[Histonet] disposable blade holder and blades for A.O. Spencer 820 Microtome

From:Kevin Cannariato

First off, forgive me for asking what is probably a novice question.

I am a geologist that would like to sample tree rings at sub-annual 
resolution. This requires taking ~20 um thick slices of tree cores. 
People who have done this before use a microtome. I have obtained an 
American Optical Spencer 820 microtome that appears to be in working 
order. We have been told that it would probably be easier to use 
disposable blades rather than the old one that came with it.

I would like to know where we could purchase a disposable blade holder 
and disposable blades for this American Optical Spencer 820 microtome.
