[Histonet] recycled alcohol versus reagent grade alcohol

[Roy, Ryan]

Hello Histonet,

How do other labs test and verify the percent grade of alcohols and what is the assumed percent grade of reagent alcohol? We use recycled alcohols but today based on not having reagent grade we used 97% tested recycled as our flush.

The reasoning behind this was that Reagent grade varies from 95%-greater than 100%. Is this true?

Thanks in advance,

Ryan
