About Lab Alley Self-Sealing Quartz Crucibles

• 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
