When is the density of microspheres important? Density of microspheres controls the buoyancy of each particle and its behavior in a system or process. Let’s look at three scenarios: (1) suspension of microspheres in a specific fluid, (2) fluid flow, performing flow visualizations, or particle image velocimetry, and (3) simulation or modeling of objects with specific density.
Santa Barbara, CA, December 6, 2013 – Cospheric LLC, a microsphere manufacturing and distributing company, expanded their line of density marker beads which now offers six different densities including 1.02 g/cc (fluorescent green), 1.04g/cc (fluorescent orange), 1.06g/cc (fluorescent violet), 1.08 g/cc (dark blue), 1.09 g/cc (fluorescent red), and 1.13g/cc (fluorescent blue).

In the biomedical industry researchers are sometimes looking for cells having targeted specific gravities. In order to locate these cells in test tubes it is useful to have colored marker beads which will show where the delineation between specific densities occurs. Two microsphere products having densities of 1.065 g/cc and 1.075 g/cc were recently released. These spheres are offered with density tolerances of ?0.005 g/cc enabling excellent stratification, and bright blue and red coloration for high visibility with the unaided eye.
