Counting Beads PolyAn

Counting Beads are highly monodisperse PMMA microparticles with a known particle number
concentration, intended for use as counting standards for flow cytometers, particle and cell counters, as well as single-cell dispensing applications.
The Counting Beads can be tailored to your specific application: They are available in various sizes, ranging from 5–20 μm, as transparent beads, dye-colored (non-fluorescent) beads, or fluorescent beads encoded with either one fluorophore (single-channel) or multiple fluorophores (multi-channel) at emission wavelength (color) and emission intensities of your choice.
