VISCO BALL

 

The VISCO BALL viscometer measures accurately the viscosity of transparent Newtonian liquids and gases (with a special glass ball). It is preferably used in research, in processing control and in quality control. lt meets the requirements of DIN 53015 as well as ISO 12058 standard and it is accepted as an official reference instrument. Its measuring accuracy when backed up by the precise temperature control of a FUNGILAB circulator is not surpassed by any other type of viscometer.

According to the Höppler principle, the time taken by the ball to travel the reference distance through a glass tube which is filled with the sample and inclined by 80º is measured and the test results are given as dynamic viscosity in the internationally standardised absolute units of milli Pascal (mPa·s). 

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 solutions,…). 

Main Features

• 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.
