[Histonet] Re: Histology Grade Solvents

[Robert Richmond]

In chemistry, it's a good practice never to buy more purity than you
need. Look at common chemicals in the Sigma catalog - there can be
dozens of grades of a chemical for different purposes.

But Mark Elliott's original question hasn't been answered -

"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."
