Expertise description

Rubotherm is specialized in analytical instrumentation for sorption measurements, measuring of thermo physical properties and thermogravimetry as well as laboratory plants for process study and optimisation. R&D expertise is offered in design, engineering and automation of high-end analytical equipment, hard- and software engineering for process automation, chemical engineering and chemistry. An application laboratory providing measuring and testing facilities is available.

Besides its standard product range Rubotherm offers especially engineered instruments and laboratory testing facilities, some of them using also the technology of our magnetic suspension balances. For instance multi-bed PSA and TSA adsorption pilot plant for breakthrough curve measurement of complex mixtures, cycling instruments for testing the durability of adsorbent materials, and fixed bed reactors for testing of catalysts under process conditions have been realized, to name a few.

We are experienced in European and national funding programmes.

FlexiDOSE

What we offer

Gas & vapor dosing, mixing and pressure control devices for feeding external reactors or instruments with measuring atmospheres at exactly defined composition and pressure.

The FlexiDOSE is the perfect completion for the IsoSORP and DynTHERM instruments. The automatically operated FlexiDOSE devices can generate gas and/or vapor mixtures with controlled composition and regulate the pressure of the atmosphere extremely stable and accurate.

Besides the combination with the balance instruments the FlexiDOSE devices are the ideal tool for researchers searching for an automatic device to operate reactor systems or laboratory processes.

The FlexiDOSE instruments are fully automatic operated by PC control. Its standard gas connections allow easy combination and integration with existing autoclaves or reactors.
