I gotta put in my defense of viscometers here -- ASSUMING you wash your biodiesel well (thus removing all soaps, methanol, free glycerine, lye, etc.), the only thing that will be left is biodiesel, mono- and diglycerides, and unconverted oil. All but biodiesel have much higher viscosities than biodiesel. I consider it a rather precise indicator of the degree of conversion in my own system, using a falling ball viscometer that cost around $150 as I recall... -K ------------------------ Yahoo!
