The Penta-Pycnometer is capable of measuring the true density of solid materials. Up to five specimens can be loaded and purged simultaneously. Each of the five specimens is then analyzed automatically in sequence with no operator involvement. Each specimen can be analyzed automatically as many times as is required until a user-selected reproducibility is obtained or until a user-selected maximum number of runs is completed. The unit also features automatic calibration and automatic transducer zero reset prior to each run. Front panel LEDs display the operational status, and different sample cell sizes can accommodate a wide variety of samples.

Features:

  • Specimen volumes from 2 to 135 cubic centimeters
  • Specimen cell volumes of 4.5, 10, 50, and 135 cubic centimeters
  • Accuracy better than +/- 0.03%
  • Reproducibility better than +/- 0.015%
  • Self-calibrating with calibration values permanently maintained in memory until recalibration

Applications:

Pycnometers are currently used for research and quality control in such diverse industries as ceramics, catalysts, fillers, nuclear fuels, petrochemicals, carbon blacks, charcoals, fibers, minerals, cement, powdered metals, resins, and many others.
