GRIPPING MECHANISM

摘要

[PROBLEMS] It is an object to provide a gripping mechanism that enables inhibition of possible static electricity and contamination in a gripping object such as a reaction container, while enabling the orientation of the gripping object to be stabilized. [MEANS TO SOLVE PROBLEMS] The gripping mechanism is a gripping mechanism for gripping a cuvette T, the gripping mechanism comprising: a sandwiching section 50 for holding the cuvette T in a laterally sandwiching manner; a pressing section 60 for pressing downward an upper end surface of the cuvette T held in a sandwiching manner by the sandwiching section 50, wherein the pressing section 60 is arranged such that, with the cuvette T being held in a sandwiching manner by the sandwiching section 50, a central axis of the cuvette T along a vertical direction coincides mutually with a central axis of the pressing section 60 in the vertical direction.
