Abstract
A cell for performing optical measurements in an automatic analyzer is molded in one piece from a transparent plastic material, and has a tubular body including two plane walls parallel to each other, two opposite ends, and a bottom wall. The first end of the tubular body is open and the second end is closed by the bottom wall which has the shape of a half-cylinder. The tubular body of the cell has two side-walls which extend between the plane-parallel walls and which each have an upper portion and a lower portion. The lower portion of each side wall is adjacent the bottom wall and includes an elongated, leg-shaped outer projection which extends along the longitudinal axis of the cell between the upper portion of the side-wall and a point at a certain distance from the bottom wall. Each of the plane-parallel walls has a tongue member adjacent the open end of the tubular body. The tongue members extend outwardly from the border of the open end of the tubular body of the cell in a direction perpendicular to the plane-parallel wall and ends at an outer edge. Each tongue member has an upper surface and a recess, and said tongues and their recesses are positioned symmetrically to each o…
