Wendy,
I think that in three days the tissue and the embedding medium will begin to
dehydrate. Instrumedics Protective Oil is designed to coat the block without
melting the surface of the block and will prevent dehydration. Please visit
our web site for the details www.instrumedics.com
If you have any questions please contact me.
