Dear Dawn,

I cannot see the point of keeping spare disposable blades in the
cryochamber, as when they are placed into the blade holder they take less
than 30 secs. to reach sectioning temperature. Plus the fact as a pack of
blades are already very expensive, and to have this modified for cryowork
which would be very simple, would only give an excuse to charge more.

Best Regards
