Fungilab Höppler Viscometer

Viscoball

  • The Viscoball measures accurately the viscosity of transparent Newtonian liquids and gases (with a special glass ball).

 

Features

  • Changeable angle

 

Fixed angle

  • Complies with DIN 53015 / ISO 12058

 

Kit of 6 balls

  • Wide viscosity range covered

 

Simple thermostatic

  • Measuring with easy conection to our thermovisc series

 

Viscosity readings

  • Dinamic (cP or mPa·s)
  • Kinematic (cSt)
  •  Reproducibility: 0.5%
  • Comparability: 1%

 

Viscosity range

  • 0.5 - 10^5 mPa·s (cP)
  • 0.5 - 105 mPa·s (cP)

 

  • High accuracy through improved visibility of falling ball.
  • Minimized test time due to accurate return run of the ball.
  • Reduced cost of ownership through increased life time of falling tube.
  • Extended re-calibration periods through improved bearing support.

 

The VISCO BALL viscometer is mainly used for low viscosity substances such as used in:

  • Mineral oil industry (oils, liquid hydrocarbons).
  • Food industry (sugar solution, honey, beer, milk, gelatine, fruit juice).
  • Chemical industry (polymer solutions, solvents, resin solutions, latex dispersions, adhesive solutions).
  • Cosmetic/Pharmaceutical industry (raw materials, glycerine, emulsions, suspensions, solutions, extracts).
  • Petroleum industry (light crude, machine oil, crude petroleum).
  • Fuels (petrol, diesel oil, paraffin).
  • Paper industry (emulsions, pigment dispersion, paper additives).
  • Paints and varnishes (printing inks, varnishes, water lacquers, inks).
  • Detergents (liquid washing agents, washing-up liquids, tenside solu- tions).

 

Measuring principle

The rolling and sliding movements of a ball through the sample liquid are timed in an inclined cylindrical measuring tube. The sample viscosity is correlated to the time a ball requires to traverse a definite distance. By turning the measuring tube upside down again the return of the ball may also be used for an additional measurement applying the return cons- tant. The test results are given as dynamic viscosity in the internationally standardized, absolute units of mPa·s.
