Micromeritics SediGraph

SediGraph III Plus – High-Accuracy Sedimentation Particle Size Analyzer

The Micromeritics SediGraph III Plus delivers precise and reproducible particle size distribution measurements using the sedimentation method based on Stokes’ law. By directly measuring particle mass through X-ray absorption, the SediGraph provides accurate equivalent spherical diameters across a range of 0.1 to 300 µm, even for complex or heterogeneous materials.

With a large 50 mL analysis volume, full particle accounting (including fractions outside the measurement range), and optional automation for up to 18 samples, the SediGraph III Plus ensures unmatched reliability and throughput. It conforms to ISO 13317-3 and ASTM standards B761 and C28, making it a trusted tool for both research and production quality control.

At Prisma Scientific, our experts provide training, method development, and ongoing support to ensure your lab achieves consistent, high-quality particle size data with every analysis.
