Part Numbers

Metacup CE – Without tellurium
Metacup C – With tellurium


Metacups are disposable measuring cups for the thermal analysis of iron. The cups are made of high-grade silica sand and are fitted with a strong and dependable connecting system. The volume of the cups offers the best compromise between measuring time and consistency of the measuring results. They have a quartz protected, high-grade type K thermocouple. If white solidification is required, the Metacup™ – C cups have a special tellurium mixture cemented on the cup’s bottom.

Metacup™ – CE. Does not have tellurium. It is used for the carbon equivalent determination of cast iron.

Metacup™ – C. Has tellurium for the reliable thermal analysis reading of CE, C and Si of cast iron.

Handling and Storage

The cups are made of fragile materials and must be handled with care. Metacups should be kept in a dry environment.

The advantages of a Square Cup versus a Round Cup

  • Square cup makes contact with metacup holder pins in two locations thereby eliminating risk of loose contacts
  • The thermocouple junction is protected by a quartz tube
  • Tellurium mixes homogeneously with the metal
  • Metal starts cooling uniformly from the corners so results are consistent
  • The thermocouple wire is thicker and can withstand higher temperatures
