An apparatus for detecting defects in porous elements including systems and methods for quantifying acoustic signal data. A transducer receives acoustic signals generated within a test chamber by a porous element. A signal processing device may be included for analyzing the acoustic signals received, for quantifying the acoustic signals, and for correlating the acoustic signals with physical attributes of the porous element.

System and method for testing the integrity of porous elements

An expressor for varying the amount of fluid in a variable-volume container connected to at least one conduit includes a housing defining an enclosed chamber which can accommodate the container. The housing has at least one opening through which a conduit can extend. A pressure regulating mechanism is coupled to the housing to vary the pressure of fluid in the chamber and thereby vary the volume of the container.
