Abstract
A device and method solves the problems of improving precision, in particular in reducing movement of a cuvette, particularly lateral or side to side movement of a cuvette, during the measurement process. The device, which stabilizes a cuvette during a measurement read in an analyzer having a cuvette path of travel, includes: a fixed support located on a first side of the path of travel and 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 and biased against a side of the cuvette at a location that does not interfere with the optical window on the cuvette on which the measurement read takes place, and which is opposite the side abutting the fixed support.
