A specimen processing system is capable of processing specimens carried on slides. The specimen processing system can sequentially deliver slides and opposables to specimen processing stations. The specimen processing stations can use the opposables to apply a series of liquids to the specimens. The applied liquid can be moved along the slide using capillary action while the specimen processing stations control the processing temperatures. The applied liquid can be in a fluid-carrying gap. The opposable can contact the slide to vary a cross section of the fluid-carrying gap.

1. A specimen-processing assembly, comprising: a platen configured to support a slide having a specimen-bearing surface; an opposable including— an arcuate body having a fluid-manipulating surface,a first spacer at a first side portion of the fluid-manipulating surface, anda second spacer at a second side portion of the fluid-manipulating surface, the second side portion being spaced apart from the first side portion, wherein the first and second side portions are generally parallel to the specimen-bearing surface; andan actuator configured to rotate the opposable relative to the platen, to rotate the platen relative to the opposable, or both in a path of rotation from a first end state at which a first portion of the first spacer and a first portion of the second spacer contact the specimen-bearing surface to a second end state at which a second portion of the first spacer and a second portion of the second spacer contact the specimen-bearing surface; wherein the first portion of the first spacer is spaced apart from the second portion of the first spacer at the first side portion of the fluid-manipulating surface; and the first portion of the second spacer is spaced apart from the second portion of the second spacer at the second side portion of the fluid-manipulating surface; andwherein the first spacer has a height profile parallel to the specimen-bearing surface different than a height profile of the second spacer parallel to the specimen-bearing surface; and wherein an average height of the first portion of the first spacer is greater than an average height of the first portion of the second spacer; and an average height of the second portion of the first spacer is less than an average height of the second portion of the second spacer. 2. A specimen-processing assembly, comprising: a platen configured to support a slide having a specimen-bearing surface; an opposable including— an arcuate body having a fluid-manipulating surface,a first spacer at a first side portion of the fluid-manipulating surface, anda second spacer at a second side portion of the fluid-manipulating surface, the second side portion being spaced apart from the first side portion; andan actuator configured to move the opposable relative to the platen, to move the platen relative to the opposable, or both in a path of rotation from a first end state to a second end state and through a range of intermediate states between the first and second end states, the first and second side portions being generally parallel to the specimen-bearing surface,wherein the first spacer has a height profile parallel to the specimen-bearing surface different than a height profile of the second spacer parallel to the specimen-bearing surface; the body is configured to form a fluid-carrying gap between a portion of a central region of the fluid-manipulating surface and a corresponding portion of a central region of the specimen-bearing surface; wherein rotating the opposable relative to the platen, rotating the platen relative to the opposable, or both changes the portion of the central region of the fluid-manipulating surface and the corresponding portion of the central region of the specimen-bearing surface forming the fluid-carrying gap; the first and second spacers are configured to cause a cross section of the fluid-carrying gap in a first plane perpendicular to the specimen-bearing surface to have a first asymmetry at the first end state relative to a bisecting plane parallel to the specimen-bearing surface, and to cause a cross section of the fluid-carrying gap in a second plane perpendicular to the specimen-bearing surface to have a second asymmetry relative to the bisecting plane at the second end state; and the first asymmetry is different than the second asymmetry. 3. The specimen-processing assembly of claim 2, wherein: the first spacer includes a first plurality of discrete protrusions configured to contact the specimen-bearing surface; andthe second spacer includes a second plurality of discrete protrusions configured to contact the specimen-bearing surface. 4. The specimen-processing assembly of claim 2, wherein the first and second spacers are configured to cause at least a portion of the fluid-manipulating surface to perpendicularly rotate relative to the path of rotation while the actuator rotates the opposable relative to the platen, rotates the platen relative to the opposable, or both in the path of rotation. 5. The specimen-processing assembly of claim 2, wherein: the first and second spacers are configured—to cause at least a portion of the fluid-manipulating surface to rotate in a first direction while the actuator rotates the opposable relative to the platen, rotates the platen relative to the opposable, or both in a second direction, and to cause at least a portion of the fluid-manipulating surface to rotate in a third direction while the actuator rotates the opposable relative to the platen, rotates the platen relative to the opposable, or both in a fourth direction; the first, second, third, and fourth directions are different; the first direction is generally opposite to the third direction; and the second direction is generally opposite to the fourth direction. 6. The specimen-processing assembly of claim 2, wherein a section of the height profile of the first spacer and a section of the height profile of the second spacer on opposite sides of the opposable are different. 7. The specimen-processing assembly of claim 2, wherein the actuator is configured to rotate the opposable such that a volume of liquid held between the fluid-manipulating surface and the slide, is translated along the slide. 8. The specimen-processing assembly of claim 1, wherein an average height of the first and second portions together of the first spacer is about equal to an average height of the first and second portions together of the second spacer. 9. The specimen-processing assembly of claim 1, wherein: a radius of curvature of the fluid-manipulating surface in a bisecting plane parallel to the path of rotation is from about 2 inches to about 30 inches; the average height of the first portion of the first spacer and the average height of the second portion of the second spacer individually are from about 0.004 inch to about 0.008 inch; and the average height of the second portion of the first spacer and the average height of the first portion of the second spacer individually are from about 0.001 inch to about 0.004 inch. 10. The specimen-processing assembly of claim 1, wherein an average height of a third portion of the first spacer between the first and second portions of the first spacer is about equal to an average height of a third portion of the second spacer between the first and second portions of the second spacer.
