Dri-Cal Particle Size Standards
Dri-Cal 50 micron Particle Size Standards for calibration of particle sizing and counting instruments that require dry particles for size response. Each bottle includes a Certificate of Calibration and Traceability to NIST, which includes a description of the calibration method and its uncertainty; Table of chemical and physical properties; Material Safety Data Sheet (MSDS). Typically sold in 1 gram volume per bottle, but can be special ordered at higher volume per bottle. Dri-Cal 50 micron particles are not suitable for dispersion in liquid media.
