1. Key Features

  • Claisse molds and crucibles are made of 95% platinum, alloyed with 5% gold and are of exceptional purity. We also offer zirconium crucibles.
  • Available in a variety of sizes and thicknesses, our Pt/Au (95/5) molds and crucibles are in stock for immediate deliveries.
  • Our heavy molds and crucibles are recommended because they have a longer useful life, better resistance to high temperatures and can be polished several times.
  • Claisse has many precious metal accessories for your laboratory needs (dishes, tongs, tweezers, spatulas, special products and more).
  • If your molds become damaged, Claisse offers a polishing service to repair their surfaces and recover their mirror aspect. If you want to do it in your laboratory, Claisse offers a polishing kit, reshaper and a training program.
  • Claisse offers all our customers a scrap buyback program for used molds and crucibles as credit towards new platinum accessories. This precious scrap metal buyback policy applies to all other platinum, rhodium and gold accessories your laboratory uses.

2. Optimix Crucible

The Optimix Crucible prevents the aggregation of particles in the center. The sample is completely dispersed within a few seconds and the melt is fully and continuously overturned. Due to the three side dimples, the melt also spurts against the crucible wall initiating upward and downward agitation. Therefore, the Claisse Optimix Crucible:

  1. Promotes rapid dissolution of the sample.
  2. Significantly improves homogenization melt.
  3. Decreases the fusion process time.
  4. Contributes to preserving volatile elements such as Na, K, S and Cl. Remember that for volatile elements, you should keep the fusion temperature as low as possible and the fusion time as short as possible.
  5. Helps clean bubbles from the molten mass. Often, the decomposition of nitrates or carbonates during the fusion process creates a crust that may be pushed up to the rim of the crucible by the evacuating gases, and eventually causes overflow and loss of material. The crucible's three dimples break the side of the crust allowing the gases to properly escape.
  6. Makes dry oxidation directly on the fluxer easier and softer.

3. 110° Angle Mold

  • Our new mold with walls at a 110° angle significantly reduces the stress on the glass disk sides, thus minimizing possible cracking. This special mold is highly recommended for iron ores and copper sulfide samples.

4. Bis! Crucible

  • The Bis! Crucible has a small indentation in the bottom, which considerably increases agitation efficiency, thus increasing the speed of sample dissolution.
