<div class="moz-cite-prefix">Dear Tonya,</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">adding to Andy and John and picking up
what Doug said, there are two main points to consider:</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Firstly, as John mentioned, the
(plastic) stoppers fail, which often means that they start to melt
down or release chemicals (e.g. softeners), which, because of
small volumes inside tubes, might trigger secondary reactions that
can harm contained material rapidly (e.g. rubber-based stoppers
melting into vials and specimens, softeners changing chemical
equilibria, etc. ). Because jars are packed with tubes, it is
difficult to monitor this, because usually you only look to the
outer vials, but rarely those in the middle of the jar (unless you
would remove all smaller jars inside the jar, which nobody does, I
assume).</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Secondly, it might be worth taking the
glass tubes themselves in consideration as well. Soda-lime glass
tends to release alkaline ions, which can create very reactive
surface layers on the glass surfaces inside these tubes. While
this is not so much of a problem for larger specimens as fish, the
contact surface of small invertebrates with containers walls is
much larger. Our Entomology here in Munich therefore relies on
borosilicate tubes. There are various producers for such
borosilicate test tubes.<br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">This basically matches the
conservational recommendations of the KUR-Project of colleagues in
Berlin for the restoration of their fluid collections (only in
German, here is a DeepL-translation of the relevant section):</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Store smaller preparations in
borosilicate tubes with cotton wool stoppers (KERMA company) (for
spiked preparations<br>
(for spiked specimens wrap stopper with Japanese paper from PAPER
NAO) to prevent contact with highly reactive<br>
soda lime glass weathering layer,<br>
- Minimum volume for collection jars 200 ml as safety against
desiccation.</div>
<div class="moz-cite-prefix"><br>

<div class="moz-cite-prefix">Hope this help</div>

second Andy's recommendation of the polyester fiber plugs.
They are far easier to work with and rarely come out of the
vials if inserted correctly. Compressible stoppers, soft
flexible lids, and rigid lids will all fail over time.</div>

<p class="MsoNormal">Here at KU, out entomology division
is doing similar by placing vials into larger jars for
more efficient storage. However, instead of using caps,
they are using polyester batting to stopper each vial
which has the advantage of allowing alcohol exchange
between each individual vial and the surrounding alcohol
in the jar. A small wad of the batting inserted into
the top of the vial provides a good barrier -

Hello all,<br>
<br>
We are planning on rehousing our collection of
vertebrate parasites in ETOH (a range of
invertebrate taxa) before we move to our new
building in a few years. The goal is to: a) make the
specimens safer from accidental dehydration; and b)
save space and alcohol volume. The collection is
currently housed in McCartney vials. They are good
but do eventually fail, and dry out rapidly when
they do. In addition, there are many specimens that
could be housed in much smaller containers, which
would save lots of space, if it were appropriate to
do so.<br>
<br>
Our plan is to move specimens and labels into
smaller vials, filled with alcohol, and then to
place those smaller vials into 2L jars topped with
ETOH. Jars would be organised taxonomically and with
a large label inside the jar so specimens will still
be easy to find (though it will probably be annoying
to have to go through the whole jar but hey ho). But
we think this solution offers greater storage/space
potential and should allow us so safely preserve
smaller specimens in smaller vials, without the risk
of dehydration. <br>
<br>
My question regards vial tops. Right now we are
planning on using LDPE push top lids (into soda
glass vials). I think this should be fine, but I
just wanted to collect the collective mind to see if
anyone had any thoughts on this to offer? It's the
lids that I am wondering about. The only alternative
I can think of is to use cotton stoppers instead,
but I worry that cotton is too 'catchy' for
invertebrates and might lead to damage. We could get
screw top lids, but they are wadded and I am not
sure what the lid material is (but it is black so
maybe Bakelite?).<br>
<br>
The specimens will be housed in a climate-controlled
vault at 18C and 50% rH, so I think there shouldn't
be any issues of lids popping out because of
temperature changes, etc (though that thought does
make me feel nervous I admit).<br>
<br>
Thanks in advance and apologies for the very long
email!<br>
<br>
Cheers,<br>
<br>
Tonya<br>
