适用于生产中会混入气泡的试样

比重瓶主要由一空心圆柱体和一活塞（在空心圆柱体的一端）所组成

旋转螺旋就将压力作用在试样上，压力的大小为150磅/平方英寸，多余的漆液被压出去。瓶子在最大压力下可以容纳100毫升或83.3毫升水

使用和清理都很方便，结果的重现性优于0.5%

Pressure Pyknometer Cup

(Weight Per Gallon Cup) Ref 1510
This instrument is suitable for testing samples which
may contain bubbles e.g. emulsion paints. The sample is compressed to 150 psi (10.3 bar) to reduce any
significant errors due to these inclusions. Density is
then calculated from the mass of the fluid and the
calibrated volume of the cylinder. The cup is easy to
use and clean and is capable of density reproducibility better than 0.5%.
