ABSTRACT:
A method and device for calibrating or checking the calibration of vertical photometers. The invention may also provide easy and convenient assay results for diagnostic profiles. The invention comprises pre-dispensed amounts of a suitable reagent, chosen for the particular use, disposed in a vessel with an amount of a wetting agent to yield a reproducible meniscus in the resulting control solution. The control solution is dried to leave a precise amount of dried reagent and other constituents in the vessel which can then be stored and distributed until subsequent use. The dried control solution can then be reconstituted to provide a standard having known absorbance and physical characteristics.
