Abstract:
A cuvette for measuring absorption of irradiation in liquid probes, comprising:a substantially rectangular body having an inner space for receiving a sample liquid probe and at least one pair of planar parallel windows spaced from each other and extending parallel to each other; andfour ribs provided on four corners of the body, respectively, and extending at least over a portion of a body height, an entire cross-section of the cuvette lying within imaginary limiting lines connecting end points of the four rib,wherein the inner space is formed in an essentially box-shaped upper part with an upper opening for filling and removing sample fluid, and in a smaller, essentially box-shaped lower part for the measuring volume connected with the upper part via a transition, wherein the cuvette has two pairs of planar-parallel windows provided in the lower part which lie opposite one another, wherein a distance of the windows of one pair is different from a distance of the windows of another pair in order to make available various layer thickness of the sample fluid for measurement of samples, and four feet flush with the corners of the upper part which extend away from the upper part at least up to the level of the floor of the lower part.
