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.
