[Histonet] Histology Grade Solvents

[Rene J Buesa]

Some manufacturers qualify a solvent that is NOT chemically pure (not good for chemical quantitative analytical purposes) BUT "pure enough" to be used in histology, specially for processing or staining.
  I have always taken exception to this "histology grade" issue because it is somewhat demeaning, as if what we do do not deserve a good quality reagent grade chemical. Those are the standard to prepare our stock staining solutions that should be as pure as possible, especially when silver staining is involved.
  So, "histology grade" reagent is one that we can use, but that a chemist "should not".

  Good Friday Morning to everyone.-YEAHHH!! It's been one of those weeks:(

I was asked by someone about this and not sure what the answer is.

"I have a quick question for you regarding histology grade solvents. Many
companies use this as a grade but is there an official specification for
this grade? If so, could you direct me to the document."

Any ideas??

Thanks

Mark
