The Labor-Platina Ltd. in Hungary (EU) manufactures, produces, sells, repairs platinum crucibles, also after your drawing.

The material
The commonly used material for Labware is iridium alloyed platinum PtIr5 (Pt95% and Ir5%), for special claims gold alloyed platinum PtAu5 (Pt95% and Au5%) is also used.
Because of the high risk of the deformation or damaging the use other materials, like pure platinum or gold, is only recommended, if the Labware has minimum double thick walls.

The shape
The listed product parameters show you only our basic series. Our standard shape you can see on the pictures and the drawing here. With technical drawings and data we can fulfill other claims, too, but it would grow the costs of the production and also the price.
