Intrinsic Stability of Asphaltenes in Oil
The SV10 revolutionizes the S-value testing for stability of asphaltenes , by introducing the first fully automated instrument complying with ASTM D7157, which includes a unique, temperature controlled, high precision measuring cell (patent pending).
The SV10 is bringing a major improvement in handling, accuracy and test duration. Straightforward and user friendly, the SV10 does not need any operator action during the test or application expert: it comes with all programs ready for the different sample types described in ASTM D7157.
3 different quantities of sample are automatically diluted with toluene. Then, by titrating those 3 mixes with heptane, the asphaltenes flocculate. The SV10 uses a high precision measuring cell (patent pending*) to detect the flocculation. Finally, the stability results are automatically computed.In addition, the SV10 eliminates all safety risks linked to the manipulation of hazardous solvents.
