Dear Tony,

Yes, sectioning fat is not a problem with our cryostats, to back up my words
I have just sectioned a piece of pig fat 20 x 15mm including the skin @ 5
microns on our model OTF/AS/LT, chamber, microtome, knife, anti-roll plate &
specimen all at minus 38 degs.C. without problems, I even let one of our
electrical engineers who has never sectioned on a cryostat, cut a ribbon of
6 sections @ 5 microns, he had no problems and all the sections were good.

There are many of our cryostats in the Sydney area, if you would like me to
get some information on their location, I would be pleased to do so.

Best Regards

Can you really cut frozen sections of fat? I'm impressed!!!!!
