Anton Paar

Anton Paar is a privately held Austrian precision measurement instrument company founded in 1922 in Graz, Austria, that manufactures instruments for measuring density, viscosity, concentration, and structural properties of materials across research, quality control, and industrial process applications. The company's digital density meters, based on the oscillating U-tube principle pioneered by Anton Paar scientist Hans Stabinger and collaborators, are the reference standard for accurate liquid density and concentration measurement in the pharmaceutical, beverage, chemical, and petroleum industries, with their DMA series instruments installed in virtually every quality control laboratory worldwide. Their Lovis rolling ball and SVM Stabinger viscometer-density meter combinations provide precise kinematic and dynamic viscosity measurements essential for lubricant formulation, polymer characterization, and process fluids. Anton Paar's rheometers, including the MCR series modular compact rheometers with temperature control and extensional rheology accessories, are trusted in academia and industry for characterizing the flow and deformation behavior of polymers, gels, colloids, emulsions, and biological fluids. Their small-angle X-ray scattering (SAXS) instruments, particularly the SAXSpoint and Empyrean SAXS platforms, are widely used for nanostructure characterization of polymers, proteins, and nanomaterials in solution and solid state. Anton Paar's microwave synthesis reactors for the Monowave series accelerate organic synthesis in research labs, and their autoclave systems support hydrothermal synthesis of zeolites, MOFs, and other porous materials.
