Formalin types


Hello all!
I thought I had sent this message yesterday but it did not go through!
Here is my question/problem:
The histology lab and the surgical suites use NBF.  Surgical pathology
(where the tissue is grossed) uses sodium acetate formalin. Consequently,
some tissue gets completely fixed in NBF while in transit to surgical
pathology (or sitting overnight) while other tissues get completely fixed in
sodium acetate formalin (recieved fresh to surgical pathology).  
Here is my question(s).
What effect does it have on tissue to be transfered from one type of
buffered formalin to another?
Does anyone have any resources for sodium acetate formalin or have
compelling reason why we should not be using it?  I can only find one
reference with mention of sodium acetate formalin (Luna)

Thanks for any info/suggestions/help!!
