Abstract

A flow cell including a flow cell bod having a flow path formed therein; an optically transmissive member disposed at a part wherein light from the light source is incident into, or emitted from, the flow path; a shock absorbing member that is disposed between the optically transmissive member and the cell body; an elastic member, made from a metal material, for pressing the optically transmissive member toward the cell body side; and a fastening tool, attached to the cell body, for positioning the elastic member.

First claim

What is claimed:

1. A flow cell comprising:
a cell body having a flow path formed therein;
an optically transmissive member disposed at a part within the flow path wherein light from a light source is incident or emitted;
a sealing member disposed between the optically transmissive member and the cell body;
an elastic metal member having a disk spring shape, for pressing the optically transmissive member in the direction of the cell body; and
a fastening tool that is attached to the cell body for positioning the elastic metal member,
wherein the fastening tool is a fastening screw, and the elastic metal member is integrated with the fastening screw.

2. A flow cell as set forth in claim 1 , wherein:
the optically transmissive member is a lens or a window plate.

3. A flow cell as set forth in claim 1 , wherein:
the fastening tool is a fastening screw having a hole at the light path of the light.

4. A flow cell as set forth in claim 1 , wherein:
the elastic metal member has a truncated conical disk spring shape.

5. A flow cell as set forth in claim 1 , wherein:
the elastic metal member is a compression spring.

6. A flow cell as set forth in claim 1 , wherein:
a shock absorbing gasket made from resin is disposed between the optically transmissive member and the elastic metal member; and
the elastic metal member presses the optically transmissive member toward the cell body side through the shock absorbing gasket.
