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.
For R&D
• Small sample amount (starting from 100 μL)
• Sample recovery
• Wide temperature range (-30 °C to 100 °C /-22 °F to 212 °F)
• Wide viscosity range (0.3 mPa.s to 10,000 mPa.s)
• High accuracy
• Variable inclination angle for testing shear-dependent flow behavior
For pharmaceutical and medical labs
• Included in US and European Pharmacopoeia
• Pharma qualification packages available
• Optional modular combination with Anton Paar instruments for measuring density, refractive index, turbidity and pH value
• Flow-through filling for large sample throughput
For the chemical industry
• Hermetically closed system for volatile or toxic samples
• High chemical resistance (borosilicate glass or PCTFE)
• Special polymer measuring and evaluation features
• Automatic filling using autosampler
• Testing of opaque samples
