Abstract: A reagent substrate may include a reagent sample deposition area on which a sample of a reagent is deposited, and a number of diagnostic regions on which a diagnostic sample of the reagent is deposited for verification of deposition of the diagnostic sample. A reagent dispensing system may include a conveyor surface to convey a number of substrates, at least one reagent module located in-line with respect to the conveyor surface where the reagent module includes at least one reagent dispensing device to dispense a reagent on the substrates, and at least one optical sensor to verify the dispensing of the reagent at a number of diagnostic regions of the substrate.

Abstract: A reagent dispensing system may, in an example, include a processing device, a memory device coupled to the processing device, and a plurality of swappable reagent dispensing cartridges wherein a first set of the swappable reagent dispensing cartridges are maintained within a storage device off-line from a second set of swappable reagent dispensing cartridges maintained in-line.
