Proven Technique and Reliability
The new SediGraph® III Plus determines particle size by using the highly accurate and reproducible sedimentation technique which measures the gravity-induced settling rates of different size particles in a liquid with known properties. This is simple yet extremely effective technique for providing particle size information for a wide variety of materials.
For over three decades, the Micromeritics SediGraph has remained the standard instrument for particle size analysis in many laboratories throughout the world. Whether in a rugged production environment or a controlled laboratory setting, the SediGraph continues to produce accurate results with superior reliability. Particle size distribution is measured using the sedimentation method. Particle mass is measured directly via X-ray absorption. By measuring the rate at which particles fall under gravity through a liquid having known properties as described by Stokes’ law, the SediGraph determines the equivalent spherical diameter of particles ranging from 300 to 0.1 micrometers.
The new generation SediGraph III Plus combines this proven technique with new technology to deliver reproducible and highly accurate particle size information, completing most analyses in minutes.
Intelligent Design Features
The SediGraph III Plus offers advanced instrumentation features that ensure measurements are repeatable and easy to perform. New features make it easier to operate and maintain the instrument, and the results can be reliably reproduced by SediGraphs in other locations.
Design improvements include:
- High-precision x-ray tube with a lifetime warranty (7-years)
- Windows operating software with Ethernet connectivity provides point-and-click selection, networking, printer selection, cut-and paste, and much more
- Utilization of a simplified pumping system ensures fast and easy maintenance
- Reduced noise level for a quieter working environment
- A maintenance reminder, based on the number of analyses performed, alerts you when it is time for routine maintenance
- 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 particle settling velocity and grain size in Phi units
