Rubotherm Prezisionsmesstechnik develops, produces and
sells measuring instruments and laboratory plants for process engineering. The
main emphasis of our work is placed on gravimetric measuring methods for
recording mass changes under controlled environments. In the 1980''s the company
founders from the Ruhr-Universitat Bochum developed a new method whereby
samples could be weighed in closed vessels without any contact. The principle
is as follows: a sample is weighed from the outside by means of a new kind of
magnetic suspension balance (which has been patented worldwide) and the
suspension force is contactlessly transmitted from the pressurized measuring
cell to a microbalance at ambient atmosphere. This means that mass changes of a
sample can be recorded even under extreme conditions with the utmost accuracy.
Since the mid 80''s these magnetic suspension balances have been applied to
fundamental research work with enormous success. Numerous requests, including
many from industry, induced the developers to set up the company Rubotherm
Prezisionsmesstechnik GmbH in 1990, located in the Ruhr Technology Centre
in Bochum. Our weighing technology has since then been enjoying an even wider
circle of application throughout the world in both research and industry.
