I have one MD who sends me skin biopsies this way. He orients then so
that if I cut the very tip off and use a wooden applicatir to push the
OCT blob out, I can embed the  cone shape on the chuck and still maintain
proper orientation. It only takes a moment to thaw the OCT directly
against the mircrofuge tube, enough to loosen the OCT blob and still cold
enough around the tissue to prevent loss of orientation and subsequent
freeze-thaw artifact.
