1. A cell for performing optical measurements in an automatic analyzer having a griping means for transporting the cell, which comprises:
- (a) a tubular body having (i) two opposite ends, (ii) two plane-parallel walls positioned parallel to each other and to the longitudinal axis of the cell, said walls extending between said two opposite ends, and (iii) a bottom wall having the shape of a half-cylinder of a preselected diameter, projecting away from the tubular body, the first opposite end being open and the second opposite end being closed by the bottom wall;
(b) each of the plane-parallel walls at the open end of the tubular body having a tongue which extends outwardly from the open end in a direction perpendicular to the plane-parallel wall and ending at an outer edge;
(c) each tongue having an upper surface and a recess;
(d) each tongue and its recess being positioned symmetrically relative to the other tongue and its recess with respect to the longitudinal axis of the cell; and
(e) said cell having a one piece molded construction of transparent plastic material, and being constructed and arranged such that the dimensions of each tongue and its corresponding recess are preselected to permit cooperation with a gripping means to releasably engage therewith.

Abstract
A cell for performing optical measurements in a automatic analyzer includes a cell having a tubular body. The body has two plane-parallel walls, and is open at one end and closed at the opposite end by a bottom wall. At the open end of the body, tongues extend perpendicularly outward from each plane-parallel wall. Each tongue includes a recess, with each tongue and its recess being symmetrically placed relative to another tongue and its recess with respect to the longitudinal axis of the cell.

11. A cell for performing optical measurements in an automatic analyzer having a gripping means for transporting the cell, which comprises:
-
(a) a tubular body having (i) two opposite ends, (ii) two plane-parallel walls positioned parallel to each other and to the longitudinal axis of the cell, said walls extending between said two opposite ends, (iii) two side walls extending between the plane-parallel walls, and (iv) a bottom wall having the shape of a half-cylinder of a preselected diameter, projecting away from the tubular body, the first opposite end being open and the second opposite end being closed by the bottom wall; (b) two tongues located adjacent to the tubular body and extending outwardly from the open end in a direction perpendicular to the plane-parallel walls and ending at an outer edge; (c) each tongue having an upper surface and a recess; (d) each tongue and its corresponding recess being positioned symmetrically relative to the other tongue and its recess with respect to the longitudinal axis of the cell; (e) each tongue having a zone situated between the recess and the outer edge of the tongue, the zone having a flat surface adjacent the outer edge, which forms a preselected angle with the plane perpendicular to the longitudinal axis of the cell; (f) the side walls having an upper and lower portion, and an elongated outer projection which extends between the upper portion of the side wall and a point adjacent to the bottom wall of the tubular body; (g) said cell having a one piece molded construction of transparent plastic material, and being constructed and arranged such that the dimensions of each tongue and its corresponding recess are preselected to permit cooperation with a gripping means to releasably engage therewith. - View Dependent Claims (12, 15, 16)
