SureCount™ Particle Count Standards

SureCount™ standards are suspensions of polymer microspheres intended for the validation and monitoring of particle counters and supporting sample preparation processes. The diameters of the SureCount™ standards are traceable to NIST Standard Reference Materials. The standards are supplied as ~1 x 10⁶ microspheres / mL aqueous suspensions in 10mL volumes, and each bottle is provided with a Certificate of Traceability.
