| Abstract: | Typical instruments for the measurement of the density of a liquid may not be used in microscale experiments efficiently and satisfactorily. Although a few methods to determine the density of a liquid at the microscale level have been developed, these methods can determine the density to only two significant figures.To improve the precision and accuracy in measuring the density of a liquid at the microscale level, a capillary with a volume of about 30 �L and two pinhole ends has been designed. The density determined by this capillary method is precise to four significant figures. |
