  DRI-CAL Particle Size Standards


These products are provided for calibrating particle sizing and counting instrumentation that require dry particles. 

   Product Detail


DRI-CAL Particle Size Standards are conveniently packaged in dropper-tipped vials in 1 gram quantities, enabling the user to dispense the microspheres directly into the sampling chamber.  They are not suitable for dispersion in liquid media.

Each package of standards contains a Certificate of Calibration and Traceability to NIST which includes a description of the calibration method and its uncertainty, and a table of chemical and physical properties. A Material Safety Data Sheet with handling and disposal instructions is also included. Packages are lot-numbered for technical service and support after the sale.
