    • A disposable flexible disc radial cuvette array has its cuvettes divided into inner compartments and outer compartments by a ramp-shaped wall. These cuvettes are separated from their adjacent cuvettes by dual side walls and have uniform parameters. The annular cuvette array includes an integral opaque horizontal annulus having a first radial series of slots thereon, substantially aligned with the radial centers of the outer ends of the cuvettes, and has a second radially spaced set of slots generally aligned with the side walls. The cuvette walls and array hub portion provide rigidity. The annulus also has an inwardly extending flange covering the outer radial ends of the cuvette, there being formed therein slots open to both the inner and outer compartments. Locating projections extend upwardly from the disc surface in an embodiment adapted to position a rotatable, cuvette numbering, annular ring, the ring being variably, rotatably positionable to provide selectivity of the cuvette numbers. The thickness of the plastic material forming the array is selected empirically for proper optical and strength characteristics. The array is flexible and integrally spring biased between hub and annulus to maintain the bottom walls of the cuvettes against the rotatable support with which the cuvette array is to be utilized under pressure to maximize contact therebetween. The annulus is fusion bonded to the hub and cuvette chamber portion to form the integral array.
    • 一次性软盘径向比色杯阵列,其比色皿通过斜坡形壁分成内隔室和外隔室。 这些比色皿通过双侧壁与其相邻的比色皿分离并具有均匀的参数。 环形比色皿阵列包括整体不透明的水平环形空间,其上具有与试管的外端的径向中心基本上对准的第一径向系列的狭槽,并且具有与侧壁大致对准的第二径向间隔开的一组槽。 试管壁和阵列轮毂部分提供刚性。 所述环也具有覆盖所述试管的外径向端部的向内延伸的凸缘,其中形成有通向所述内隔室和外隔室的槽。 在适于定位可旋转的比色皿编号的环形环的实施例中,定位突起从盘表面向上延伸,该环可变地可旋转定位,以提供比色皿编号的选择性。 根据经验选择形成阵列的塑料材料的厚度,以获得适当的光学和强度特性。 阵列是柔性的,并且在毂和环之间一体地弹簧偏置,以将反应杯的底壁保持在可旋转的支撑件上,使得反应杯阵列在压力下被使用以使其间的接触最大化。 环形部分被熔合到轮毂和反应杯室部分以形成整体阵列。
