Abstract: A processor assembly including: an exposure station operable to expose a sample on a slide; a print station operable to apply a reagent to the exposed sample through a thermal inkjet process; and a robotic transfer mechanism to transfer the slide from the exposure station to the print station. Also, a reagent cartridge including: a body defining a container having a volume therein; a nonmetallic bag in the container operable to contain a reagent; and a printhead at a base of the body, the printhead coupled to an outlet of the bag. Further, a method including exposing a sample on a slide in a processor assembly; robotically transferring the slide to a printing station of the processor assembly; and applying a reagent to the exposed sample at the printing station by a thermal inkjet printing process.

Abstract: A processor assembly including a core module operable to expose a sample on a slide; a staining module operable to apply a stain to the exposed sample; and a robotic transfer mechanism to transfer the slide from the core module to the staining module. Also, an apparatus including a rectangular body having an open rear end and an opposite front end; a flange having a first side and a second side, wherein the first side of the flange is coupled to the front end of the body; and a pair of legs extending from second side of the flange, wherein the pair of legs are operable to engage opposite side edges of a slide.
