Re: [Histonet] Modified Davidson solution

[John Kiernan via Histonet]

The Davidson/Hartmann fixative is just another alcoholic formaldehyde mixture 
acidified with acetic acid. Like all others of that ilk it was intended for 
making up in the lab soon before using. Storage causes slow deterioration. The 
ethanol slowly gets esterified by the acetic acid, making ethyl acetate, which 
has no fixative properties. This change is evident from the fruity smell of the 
ester, which becomes evident after a week or two. All this has been in the 
textbooks for more than 50 years.
Why doesn't every lab spend perhaps $200 on a couple of books?  For obvious 
reasons I recommend my 5th edition (ISBN 9781907904325; $82.50,from the 
publisher, which is $30 less than Amazon's price), but there are other 
histotechnology books that are very good.  A book may cost much less than a big 
bottle of a deteriorating mixture of questionable value, and you and your staff 
could learn a lot by reading.
