[Nhcoll-l] Phenoxyethanol

[Dirk Neumann]

Dear Tonya,

several recipes exist and have been used in collections since the mid 
1950ies, mainly for marine invertebrates, but no only. Simon Moore 
published 
<https://www.natsca.org/sites/default/files/publications/books/Fluid%20Preservation.pdf> 
on it back in 1999 and colleagues from the NHM in London may chip-in.

John Simmons also has a own section on phenoxetol in his Fluid 
Preservation book 
<https://rowman.com/ISBN/9781442229662/Fluid-Preservation-A-Comprehensive-Reference> 
(pages 69-70)

The recommendation we give in our forthcoming book is that specimens 
from phenoxetol should first be re-fixed in a 4% formaldehyde solution 
for few days (depending on specimen size, body mass etc.) and then 
stepped up from 30-50-70% EtOH. This seems to have worked fine, but this 
experience so far refers exclusively to elasmobranchs, which tend to 
behave slightly different to fixatives and preservatives compared to, 
for example, bony fish (likely because of the cartilage). Close 
monitoring during stepping specimens up surely is advised.


Hope this helps
Dirk
