Dispersion Technology manufactures a family of ultrasound-based instruments for measuring particle size, zeta potential, high frequency rheology, and solid content in concentrated systems without diluting them.[7]

Founders Dukhin and Goetz have written two books published by Elsevier describing the details of these methods, underlying theories, and applications of the instruments manufactured by Dispersion Technology.[8]

Co-Founder Dr. Andrei Dukhin and his father Dr. Stanislav Dukhin were the subject of a 2009 feature in the American Chemical Society documenting their research done in the former Soviet Union; their contributions to the fields of electrokinetics, colloid science, DLVO theory, etc.; and their immigration to the United States as a part of the Soviet Scientists Immigration Act of 1992.[3]

Dispersion Technology maintains seven patents in the United States,[9][10][11][12][13][14] and has representation in Japan,[15] Russia,[16] Europe,[17] Brazil,[18] South Korea,[19] China,[17] and Canada.[20]
