Rheometers & Viscometers

Measure and analyze the rheological properties of a wide range of liquid, paste and semi-solid samples with the Thermo Scientific™ HAAKE™ Viscotester™ iQ  and Viscotester iQ Air rheometers. The Viscotester iQ rheometer is an intuitive solution designed to meet the daily rheological requirements of QC labs. The Viscotester iQ Air rheometer is the smallest commercially available oscillation air bearing rheometer in the world. Both set new standards in modularity, ease of use, increased efficiency, and intelligent user guidance, from simple viscosity determinations to complex rheological investigations.

HAAKE Viscotester iQ Rheometers are the replacement for the discontinued Thermo Scientific™ Viscotester™ 550 Rotational Viscometer.

The development of the next generation Viscotester was driven by the demands of new rheological tasks in quality control. With the HAAKE Viscotester iQ rheometer, we combine decades of experience in rheology with solutions designed for highly dynamic working environments. Our goal is to enable fast, reliable and precise rheological measurements with maximum ease of operation. Now with the HAAKE Viscotester iQ Air rheometer, we bring you the smallest available oscillation air bearing rheometer. Either rheometer can be used as a standalone portable unit or as a fully software-controlled part of your QC lab.
