ABSTRACT:
A large diameter ball is placed within the sample cavity of a liquified petroleum gas sample vessel or cell. After the sample has been taken, the entire cell may be shaken to cause the ball to break up stratification, and to mix the sample. When a vessel or cell is emptied, a ball fits within hemispherical cavities between a piston and an end. The large diameters of the ball and cavities result in shoulders or ledges, which are less than half the diameter of the ball, so that they do not prohibit the movement of the piston because the ball will be forced into the cavities regardless of the orientation of the cell.
