Butyrometer

 

an instrument for measuring the fat content of milk. The most widespread butyrometer is a glass cylindrical vessel with a scale which indicates the fat content of milk; the value of one division on the scale is 0.1 percent (by weight). To use such a butyrometer, one pours 11 cu cm (cc) of milk, 10 cc of sulfuric acid, and 1 cc of amyl alcohol into the butyrometer. The vessel is then stoppered and shaken; the components of the milk, except for the fat, dissolve. In order to obtain a better separation of the fat, the butyrometer is placed in a centrifuge, and the quantity (in percent) of fat in the milk is determined after centrifuging.

The fat content was read directly on the butyrometer and an average value of the two determinations was calculated.
Then the butyrometer was capped with rubber cap and was shaked vigorously until all particles were melted.
