Patent ID: 8313713

Claim:
An analyzer for analyzing a sample comprising: a cuvette supply; one or more cuvettes, wherein the cuvettes each comprise a cantilever; a sample supply; a metering station for metering sample from the sample supply into the cuvette; an optical measurement station having a light source and detector for taking an optical measurement read of the sample, wherein the path of the light source and detector forms a measurement window; a cuvette conveyor for conveying cuvettes from the cuvette supply to the metering station and to the optical measurement station, wherein the cuvettes are mounted in the conveyor by cantilevering them; and a device for stabilizing a cuvette during a measurement read in the analyzer having a cuvette path of travel, comprising: a fixed support located on a first side of the path of travel having a first roller being located on the fixed support and directly abutting a side of the cuvette at a location that does not interfere with an optical window on the cuvette on which the measurement read takes place; and a movable support located on a second side of the path of travel having a second roller directly abutting a side of the cuvette being located directly opposite the first roller on the movable support at the location that does not interfere with the measurement read and wherein the centerline of the measurement window passes through the centerline of the first and the second rollers, wherein said device is located in the optical measurement station, and wherein the light source is located on the first or second side of the path of travel and the detector is located the other side of the path of travel.
