Platinum crucibles and dishes

Platinum crucibles and dishes are essential for the proper performance of chemical tests as well as to ensure good sample preparation.

Range of platinum crucibles and dishes 

IAM Drijfhout’s range includes more than 100 different standard crucibles and dishes in a variety of shapes, sizes and alloys. Some examples of design and size choices include:

  • volumes from 2.5 ml to 750 ml with either a round or flat bottom.
  • the option of reinforced rims or bottoms (reinforcement helps to prevent deformation and cracks thus increasing the lifespan of the product).
  • some models of crucible and dish are available with a spout for easy pouring, while other models such as the GD-series pour well without a spout due to their unique shape.

Alloys 

Our crucibles and dishes are available in the following alloys:

  • 100% platinum 
  • 95% Pt / 5% Au (platinum/gold) 
  • 97% Pt / 3% Rh (platinum/rhodium) 
  • 90% Pt / 10% Rh (platinum/rhodium) 
  • 97% Pt / 3% Ir (platinum /iridium) 

The most commonly used alloy, especially in the oil and petrochemical industries is platinum/gold. It offers the following advantages: 

  • Increases crucible strength 
  • Decreases premature wrinkling
  • The tendency for recrystallization is diminished 
  • Samples are easy to remove 

IAM Drijfhout also offers stabilized crucibles and casting dishes made by adding zirconium dioxide (ZrO2) to the platinum-gold alloy.

Platinum lids for crucibles and dishes

Crucibles and dishes can be used with a heat-resistant lid made of a similar alloy. The lids are loose-fitting to allow gases to escape during the heating process. All our standard crucibles and dishes can be fitted with a lid. In general, a lid will not be used in order to allow for direct contact with oxidizing agents.
