Absorptometer “C”

The Absorptometer “C” Data Acquisition System determines oil absorption in compliance with ASTM D 2414 as well as ASTM D 3493 including new procedures B and C (carbon black) as well as with ASTM D 6854 (silica).

It consists of the following major components:

  • Frequency inverter drive unit with precise torque measurement
  • High-precision measuring mixer with special blades
  • High-precision burette, variable programmable titration rate for the optimum test procedure
  • 64-bit software for Windows VISTA, Windows 7 and Windows 8

The user-optimized, modern 64-bit software of the Absorptometer “C” offers numerous advantages for daily laboratory use:

  • Continuous operation at low cost: Mixer-specific determination of the TLS (= torque limit switch) and all other important data
  • System normalization as per ASTM with standard reference carbon blacks, including the possibility of normalization with other than standard carbon blacks
  • Normalization trends show mixer wear
  • Choice between local and remote operation
  • Automatic saving of tests in remote operation
  • Definition of test lists and test patterns
  • Full burette control via PC, incl. variable programmable titration rate for quick titration at the beginning and reduced rates during the significant test phase
  • Separate selection of operator and printout language
  • Evaluation fully meets ASTM D 2414 incl. new procedures B (end-point at 70 % of maximum torque) and C (end-point at fixed but reduced torque level)
  • Calculation of 3rd order polynomial in the significant part of the torque curve
  • Manifold graphics options
  • One PC can handle up to 4 instruments with 2 or more interchangeable mixers each


  • Carbon Blacks
  • Silica
  • Fillers
  • Pigments
  • Titanium dioxide
  • Cosmetic powders and pigments
