Abstract
Verification plates for a bacterial endotoxin reader are provided, namely a temperature verification plate (TVP) and optical verification plate (OVP). The TVP has a body configured to be placed on a spindle of said reader and rotated by said spindle. The body has a temperature verification circuit with a temperature sensor and a temperature indicator. The temperature sensor is configured to measure a temperature of the body rotated by the spindle of the reader. The temperature indicator optically represents a value of the temperature measured by the temperature sensor. The temperature indicator is readable by an optical bench of the reader. The OVP has a body with a plurality of apertures located along a periphery that line up with an optical bench of the reader. Light produced by a light source of the reader can pass through the aperture and an intensity measured by a photodetector of the reader.
