3 Scenarios When Density of Microspheres Matters in Research

Does Density of Microspheres Matter for Fluid Suspension?

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.

Deformable Silver Coated PMMA Microsphere Spacers

PMPMS AG 1 5 125 150um 480x480 Deformable Silver Coated PMMA Microsphere Spacers

Silver Coated Glass Microspheres work well for increasing the conductivity of bond lines, but they lack the capability to deform when compressed to give increased conductive contact between the surfaces of the bond line.? These newly released Silver Coated PMMA Microspheres offer the low weight deformable pmma cores, and 250nm thick silver coating for high conductivity. Conductivity of this…

Density Marker Beads

Density marker beads offer enable excellent stratification, and bright coloration for high visibility with the unaided eye. Density marker beads of accurately known mass density are generally used as an external marker to facilitate the monitoring of the density gradient shape and range. Historically density calibration beads in the size ranges of 212-250um or 250-300um are used.

FDA-Approved Microspheres

What makes a microsphere FDA-approved? In order to tell whether the microsphere can be used in cosmetics, food, or medical devices it is important to look at the raw materials that are incorporated into the microsphere during manufacturing process.? For example, unpigmented or clear polyethylene microspheres supplied by Cospheric in sizes from 10 micron to 1000 micron meet the…
