New Opaque Size Standards

Following the success of the company’s 10 – 100 micron polydisperse clear glass standards, Whitehouse Scientific has prepared a new 500 kg
batch of an opaque version of the glass beads.
The particle size standard is subdivided into single-shot bottles from 2.5 g down to 100 mg making it suitable for all particle sizing methods, from laser diffraction and image analysis to optical zone sensing devices analysing either in the dry state or as a suspension.
The standards are all NIST traceable and have been analysed by more than
20 laboratories covering a range of techniques including laser diffraction, image analysis and sieve analysis.
