|Particle Size Standards --- HS Series|
These NIST traceable particle standards have been designed to calibrate or validate particle sizing systems which do not directly count particles but which are able to determine their sizes.
Each particle diameter will be supplied in a 20ml dropper-tipped-bottle with a certificate of calibration.
The advantage of this series is the high solids content of 2% or 3% for sizes below or above 1µm.
Available particle diameters: 180nm - 80µm
