Step1 - Take Milk Butyrometer of 10.75 ml
Step2 - Take 10 ml of sulphuric acid in the butyrometer from Tilt Mesure. (having a specific gravity of 1.807 to 1.812 g/ml at 27°C corresponding to a Concentration of sulphuric acid from 90-91 per cent by weight)
Step3 - Add 10.75 ml of milk from the average sample with Milk Pippet to the butyrometer.
Step4 - Add 1 ml of amyl alcohol through Tilt Measure of 1ml to the Milk Butyrometer
