Count Standards
Count standards are precise suspensions of polymer microspheres used as concentration reference materials to calibrate and validate particle counters, flow cytometers, and liquid sampling systems. Polysciences’ count standards (e.g. SureCount series) are traceably formulated and supplied at known bead densities for rigorous instrument QC.
