Hi Ryan,

Reagent grade alcohol can be purchased in different percentages such as 50% to 100%, etc.  It depends on what you purchase.    Reagent alcohol is simply a blend of three different alcohols, ethanol, methanol, and isopropyl and is created using a formula that is stated by the federal government to make it poisonous for human consumption.  

Recycled alcohol never comes back as 100%, and does vary from 95% to about 98%.

Subject: [Histonet] recycled alcohol versus reagent grade alcohol

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
