<div class="moz-cite-prefix">rising and staging times depends on the size of the specimens and how readily superfluous the formaldehydes is diluted from them. The specimens shown may require 2-3 days of rinsing, and then slowly going up 20/40/60/70. Each of
these steps may take 1 week or longer, it depends how much formaldehyde comes out of them.</div>

<div class="moz-cite-prefix">All together you should assume at least a month, but it can take you longer.</div>

<p class="MsoNormal"><span lang="NO-BOK">Dear all,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="NO-BOK"><o:p> </o:p></span></p>
<p class="MsoNormal">Recently, I have discovered that most of our larger specimens kept in the large collection jars, are kept in formalin (photo for reference).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have looked into removing the specimens from formalin and placing them into ethanol. I understand the steps that have to be taken, but I was wondering if anyone has advice on the soaking time for each step. That is the only thing that
is kept vague in the texts that I have read. One reference mentioned that tortoises and racoons take two to three days.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Most the specimens that I will work with a large fish, cephlapods, and birds.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In case any of you have done this, any advice on this or the process is appreciated!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am also open to having a quick chat via Teams or Zoom. <o:p>
