<div>Dear Mandy,<br>
</div>
<div><br>
</div>
<div>Another simplification: If you skip drawing the line and dip a tiny piece of the paper in the fluid, it will immediately sink in ethanol and keep floating for quite some time in formalin. It saves ink and also prevent the ink of the marker bleeding into
your ethanol solution.</div>
<div><br>
</div>
<div>By the way, if you want to add a handwritten (with Indian ink) or printed label to aqueous preservation fluids like formalin and make sure that it sinks to the bottom of the jar quickly and stays there, first dip it in ethanol and then place it in the
formalin.<br>
</div>

<div>Kind regards,</div>

<p class="MsoNormal"><span style="font-size:10.0pt; font-family:"Arial",sans-serif">Thank you to all the people who responded regarding testing for formalin when you are unsure whether a specimen is stored in ethanol or formalin (particularly problematic in
historic museum specimens). I had an excellent idea sent to me by colleagues from NIWA (<span style="color:black; background:white">The National Institute of Water and Atmospheric Research in Wellington, New Zealand) that I would like to share. It is very
simple, very inexpensive and it is very effective.</span></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt; font-family:"Arial",sans-serif" lang="EN-NZ">Simply draw a line of permanent marker on a strip of wet label paper. Dipped into a formalin solution, the marker stays intact. Dipped into an into an ethanol solution
the marker starts running, or bleeding into the paper. </span></p>
