  • Unique self-sealing lids form airtight seals around the crucible's ground rim
  • During a volatiles run, the lid automatically rises to expel accumulated gases
  • Lid sinks back to restore the seal and form an oxygen-free atmosphere to prevent sample ashing
  • Produces more reproducible results than conventional methods
  • During moisture and ash determinations, the lid keeps sample moisture-free
  • Eliminate inaccurate weighings caused by moisture uptake
  • Perform proximate analysis to determine moisture, volatiles, ash, and fixed carbon on the same sample
