Viscometer

The world’s most successful viscometer

Viscometer: Anton Paar‘s viscometer models have revolutionized viscosity measurement. The innovative SVM 3000 Viscometer and the further development of the well-known Höppler falling ball principle in the shape of the automatic micro-viscometer make precise viscosity determination easier and quicker than ever before.

Anton Paar‘s viscometer models are established as standard solutions and an increasingly popular alternative to traditional capillary viscometer types.The viscometer models are used in a wide range of industries: from wort measurement in beer to measurements on polymer solutions, inks, low-viscosity oils and applications in biotechnology and the pharmaceutical industry. For measurements on substances in which only a small amount of sample is available, a special accessory can be used.

Viscometer models from Anton Paar – more powerful than ever:

  • New firmware allows quick and easy operation and increases sample throughput by up to 50 %
  • Four precision levels available
  • Use of a sample changer with the unique Xpress technology fills samples with higher viscosity and reduces filing times
  • Sample recovery, automatic cleaning test and management of priority samples
  • Compact size, low solvent and power consumption

Anton Paar‘s viscometer models have revolutionized viscosity measurement.

Basics of Viscometry

Every single substance on Earth can be placed on a scale from fluid to solid. Viscometry is concerned with the determination of a fluid’s viscosity, that is its thickness or – more scientifically - its internal resistance to flowing.

External forces such as gravity affect the fluid and make it flow. Most substances change their viscosity depending on the external force. If a fluid’s viscosity remains constant independent of the external force it is called an ideal or Newtonian fluid.

One dominating influence on viscosity is temperature: the warmer it gets, the less viscous a substance becomes. Consequently, correct viscosity measurement requires precise temperature measurement and temperature control.

Basics of Lovis 2000 M/ME

The Lovis 2000 M/ME is a microviscometer based on the rolling ball principle.

  • A ball rolls through a closed, liquid-filled capillary which is inclined at a defined angle.
  • Inductive sensors determine the ball's rolling time between defined marks.
  • Both the liquid's dynamic and kinematic viscosity can be calculated from the rolling time.

Basics of Anton Paar Viscometer SVM 3000

The SVM 3000 uses the Stabinger measuring principle.

  • A lightweight magnetic rotor floats in a liquid filled tube, which rotates at constant speed. The rotor is centered by the centrifugal forces.
  • The sample fluid’s viscous forces drive the rotor. This leads to an equilibrium rotor speed, which is recorded as an unambiguous measure of the fluid’s viscosity.
  • The floating rotor and a contactless measuring sensor eliminate all undesirable influence of external friction.
  • A built-in U-tube oscillator for additional density measurement permits the simultaneous determination of density, kinematic and dynamic viscosity.

History of Viscometry (taken from Thomas G. Mezger “The Rheology Handbook, 2nd Edition, p. 252ff)


The word “viscosity“ is derived from the Latin word “viscum” for “mistletoe”. In the old days, mistletoe berries were used to make a sticky kind of glue for catching birds.

75 BC: Titus Lucretius Carus, poet and philosopher, writes a didactic poem on the flow and gliding behaviour of fluids like water, milk, wine, olive oil and honey.

1590: Galileo Galilei introduces the systematic use of practical scientific experiments, e.g. on liquids and solids to characterize a material’s behavior.

1649: Blaise Pascal reflects about ideal fluids without any flow resistance.

1687: Isaac S. Newton states proportionality between flow resistance and flow velocity for fluids.

Since 1800: Use of efflux viscometers (flow cups) for textile printing inks and oils.

1839: Gotthilf Heinrich Ludwig Hagen designs the first capillary viscometer.


History Micro Viscometer Lovis 2000 M/ME

1845: Georges Gabriel Stokes performs scientific falling ball experiments.

1933: Fritz Höppler designs a “Falling-Ball Viscometer” (commercially available since 1934 (see also DIN 53015, and later ISO 12058).

1985: For Anton Paar KG, Dr. Jorde and Dr. Ribitsch of the Institute for Physical Chemistry at the Karl-Franzens-University of Graz develop a rolling ball viscometer with automatic angle selection, optical detection and water bath temperature control.
 
1988: Anton Paar KG introduces the AMV 200, an electronic microviscometer with inductive sensors, which also permits the measurement of opaque liquids. The inclination angle can be varied from 15° to 90°.

1999: Anton Paar GmbH presents the AMVn automatic microviscometer as the successor to the AMV 200. Thermoelectric temperature control (Peltier elements) replaces the water bath system.

2011: Lovis 2000 M/ME is introduced as a new generation of microviscometer which is part of Anton Paar’s successful M Generation.
