being lazy and the Hoffmans generator

Post by kimm »

Being entirely lazy here - haven't used our hoffmans generator for a whole year and i can not remember the concentration of sulfuric acid that we used. :coffee: I really should get off my butt and look through my files but I really do not want to right now. Don't expect you guys to go looking for the information ........... just if you know off hand - I know it is here somewhere - ......
