High-performance tools for every measurement need
Whether you require simple single point viscosity measurements for a fast batch release in production, yield point measurements for quality control analyses, or comprehensive rheological investigations for the development of new formulations, we provide the full range of rheometers and viscometers for every application.
Types of laboratory rheometers
Rotational rheometers
Get ahead of the competition with modular advanced rheometer systems for faster, comprehensive material characterization. With accessories for practically every application and software for all user levels, Thermo Scientific HAAKE rheometers are versatile, innovative instruments proven to increase productivity with "Connect Assist" technology. Thermo Scientific HAAKE RheoWin Software is used with all HAAKE rheometers and enables easy transfer of measuring and evaluation routines between QC and R&D.
Types of laboratory viscometers
Falling ball viscometer
Accurately measure the absolute value of the kinematic viscosity of transparent Newtonian liquids and even gases. The Thermo Scientific HAAKE Falling Ball Viscometer C reliably determines the flow behavior of transparent Newtonian liquids and gases for applications in the chemical, pharmaceutical, food, and hydrocarbon industries.
Rotational viscometer
Measure flow behavior precisely, quickly, and simply with our rotational viscometers. They are ideal for tests and comparative measurements in quality control according to recognized standards. Portable viscometers measure viscosity in the lab, in the field, or in a production environment.
Types of On-line Process Control Rheometer
The HAAKE PCR online rheometer features innovative process control technology for online rheological measurements of melt index and melt viscosity for extrusion lines and melt pipelines.
Which rheometer or viscometer is right for you?
Handheld spindle viscometers for on-site viscosity measurements. Entry-level rheometers for absolute viscosity measurements with integrated temperature control. Research-grade rheometers for extended material characterization over the widest measuring range. Whatever your requirements, we can help you select the right rheometer or viscometer.
