PROBLEM TO BE SOLVED: To provide a cell for optical measurement capable of preventing a sample from leaking out to the outer surface side of a fixed member.SOLUTION: A sample leaking out through a clearance between a body 1 and a window member 2 from the inside of a sample flow channel 11 is recovered via a recovery passage 14 formed on the body 1. Since the sample can be recovered before reaching the outer surface side of a fixed member 4, the sample can be prevented from leaking out to the outer surface side of the fixed member 4. By the constitution that the recovery passage 14 communicates with a screw part 13 for fixing the fixed member 4 by tightening it, with the fixed member 4 fixed to the body 1, the sample being about to leak out to the outer surface side of the fixed member 4 along the screw part 13 of the body 1 can be recovered via the recovery passage 14 communicating with the screw part 13. |
