This is a distillation of our work this past year on working with insect
and invertebrate specimens in hand sanitizer, this technique is based on

In sum: </font><font size=2 face="Arial"> <br>
</font><font size=2 face="sans-serif"><br>
You can display and look at under the microscope insect specimens by putting
them in a hand sanitizer filled cuvette. Great for showing the public
insect specimens and letting them handle the specimens safely and also
good for certain types of microscopic work.</font><font size=2 face="Arial">

What is a cuvette?... Here is what Wikipedia says</font><font size=2 face="Arial">
<br>
<br>
A <b>cuvette</b> is a small tube of circular or square cross section, sealed
at one end, made of </font><a href=http://en.wikipedia.org/wiki/Plastic><font size=2 color=blue face="Arial"><u>plastic</u></font></a><font size=2 face="Arial">,
</font><a href=http://en.wikipedia.org/wiki/Glass><font size=2 color=blue face="Arial"><u>glass</u></font></a><font size=2 face="Arial">,
or </font><a href=http://en.wikipedia.org/wiki/Fused_quartz><font size=2 color=blue face="Arial"><u>fused
quartz</u></font></a><font size=2 face="Arial"> (for </font><a href=http://en.wikipedia.org/wiki/Ultraviolet><font size=2 color=blue face="Arial"><u>UV
light</u></font></a><font size=2 face="Arial">) and designed to hold samples
for </font><a href=http://en.wikipedia.org/wiki/Spectroscopy><font size=2 color=blue face="Arial"><u>spectroscopic</u></font></a><font size=2 face="Arial">
experiments. The best cuvettes are as clear as possible, without impurities
that might affect a spectroscopic reading. Like a </font><a href=http://en.wikipedia.org/wiki/Test_tube><font size=2 color=blue face="Arial"><u>test
tube</u></font></a><font size=2 face="Arial">, a cuvette may be open to
the atmosphere on top or have a cap to seal it shut. </font><a href=http://en.wikipedia.org/wiki/Parafilm><font size=2 color=blue face="Arial"><u>Parafilm</u></font></a><font size=2 face="Arial">
can also be used to seal it. </font>
<p><font size=2 face="Arial">Inexpensive cuvettes are round and look similar
to test tubes. Disposable plastic cuvettes are often used in fast spectroscopic
assays, where speed is more important than high </font><a href=http://en.wikipedia.org/wiki/Accuracy><font size=2 color=blue face="Arial"><u>accuracy</u></font></a><font size=2 face="Arial">.
</font>
<p><font size=2 face="Arial">Some cuvettes will be clear only on opposite
sides, so that they pass a single beam of light through that pair of sides;
often the unclear sides have ridges or are rough to allow easy handling.
Cuvettes to be used in </font><a href=http://en.wikipedia.org/wiki/Fluorescence_spectroscopy><font size=2 color=blue face="Arial"><u>fluorescence
spectroscopy</u></font></a><a href="http://en.wikipedia.org/wiki/Cuvette#cite_note-0"><font size=2 color=blue face="Arial"><u><sup>[1]</sup></u></font></a><font size=2 face="Arial">
must be clear on all four sides because fluorescence is measured at a right-angle
to the beam path to limit contributions from beam itself. Some cuvettes,
known as tandem cuvettes, have a glass barrier that extends 2/3 up inside,
so that measurements can be taken with two </font><a href=http://en.wikipedia.org/wiki/Solution><font size=2 color=blue face="Arial"><u>solutions</u></font></a><font size=2 face="Arial">
separated, and again when they are mixed. Typically, cuvettes are 1 cm
(0.39 in) across, to allow for easy calculations of </font><a href=http://en.wikipedia.org/wiki/Attenuation_coefficient><font size=2 color=blue face="Arial"><u>coefficients
of absorption</u></font></a><font size=2 face="Arial">. </font>
<p><font size=2 face="Arial">The technique is useful for very small specimen
inspections under the scope and for displaying larger specimens.

I taste a liquor never brewed,<br>
>From tankards scooped in pearl;<br>
Not all the vats upon the Rhine<br>
Yield such an alcohol!<br>
<br>
Inebriate of air am I,<br>
And debauchee of dew,<br>
Reeling, through endless summer days,<br>
>From inns of molten blue.<br>
<br>
When landlords turn the drunken bee<br>
Out of the foxglove's door,<br>
When butterflies renounce their drams,<br>
I shall but drink the more!<br>
<br>
Till seraphs swing their snowy hats,<br>
And saints to windows run,<br>
To see the little tippler<br>
Leaning against the sun!<br>
