying such a transfer unit to a chemicobiological or immunity analyzing apparatus, the analyzing operation can be performed at a higher speed with a higher efficiency and a particularly compact analyzing apparatus is possible.
