Chemically-Stable Al2O3 Ceramic Combustion Boats Acid Alkali Resistant Alumina Lab Ware for Laboratory Equipment Parts

Analytical and research laboratories demand vessels that contribute nothing to the sample and survive everything the method throws at them. Our Chemically-Stable Al2O3 Ceramic Combustion Boats and Lab Ware are formed from high purity alumina, a material whose chemical stability spans concentrated acids, strong alkalis, molten salts and the oxidizing atmosphere of combustion analysis at temperatures beyond the reach of quartz and porcelain.

The dense, glazed-free surface sheds sample residues easily and resists the thermal shock of repeated furnace cycling. Because alumina is completely inorganic, boats can be fired clean and reused without organic contamination, while trace element levels are controlled so that even sensitive gravimetric and spectrometric methods see no interference from the vessel.

• Broad chemical stability: Resists mineral acids, caustic alkalis, halogens and oxidizing fluxes across the working temperature range.
• High temperature capability: Suitable for combustion and ashing work to 1700°C, beyond the limit of fused quartz.
• Thermal shock resistance: Survives rapid insertion into and removal from hot furnaces during routine analysis.
• Low trace contamination: Controlled purity body minimizes blank values in elemental and gravimetric analysis.
• Residue release surface: Smooth dense surface releases ash and combustion residues for easy cleaning between runs.
• Reusable and cleanable: Boats can be reignited to constant weight and reused hundreds of times.
• Complete lab ware range: Boats, crucibles, dishes, tubes and combustion accessories in standard and custom sizes.

These vessels serve laboratory equipment parts in elemental analyzers, thermogravimetric analyzers, combustion furnaces, muffle furnaces, ash determination ovens, sample preparation systems and general analytical chemistry work in research, quality control and testing laboratories.

We supply both catalog laboratory ware and custom vessels for instrument manufacturers, including special shapes that fit automated sample handling systems.

Laboratory ware is individually wrapped in foam and packed in partitioned cartons to prevent chipping of rims and corners during shipment.

Every batch is inspected for dimensional accuracy, surface defects and firing quality, with certificates available for laboratory accreditation records.
