<p>Dear Bo,<br>

</p>
<p>Indeed, as long the glycerol concentration is at or above 65% and the humidity in your facility is kept below 70% mould cannot grow.</p>
<p><br>
</p>
<p>When will the new exiibit be ready? Would definitely pay a visit to see the result.</p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Thank you all for detailed and interesting information on this topic. Glycerol seems to be very interesting making nice specimens for exhibitions if you have fresh specimens with nice color. I will
try it in the future for some small richly coloured fish. Is it correct that if you keep the concentration at 65% you don’t run in to problems with mould?
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="color:#1F497D">Regarding our squid(s) they aren’t that nice and if we can’t continue with ethanol I think we transfer selected specimen to a formalin solution after all (Jon, thank you
for the publication with relevant references). James, I will check if we have any pictures and size estimates. The length of the mantel is about 1 m for both specimens. Ironically, the one we had for display is the one in worst condition (in several pieces,
semi rotten I would say) collected close to Scotland around 1990 or so. The other one was collected by a shrimp trawler from Sweden in 1960 and this specimen have commonly been referred to as “the green squid” . Initially it was stored in a tank made of cupper.
Nevertheless it’s in much better physical condition and consequently we will continue having a giant squid on display but not the same specimen.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><a name="_GoBack"></a><span lang="EN-US">Dear all,<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><span lang="EN-US">Up to recently we had a giant squid
<i>Architeuthis </i>sp<i>. </i>in exhibition (“Liv in Vatten” = Life in Water/Aquatic life). It was contained in an aquarium, 80% ethanol (650 liters!). For the moment, we are planning for thorough modernization, i.e. the exhibition will be rebuilt from scratch
but we wish to keep the squid. It is very popular. However, we might face problems regarding fire safety regulations and one idea that came up was to transfer the specimen to weak formalin solution (1%).
<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><span lang="EN-US">-Anyone having any experience and perhaps suggestions regarding concentration and suitable buffer?<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:10.0pt;line-height:115%"><span lang="EN-US">My limited experience is based on museum specimens (mainly fishes) that previously were in the old NRM exhibitions. I come across them now and then in the scientific collection
and according to older documents, the ethanol was replaced with formalin around 1960 because the expense. Anyway, this old exhibition jars with specimens look very nice (except for bleaching of specimens) and the fluid (formalin solution) looks like clear
water. <o:p></o:p></span></p>
