Since its inception in 1982, Quantum Design (a privately held corporation) has developed and manufactured automated temperature and magnetic field testing platforms for materials characterization. These systems offer a variety of measurement capabilities and are in widespread use in the fields of physics, chemistry, biotechnology, materials science and nanotechnology.

Quantum Design Inc. (QD) is the manufacturing arm of QDI. Located in San Diego, California, QD is the leading commercial source for automated materials characterization systems incorporating superconducting technology. QD instruments may be found in the world's leading research institutions, and have become the reference standard for a variety of magnetic and physical property measurements. Quantum Design Inc. instruments are cited in, and provide the data for, more scientific publications than any other instrument in the fields of magnetics and materials characterization. This means that each year, literally hundreds of scientific publications, advancing the science of materials, use data generated from QD instruments.

Recently, Quantum Design Inc. expanded its product line beyond material characterization, to include instruments such as: a compact IR Crystal Furnace for the creation of new material; a Superconducting High-Gradient Magnetic Separator (SHGMS) for the processing and improvement of Kaolin clay; and a full line of Advanced Technology Liquefiers (ATL) and Helium Recovery Systems for the conservation and recycling of helium (a vital and increasingly scarce resource essential for cryogenic research and instrumentation).

In diverse areas such as materials characterization, high-sensitivity electrical measurements, and in-lab helium conservation, Quantum Design's team of scientists and engineers provides a full spectrum of service and application support for customers both domestically and internationally.


Quantum Design International has been active in Latin America since 1998. In 2010 the Latin American office was opened in Brazil to meet the needs of the sizable and growing research base using Quantum Design Equipment. The office is fully operational where new features are continually being added to facilitate activities for researchers. We are fortunate to be able to represent a very good line of other scientific instrumentation companies to service Latin America.
