Sedimentation particle size analyzer Micromeritics

Micromeritics’ new generation SediGraph III 5120 particle size analyzer combines the proven SediGraph analytical technique with advanced instrumentation features to provide superior repeatability, accuracy, and reproducibility in the size range of 300 mm to 0.1mm. In addition, complete particle accountability assures that all of the introduced sample is accounted for. The SediGraph III measures mass by X-ray absorption and particle size by sedimentation– no modeling is required.


The SediGraph III promises the same dependable results as its predecessor, but with greater ease-of-use and reporting power. Computer-controlled mixing chamber temperature improves repeatability and reproducibility. A highly versatile and interactive reporting system provides a wide range of custom data presentation options and now includes grain size in Phi units and particle settling velocity. Statistical Process Control (SPC) reporting and regression analyses are also available. SediGraph II 5100 files can be utilized by the SediGraph III, allowing a seamless transition to the new system.


The SediGraph III is fully automatic. Combined with the optional MasterTech 052 Autosampler, up to 18 samples can be queued to run sequentially and completely unattended, including automatic stirring or sonication prior to transfer to the analysis system.
