Abstract
Abstract The photometric analyser comprises: a primary rack (1) to receive a plurality of test-tubes (2); a cross-table (3) designed to receive a micro-titre plate (4), arranged next to the primary rack (1) and capable of being positioned as desired in the x/y direction in the horizontal plane; a testpiece distributor arm (5) arranged over the primary rack (1) and cross-table (3) capable of being positioned as desired in the x/y direction in the horizontal plane; a photometer (6) located in the positioning region of the cross-table (3) the beam path (7) of which impinges at right angles to the x/y surface of the cross-table (3); and a programmable computer (8) for controlling the overall photometric analyser. The device is suitable in particular for the performance of enzymatic immunity tests.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
Photometric analyzer, in particular for performing enzyme immune tests, comprising the following elements: - a primary rack (1) for holding a variety of sample tubes (2); - a work table (3) located alongside the primary rack (1) which can be positioned in any x/y direction desired in a horizontal plane for supporting a microtitration plate (4); - a sample distribution arm (5) which is located above the primary rack (1) and the work table (3) and which can be positioned in any x/y direction in a horizontal plane; - a single photometer (6) firmly located in the positioning sector of the work table (3) whose beam path (7) vertically intersects the x/y plane of the work table (3); and a programmable computer (8) for controlling the entire photometric analyzer.
