This invention discloses a method for measuring the volume of irregularly shaped sealed containers, addressing the problem of inaccurate volume calibration of irregularly shaped sealed containers using existing direct water filling methods. The method includes: first, evacuating the irregularly shaped sealed container under vacuum; then, constructing a measuring device using a transparent flexible tube, a vacuum device, and a water-filling container; allowing ultrapure water to enter the irregularly shaped sealed container under the pressure difference created between air and the container; simultaneously, using the vacuum device to assist in filling the container with ultrapure water; and finally, calculating the volume of the irregularly shaped sealed container by combining the weight of the container before and after water filling with the density of the ultrapure water. Compared to the direct water filling method, this invention ensures that the irregularly shaped sealed container is completely filled with water, leaving no gaps or air bubbles, thereby improving the accuracy of volume measurement.
