[Histonet] processing skin and intestines

[Gayle Callis]

Isn't the Citadel a carousel (sp?) style with vacuum on last station of 
paraffin?  I am not totally familiar with this processor.

With our VIP (vacuum/pressure throughout), 45 minutes per station of 
dehyrant, clearing and paraffin (60C) at most but we get superb exchange of 
solvents with VIP processing, and we never add heat to dehydration/clearing 
steps - dries out the tissue even more.

For rat, I would do 1 hour on VIP.   If you do not have vacuum and pressure 
throughout for each station,  then mouse tissue will survive 1 hour timing 
on a carousel style nicely.

Keep in mind animal are less fatty than human, and can easily be 
overdehydrated, dried out.
