Rectangular alumina crucibles offer a large, flat working surface, making them well suited to batch sample preparation, powder calcination and applications where samples need to lie flat rather than pool.
Labmina holds one of the widest ranges available — over 170 rectangular crucibles in 99% high-purity alumina, spanning 0.9ml to 4700ml, with and without covers. Every crucible is rated for continuous service to 1600°C.
For non-standard footprints or wall thicknesses, we manufacture rectangular crucibles to customer drawing. Browse the full size range below, or contact us for a custom quote.
