Explain Methodology Required for Osazone Test?

Take about 250-300 mg of phenylhydrazine mixture in the 3 clean labelled 15 ml dry test tubes. Add 5 ml of the glucose, fructose and galactose solution to each, separately.  Shake and mix the contents of each tube and heat in a boiling water bath (water in the water bath should be boiling vigorously when you put the tubes and should continue to do so till the tubes are removed) for 30- 45 minutes. Remove the tubes from the water bath and put them in a test tube rack. Allow the tubes to cool slowly (not under the tap).

Take  slides, label them as Glu, Gal, Fru, Mal, lac, Suc and with the help of a dropper take out a drop of the yellow precipitate like crystals from each tube and put it on the respective slide. Examine the crystals on each slide microscopically.
