SV10 Asphaltene Stability



ASTM D7157, ISO PAS 23263, CIMAC guidelines



The SV10 revolutionizes the S-value testing, 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.

In addition, the SV10 eliminates all safety risks linked to the manipulation of hazardous solvents.



  • Crude oils
  • Heavy fuel oils
  • Residues
  • Bitumens
  • Marine fuels (VLSFO, ULSFO, …)
  • Asphalten free oils
  • Tar sand crude oils
  • Emulsions



  • Marine
  • Refineries
  • Crude oil



The SV10 is a straightfoward automated instrument that strictly follows the test method ASTM D7157.  The test preparation is simplified and the test is run unattended, simultaneously, on the 3 positions.



Running a test with the SV10 is straightforward and very easy, the operator:


  1. Weight the sample(s)
  2. Position up to 3 samples in parallel on the SV10 
  3. Close the door and initiate the test(s)


Then the all procedure is automated: toluene dilution, heptane titration, measure of the flocculation point and cleaning. Detection curves are displayed in real time, and the SV10 computes the stability results according to the selected titration tests.



A detailed report of the titrations and S-value determinations are displayed and saved in the built-in database. They can be printed, transmitted to LIMS or copied to USB stick.


The final report includes:

  • Date & time, sample name & type
  • Xmin : minimum heptane consumption to reach the flocculation (ml/g)
  • FRmax : maximum flocculation ratio
  • S : S-value (intrinsic stability of the oil)
  • Sa : peptizability of the asphaltene
  • So : peptizing power of the oil
  • R2 : goodness of fit
  • Titration tests & linear regression graph
