An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates “on demand” for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.
