SAMPLE CELL FOR FLUID ANALYSIS SYSTEM
First Claim
1. A cuvette comprising:
- a first window piece;
a second window piece;
a spacer positioned between the first window piece and the second window piece to provide a gap between the first window piece and the second window piece; and
a first clamshell piece and a second clamshell piece positioned on opposite sides of the window pieces, wherein the first and second clamshell pieces are secured to each other to provide support to the first and second window pieces.

Abstract
Systems and method are disclosed for determining a concentration of an analyte (e.g., glucose) in a fluid (e.g., blood). The system can draw blood from a patient and deliver the blood to a sample cell. A centrifuge motor can spin the sample cell to separate the fluid into a plurality of components (plasma, red blood cells, etc.). A particular component of the fluid (e.g., plasma) may be positioned at a sample portion of the sample cell after centrifuging such that the concentration of the analyte is measured in the particular component of the fluid (e.g., plasma). The sample cell can include a cuvette that has two window pieces sandwiched between two clamshell pieces, and where the sample portion of the sample cell is defined by a gap between the window pieces.
