Gas displacement pycnometry – the fastest, easiest and most accurate measurement of the true density of solids, powders and particles

 

  • True and skeletal density – helium (or N2/Ar/dry air) gas pycnometry
  • 20-30% faster measurement with AccuTemp temperature control (±0.025°C)
  • Volume accuracy 0.02%, repeatability 0.01%
  • Compliant with a range of ASTM/ISO/USP standards (e.g. USP <699>, ISO 12154, DIN 66137)

Details

  • Model: AccuPyc III 1350 (current generation – see note about the photo below)
  • Nominal cell volume: 10 cm³ (0.1/1/3.5 cm³ inserts) or 100 cm³ (10/35 cm³ inserts)
  • Gases: helium (standard for skeletal density), nitrogen, argon, dry air – no recalibration needed when switching
