a mistake-proofing feature formed in a first longitudinal end of the body and shaped such that the first longitudinal end is asymmetric with respect to the longitudinal axis, wherein the mistake-proofing feature is configured to:
allow cooperation of the cover member into a slot of a sample holder when the cover member is in a first orientation with respect to the sample holder, and
