We never had paraffin in the holding chamber. Until now there have no
negativ effects occurred.

Betreff: [Histonet] question of the day - embedding
Hi all question/dilemma of the day.
I have been of the view that the longer tissue sat in melted
paraffin the harder it got, especially animal tissue. So with that said,
for the past nearly 10 years I have not used melted paraffin in the
holding chamber of the embedding center. I just keep the chamber warm,
and work that way. Thus keeping the tissue from continuing to cook and
harden in the wax.
Everyone else I am currently working with has never seen the
method I use, and firmly believe that this causes harm to the tissues if
they are not in paraffin.
Thoughts ideas etc. I am dying to know if I am the only one that
worries about length of time that animal tissue sits in paraffin.
