Pressure (A) and pump volume (B) during a pressure depletion experiment with n-propane. The bulk phase bubble point is crossed at about t ~ 0.4 h but no gas nucleates yet. Only after reducing the pressure further, at t ~ 0.7 h gas nucleates in the pore space displacing practically all liquid from the pore space in the field of view as shown by the μCT cross sections on the right.
