    For Use With (Application) Airborne Optical Particle Counter Calibration

    Calibrate airborne optical particle counters (OPC) to comply with ISO 21501-4 regulations with the Thermo Scientific™ 4D Series Dry Microsphere Size Standards. Ideal for instrument manufacturers, as well as QA/QC managers in pharmaceutical, biotech and electronics manufacturing, these microsphere reference beads feature a calibration uncertainty—the range of values within which the actual mean diameter will lie—that is less than or equal to 2.5% of the mean diameter.

    The diameter is traceable to the National Institute of Standards and Technology (NIST), and the product’s Certificate of Calibration and Traceability provides the documentation needed for QC/regulatory programs and audits.

    • Mean size standard uncertainty of ≤2.5% enables calibration of air particle counters to ISO
    • Superior uniformity provides exact calibration point when setting the calibration curve
    • Diameter is traceable to NIST, a known government standard
    • Certificate of Traceability provides objective evidence for QC compliance
    • Available in 3µm, 5µm, 7µm and 10µm diameters
    • Conveniently packaged in dropper-tipped bottles for direct dispensing into sampling chamber
