Abstract
A stack of plastic articles and a process of forming the stack are disclosed. Preferably the stack is of heat-fusible plastic slide elements for use in a diagnostic analyzer, the elements being temporarily and non-destructively fused together so that the stack can be used free of a cartridge. In another embodiment, the stack can be of any plastic article temporarily fused to adjacent elements, one side edge of each element bearing a colorant and another bearing no colorant, so that a bar code for the stack is inherently formed simply by rotating each element to project outwardly the colored side edge or the side edge lacking colorant, prior to fusing the elements together.
