Helpers of all sizes for analysts

Precious analysis tools ranging in size from a shot glass to a rain barrel

Geologists analyze soil samples, the oil industry studies crude oil, and the steel industry wants to know the composition of slag. These are completely different fields, but all begin the analysis process with a high-temperature fusion treatment of the samples. But what equipment should be used for the fusion process? Platinum crucibles are ideally suited for the job, and are used in industrial and scientific laboratories around the world. Heraeus is a leading global manufacturer of platinum crucibles. It is remarkable that after over 130 years, we are still finding ways to improve this product.

Crucibles, casting dishes and boats made of precious metals are standard laboratory equipment for preparing samples for X-ray fluorescence analysis (XRF), for microanalysis, for fusions and for ashing. Larger iridium crucibles are used for growing single crystals from high-melting oxides (e.g., sapphire) for the optical and laser industries. Good chemical resistance to aggressive media, the high melting point and stability at high temperatures are key properties that have characterized platinum and platinum alloys in laboratory equipment for decades. Since 1870, Heraeus has been producing standard and customized laboratory equipment at its facilities in Hanau with a high degree of vertical integration and in a vast range of sizes.
