Whitehouse Scientific has extended its range of glass microspheres from 10 microns down to 1.5 microns with the addition of a certified range of silica microspheres for particle sizing applications.
In addition to their use in particle sizing, these silica microspheres have applications in areas such as drug delivery, respiratory studies and filter testing.
Supplied as dry powders in sets of five with each vial containing 0.2g, they can be used as either wet suspensions or in the dry form.
Highly spherical and having a narrow size distribution, the microspheres are traceable to the NIST international reference standard using a precision microscope method that corrects for any pixel asymmetry in the camera sensor.
Analytical precision is confirmed using certified discs on a National Physical Laboratory particle reference graticule and three-dimensional NIST-traceable latex standards.
