This bulb is an example of scientific glassware. The stopcocks on either end serve as valves. Typically, the bulb would be vacuum-evacuated, then filled with a gas sample from an experiment. The bulb could then be moved to an analytical instrument, such as mass spectrometer or gas chromatograph. There, the bulb gas would be extracted into this instrument for analysis – typically determination of the components and their concentrations.
