1. An apparatus for automatically processing microscope slides carrying specimens, the apparatus comprising:
- a drying station including a slide dryer, wherein the drying station is configured to automatically hold the microscope slides at an angle of inclination to promote draining of liquid from the microscope slides, and wherein the slide dryer heats the microscope slides held at the angle of inclination such that a temperature along each of the microscope slides is higher than about 50 degrees Celsius to at least partially dry the specimens carried by the microscope slides;
a staining station that automatically delivers stains onto the microscope slides to stain the at least partially dried specimens;
a cover-slipping station that automatically places coverslips on the microscope slides;
a transport device that automatically transports the microscope slides between the drying station, the staining station, and the cover-slipping station; and
at least one controller programmed tocommand the transport device to transport the microscope slides, which carry transfer liquid and the specimens, to the drying station,command the drying station to position the microscope slides at the angle of inclination to drain the transfer liquid from the microscope slides, andcommand the transport device to transport the microscope slides that have been dried in the drying station to the staining station.

Abstract
A slide processing apparatus controls the temperature and orientation of a microscope slide carrying one or more specimens. The apparatus heats the specimen-bearing microscope slide while the slide is oriented to both facilitate adhesion between the specimens and the slide and control movement of the specimens relative to the microscope slide. A slide dryer of the apparatus conductively heats the specimens using a conductive slide heater that physically engages the microscope slide.

9. An apparatus for automatically processing microscope slides carrying specimens, the apparatus comprising:
-
a drying station that automatically (1) holds the microscope slides at a substantially vertical orientation, and (2) heats the microscope slides held at the substantially vertical orientation to a temperature higher than about 50 degrees Celsius; a processing station configured to automatically dispense one or more fluids to contact the specimens carried by the microscope slides; a transport device configured to automatically transport the microscope slides between the drying station and the processing station; and a controller programmed to cause the transport device to transport the microscope slides carrying transfer liquid and the specimens to the drying station, and cause the drying station to position the microscope slides at the substantially vertical orientation to promote draining of the transfer liquid from the microscope slides. - View Dependent Claims (10, 11, 12, 13, 14)

15. An apparatus for processing microscope slides carrying specimens, the apparatus comprising:
-
a drying station that robotically positions the microscope slides at an inclined position, wherein the drying station automatically heats the microscope slides held at the inclined position such that a temperature along each of the microscope slides is higher than about 50 degrees Celsius to at least partially dry the specimens carried by the microscope slides; a staining station configured to automatically stain the at least partially dried specimens; a transport device configured to robotically transport the microscope slides between the drying station and the staining station; and one or more controllers programmed to command the transport device to move the microscope slides carrying transfer liquid and the specimens to the drying station, and command the drying station to position the microscope slides at the inclined position to promote draining of the transfer liquid from the microscope slides. - View Dependent Claims (16, 17, 18, 19, 20)
