摘要： A cuvette holder is provided to allow a flow cell optical analyzer to be adapted for coagulation analysis. The flow cell analyzer has a light source and a photo detector defining a first and a second end of an optical path, a vacuum source for drawing a liquid sample through a flow cell positioned in the optical path so that light from the light source passes through the sample, and means for analyzing data collected at the photo detector. The coagulation analyzer has a light source and a photo detector defining the respective ends of an optical path, a cuvette containing a liquid sample positioned in the optical path for passage of light from the light source through the liquid sample, a means for agitating the liquid sample and a means for analyzing data collected at the photo detector. The adaptation is achieved by removing the flow cell and replacing the flow cell with a cuvette holder comprising an opening for receiving and holding the cuvette in the light path and communicating the vacuum source to the cuvette holder, the means for agitating provided by a magnetic stirring bar in the cuvette, the stirring bar being magnetically coupled to a rotor rotatably mounted in a rotor housing below the cuvette and having a permanent magnet mounted on a top surface thereof, wherein the rotor is rotated in the rotor housing by an air pressure differential in the rotor housing created by the communication of the vacuum source to the cuvette holder.
