Figure 47. Sprengel pycnometer, first described by the German chemist Hermann Sprengel in 1873. He had used this instrument for a number of years. It had great precision and was easy to fill. Later the German chemist Wilhelm Ostwald partially modified it, replacing the original U tube with a single-sided one.
