Rolling-ball viscometer:
Lovis 2000 M/ME
- Measures dynamic viscosity and relative viscosity from only 100 µL of sample
- Powerful polymer software automatically delivers intrinsic viscosity, molar mass, K-value, and more
- Referenced in US and European Pharmacopoeia
upon request
in specific countries
Lovis 2000 M/ME is a rolling-ball viscometer which measures the rolling time of a ball through transparent and opaque liquids based on Hoeppler's falling ball principle. The instrument is mainly used for viscosity measurements of low viscous liquids for R&D applications, in the pharmaceutical and chemical industries. A measurement with Lovis 2000 M/ME can yield dynamic viscosity, intrinsic viscosity, molar mass of a polymer and more.
Key features
