Anton Paar Launch New SVM 4001 Stabinger Viscometer for Lubricating Oils

The SVMTM series of viscometers from Anton Paar has been expanded with the new SVM™ 4001 Stabinger Viscometer™. It has a double-cell system for viscosity measurements at two different temperatures simultaneously, providing the fastest Viscosity Index determination from the lowest sample volume.

The innovative double-cell design of SVM™ 4001 allows for simultaneous measurements at 40 °C and 100 °C. As each of the measuring cells also contains an integrated density oscillator, density measurements according to ASTM D4052 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 D2270 as well as API calculations are automatically shown on the touchscreen.  

Moreover, SVM™ 4001 allows for simultaneous determination of viscosity and density at any two temperatures between 15 °C and 100 °C. This state-of-the-art SVM™ model also provides viscositytemperature extrapolation according to ASTM D341 and freely selectable API grades which are shown on the 10x4” touchscreen. SVMTM 4001 provides an unbeatable combination of features that simplify the measurement process. Both density cells are equipped with the FillingCheck™ technology compliant with D4052 requirements, which allows real-time monitoring of the filling quality of the density cells. This saves valuable time as bubbles are already detected during the measurement.

SVMTM 4001 is designed to provide Viscosity Index, kinematic viscosity and density of lubricating oils, base oils and additives, as well as in-service oils. In addition, the optional modular combination with Anton Paar refractometers allows for fast determination of the carbon-type composition of transformer oils with automatic calculations according to ASTM D2140 and D3238. In order to maximize productivity and meet the demands of high throughput, SVMTM 4001 can be used with a 71-position sample changer.
