This firm has extended its range of glass microspheres from 10 microns down to 1.5 microns with the addition of a new certified range of silica microspheres. 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 powder in sets of five with each vial containing 0.2 g, they can be used as either a wet suspension or in dry form. — Whitehouse Scientific Ltd., Waverton, U.K.
