MEDILAB Low Form High Alumina Crucibles are precision-engineered ceramic vessels designed for controlled high-temperature heating, melting, ashing, and calcination. Their shallow, wide-mouth form ensures stable sample handling, faster heat transfer, and excellent thermal uniformity. Built for demanding laboratory and industrial environments, these crucibles deliver consistent performance in applications where purity, temperature resistance, and chemical durability are critical.

 Key Features

  • High-purity Alumina construction (≈99%) for contamination-free analytical results
  • Low-form geometry provides stability, wide access, and rapid heating
  • Unglazed surface ensures minimal interaction with samples
  • Withstands operating temperatures up to ~1700–1750 °C
  • Excellent resistance to acids, alkalis, and corrosive media
  • High mechanical strength reduces breakage during heating cycles
  • Low porosity for reduced absorption and easy cleaning
  • Suitable for repeated high-temperature use in furnaces and muffle ovens

     Furnace support plates

Handling & Precautions

  • Heat gradually when starting a cycle; avoid thermal shock.
  • Allow the crucible to cool naturally—do not immerse a hot crucible in liquids.
  • Handle with proper laboratory tongs or gloves.
  • Clean with non-abrasive brushes/detergents to maintain surface integrity.
  • Avoid mechanical impacts or dropping on hard surfaces.
  • Store in a dry, dust-free environment to avoid contamination.

 Applications

Ideal for high-temperature and analytical procedures in:

  • Research laboratories and universities
  • Chemical, petrochemical, and materials science labs
  • Pharmaceutical R&D, QC/QA labs
  • Metallurgical testing, alloy studies, and thermal processing
  • Ashing, calcination, LOI (Loss on Ignition), fusion, and general heating procedures in low-form design facilitate rapid heating, easier handling of powders/solids, and uniform thermal exposure.
