Pycnometers are used to measure the density of fluids. Usually pycnometer volume is determined by measuring the mass and temperature of contained water and thereafter is used to determine the density of contained fluids by further weighing. Hie calibration and use of the pycnometer can be achieved on a modem electronic balance without the use of the usual set of mass standards. This paper explores the electronic balance application to pycncmetry, presents supporting data with analysis and discusses a pycnometer design.
INTROTOCTICNPycnometers are essentially flasks whose internal capacity has been determined by weighing the vessel em p ty and again when filled with water. The pycnometer
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
