Abstract
A control cuvette used for measurement accuracy control in a measuring apparatus for observing a formed element contained in a liquid sample after precipitating the formed element to a bottom surface of a cuvette, wherein an observation pattern representing a shape of the formed element contained in the liquid sample is provided at an observation surface of the control cuvette corresponding to the bottom surface of the cuvette.
Claims19
A control cuvette used for measurement accuracy control in a measuring apparatus configured for observing a formed element contained in a liquid sample in a cuvette after precipitating the formed element to a bottom surface of the cuvette, the control cuvette comprising:
- an observation surface, wherein a predetermined observation pattern including a shape of a formed element contained in a liquid sample in a predetermined cuvette is formed on the observation surface, and wherein the observation surface of the control cuvette corresponds to the bottom surface of the cuvette, and
- wherein the predetermined observation pattern is formed to the observation surface of the control cuvette by capturing an image of the shape of the formed element contained in the liquid sample in the predetermined cuvette and forming the observation pattern including the shape of the formed element whose image has been captured using the predetermined cuvette, to the observation surface of the control cuvette.
A control cuvette used for measurement accuracy control in a measuring apparatus configured for observing a formed element contained in a liquid sample in a cuvette after precipitating the formed element to a bottom surface of the cuvette, the control cuvette comprising:
- an observation window;
- a light entrance section spaced from the observation window;
- and
- an observation surface formed on the light entrance section,
- wherein a predetermined observation pattern including a shape of a formed element contained in a liquid sample in a predetermined cuvette is formed on the observation surface of the control cuvette.
