Abstract

Apparatus and method for preparing a smear of a biological fluid substance on a substrate, utilizing a ribbon having relatively small openings in at least one surface thereof which openings are of substantially uniform size and are arranged substantially uniformly both longitudinally and transversely of the ribbon throughout at least a portion of the ribbon. The method includes the steps of supporting the substrate for movement and supporting the ribbon by a support to close proximity to the substrate at a substance-applying station, for a run of the ribbon past a portion of the substrate. Further steps include introducing a relatively small quantity of the aforementioned substance between the aforementioned ribbon surface portion and the substrate at the substance-applying station to spread by capillarity in a direction transversely of the ribbon, and moving the substrate in a direction to smear the substance on the substrate.
