Because only with the Beekman Pycnometer can you make volume measurements accurate to better than O.lcc in just 47 seconds. Even on surface active materials. And tests are non-destructive, too. No liquids. No gas pressures. No temperature control needed. Just you and your Pycnometer. So fling away the flask and see your nearest Beekman Laboratory Apparatus Dealer or write direct for Data File PYC-13-163.
