High-purity open and lidded alumina sample boats sized to slide cleanly inside laboratory quartz and ceramic tube furnaces.
Sintered 99.5% and 99.8% alumina combustion boats are contoured specifically for horizontal tube furnaces, CVD deposition zones, and elemental combustion analyzers. Smooth unglazed interiors with minimal surface roughness prevent powder sticking during thermal decomposition, solid-state sintering, metal oxide reduction, and sulfur/carbon analysis.
Offered with pull-holes/handles for push-rod retrieval, semicircular or flat bottoms, and optional sliding covers to reduce vapor loss in flowing carrier gas.

Reference values reflect typical sintered, fused, or wrought grades. Exact batch test figures are confirmed on your written quotation and accompanying lot Certificate of Analysis.
Specify boat overall length × top width × height, wall thickness, alumina purity, pull-handle/hole style, lid requirement, and the inside diameter (ID) of your furnace tube so radial clearance can be verified.
Include target quantity, destination country/postal code for express air freight calculation, and any special cleanroom bagging or certification requests.
