Microscale Crystallization – Craig Tube For this experiment‚ we had to find the percent recovery and melting point of pure sulfanilamide from impure sulfanilamide using the crystallization technique. To start‚ .1004 grams of impure sulfanilamide was put into a Craig tube with enough ethyl alcohol to barely pass the top of the sulfanilamide. The Craig tube was put into a stone block until boil‚ then check to see if the solid material had dissolve. With the addition of two more drops from a supply of 2
