Self-stacking reagent slide
First Claim
1. A self stacking reagent slide comprising a substantially planar body, having a reaction area, said reaction area being defined by an opening through said planar body and adapted for engagement of a sheet-like porous medium, said planar body being further provided with interlocking means said interlocking means comprising ribs and mating grooves arranged along an axis parallel to the plane of said planar body so as to permit the sliding engagement and disengagement of the top face of said slide with the bottom face of a slide of like construction and the sliding engagement and disengagement of the bottom face of said slide with the top face of a slide of like construction.

17. In a reagent slide stack adapted for use in an automated clinical analyzer typically utilizing a dispensing cartridge, so as to enable the analyzer to sequentially remove an individual slide from said stack, the improvement comprising:
a stack of reagent slides suitable for use in an automated clinical analyzer independent of a dispensing cartridge, said stack comprising (i) a plurality of reagent slides, each such slide comprising a substantially planar body having a reaction area, said reaction area defined by an opening through said planar body and adapted for engagement of a sheet-like porous medium, and (ii) interlocking means associated with each such slide, said interlocking means comprising ribs and mating grooves arranged along an axis parallel to the plane of said planar body, thereby, enabling the organized stacking of the reagent slides on top of one another by mating engagement of the ribs and grooves on one slide with the ribs and grooves of an adjacent slide and the sequential removal of an individual slide from said stack by sliding disengagement of the interlocking means of said individual slide from the stack.
