<div class="moz-cite-prefix">Hi Bo,</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">maybe a comment pointing into a
slightly different direction (similar to what colleagues did in
Berlin), as you mentioned you are planning for a major renovation
of your exhibitions:</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">An alternative would be to have a
cabinet that is "inaccessible" for visitors and equipped with
necessary installations to comply with fire-safety regulations
(like a tank in an public aquarium). Thus the specimen would be
visible for the visitors, the container as such however would not
be part of the publicly accessible visitor space. This could help
to avoid transferring the specimen into a different fluid,
potentially causing secondary conservation problems.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">At the MfN in Berlin they used this
alternative to make the fluid collections accessible and
discoverable for visitors, while keeping the visitor and
collection space simultaneously strictly separated. They also used
this concept for a huge glass cabinet that shows a large diversity
of collection objects on display, including fluid-preserved
specimens.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Maybe worth a thought ...</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">With best wishes</div>
<div class="moz-cite-prefix">Dirk<br>

<p class="MsoNormal"><span style="color:#1F497D" lang="EN-US">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?

<p class="MsoNormal" style="text-align:justify"><span
style="color:#1F497D" lang="EN-US">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>

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%).

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>
