A Precision pycnometer comprises a container(11) storing liquid, and a capillary conforming to the height of liquid to scale(15,19). The thickness of pipes(12,17) are formed larger than overall thickness of the container. The diameter of the capillary is formed very smaller. The capillary consists of a first capillary(13) and a second capillary(18) parallel to each other, extended from the container.</p> |
