Bulk Density(ρ B): Bulk density of a powder is the weight of loose powder sample in unit volume. ρ B =M/V In this video, Bettersize application engineer Shelly Zhang is measuring the bulk density of ...

Scientists have developed a way to measure the density of a single cell. The new method involves measuring the buoyant mass of each cell in two fluids of different densities. Measuring cell density ...

(Nanowerk Spotlight) The density of proteins in solution is an important fundamental biophysical quantity that has not been accurately measured yet. This has led to extensive debate in the literature ...

Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is ...
