[Histonet] tissue slicer

[Philip Oshel]

Bad vibes, man.

But, Geoff, your device would work, but as you note, not for less 
than 1000 micron slices, definitely not 30 - 300 micron, and there'd 
be more tissue damage from compression. A vibratome is pretty much 
the only choice, there is no "all slices at once" instrument that 
I've seen.
