- - - - Measurement of oxygen
        
        A measured mass of living organism is put in the chamber
        
        First the spring clip is open, so the equilibrium of pressure and temperature is set between chamber and surroundings
        
        After 5 minutes pass, the spring clip is closed and the movement of colored liquid along the capillary tubes is observed
        
        The experiment is repeated for a few times
      - Measurement of carbon dioxide
        
        To detect carbon dioxide released, We should use indicator solution.
        
        ex) Hydrogen carbonate indicator - purple at high pH (alkaline), red around neutral pH and orange yellow at low pH (acidic)
