Dri-Cal Particle Size Standard

Dri-Cal™ Particle Size Standards are particle size standards for instruments that require dry particles. These products are provided for calibrating particle sizing and counting instrumentation that require dry particles. They are available in a wide range of uniform, NIST traceable nominal diameter sizes from 5 μm up to 100μm. Dri-Cal Particle Size Standards are conveniently packaged in dropper-tipped vials in 1 gram quantities, enabling the user to dispense the particles 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.
