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.

HAAKE Falling Ball Viscometer C

  • Measures viscosity precisely using only a stopwatch and no power connection
  • Provides accurate measurement of the viscosity of transparent Newtonian liquids and gases.

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.

HAAKE Viscotester 3 Rotational Viscometer

  • Smart alignment given by design and visualized by an electronic level
  • Quick coupling of measuring geometries for fast and easy adaptation
  • Color coded geometries and a geometry range indicator ensure correct rotor selection every time

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.
