Custom Alumina Crucibles, Made to Your Drawing

When a standard crucible doesn’t fit your process, Labmina manufactures custom alumina crucibles, boats, plates and labware to your exact specification.

What we can make

We fabricate custom parts in 99% high-purity recrystallised alumina, rated for continuous use to 1600°C. Cylindrical, conical, rectangular, boat and bespoke geometries are all possible — including non-standard wall thicknesses, custom volumes, holes, slots, flanges and ground or polished surface finishes.

How to order

Send us a drawing or a clear description of what you need: dimensions, tolerances, quantity and the application. Our team will review feasibility and send a quote. For prototypes and small runs, there is no large minimum order.

Why Labmina

We already hold one of the widest standard alumina ranges available — over 460 crucibles, boats and plates — so most “custom” requirements are a modification of a form we make every day. That means faster turnaround and lower tooling cost than starting from scratch.
