[NHCOLL-L:4092] Re: Possible replacement to alcohol storage?

[Furth, David]

You might consider propylene glycol or propylene phenoxytol.  They are certainly less expensive than the Novec fluid and less problematic.

If anyone has any experience working with this fluid for the preservation of natural history specimens, would you mind posting it to the list?  We are looking for alternatives to ethyl alcohol as a storage medium for gallery specimens.
 
Thanks very much,
Brad

Is anyone familiar with this new alcohol storage replacement, and what it can do to the scientific utility of specimens vs. the materials we are more familiar with?  I understand it is being used at the Smithsonian and would interested to hear from anyone there involved, or if any testing has been done.

 

Thank you in advance, Chris Del Re

Calamari in Smithsonian's new Ocean Hall

Back in August, the area science writer's group got a sneak preview of the Smithsonian's new Sant Ocean Hall, which opened in September. The main reason was super-sized calamari - a 25-foot-long female specimen of a giant squid. This is calamari that would happily eat you - or another giant squid. Our expert said they tend to congregate in groups of about the same body size, which minimizes the threat of being eaten by one's neighbor.
The Smithsonian used a new technology developed by 3M to preserve it. The fluid, called Novec, was originally developed as an electronics-friendly fire suppressant. One representative said they had operated laptop computers that were completely immersed in the stuff; another said one researcher had tossed a cell phone into it and called himself.  

Post 911, Smithsonian realized that the total volume of alcohol used to preserve specimens in its collections had approximately the explosive power of a fully loaded  747. So, a non-volatile fluid that didn't bleach or stain tissue and didn't cloud up over time was of great interest.
