Innovative technologies revolutionise viscosity measurements

Apr 19 2017 Read 459 Times

Anton Paar’s innovative technologies have revolutionised viscosity measurements to provide solutions for every application in the petroleum industry:

  • SVM™ technology - for your oils and fuels
  • RheolabQC – the rotational rheometer for your bitumen and asphalt products
  • Lovis 2000 M/ME – the rolling-ball viscometer for dilute polymer solutions

Anton Paar's new SVM™ 3001 is a highly precise viscometer with an integrated density measuring cell. A single measuring cycle on a small sample volume yields kinematic viscosity, density, dynamic viscosity, viscosity index, and more. One combined measuring cell covers the entire measuring range for viscosity, density, and temperature and is filled in one go. A minimum sample amount of only 2 mL is sufficient for multiparameter results according to standards. The SVM™ 3001 has a wide measuring range from -60°C to +135°C with unprecedented heating/cooling rates of up to 20°C/min, allowing for measurements of samples ranging from jet fuel to crude oils, heavy fuels and waxes. As the heating is electrical, no thermal transfer liquids are needed for temperatures down to -20°C.

The innovative double-cell design of SVM™ 4001 allows for simultaneous measurements at 40°C and 100°C from a single syringe. As each of the measuring cells also contains an integrated density oscillator, density measurements according to ASTM D4052 and ISO 12185 at each temperature are simultaneously performed. The minimum sample volume needed for Viscosity Index determination and the density measurements is only 2.5 mL. The Viscosity Index results according to ASTM D2270 as well as freely selectable API calculations are automatically shown on the touchscreen.

RheolabQC is a very robust and reliable rotational rheometer that determines the dynamic viscosity of bitumen and asphalt at elevated temperatures. The viscosity determination correlates with ASTM D4402, AASHTO T316, and (DIN) EN 13302, whereby a maximum temperature of +180°C can be applied. Besides quick single-point viscosity determinations, more sophisticated rheological tests such as the determination of flow curves or even an asphalt’s temperature-dependent flow behavior can be performed. Ease of use is guaranteed due to Toolmaster™ (automatic measuring system recognition), QuickConnect coupling (fast and easy mounting of the measuring system), and the Peltier temperature device (fast heating (8 K/min) and cooling rates (4 K/min)). Disposable aluminum cups minimise cleaning efforts and maximise sample throughput – especially suited for your asphalt and bitumen measurements.

The Lovis 2000 M/ME microviscometer from Anton Paar enables fast and highly accurate viscosity measurements of polymer solutions with automatic calculations of up to 13 polymer parameters. Lovis 2000 M/ME offers unique polymer software features, enabling simple and automatic determination of intrinsic viscosity, molar mass, relative viscosity, and other polymer-specific parameters. With its built-in Peltier thermostat, the rolling-ball capillary viscometer provides high-precision temperature control. Lovis 2000 M/ME is often used for low-viscosity liquids but can also be used for viscosity measurement on samples with a viscosity of up to 10000 mPa.s at any temperature from 5°C to 100°C. Lovis 2000 M/ME is also suitable for measuring highly corrosive samples. Due to excellent chemical resistance of the PCTFE capillaries, Lovis 2000 M/ME can be used for chemicals as corrosive as hydrofluoric acid.

If you want to measure the viscosity of any other samples – be sure we can provide a perfectly suited solution for your application.
