Product Brochures
Crucibles serve as containers for samples during DSC and TGA measurements. They guarantee that the sensor is not contaminated during the measurement.

Aluminum crucible with pin.Aluminum Crucibles
Aluminum crucibles with pin
The most frequently used crucible type for DSC measurements is the 40 μL aluminum crucible. Package size: 100 pans with pin/100 standard lids.
Excellent Thermal Conductivity
The flat base ensures perfect thermal contact. Pans with pin are recommended if reproducibility is critical. They cannot be used with a robot.
Two lid types available
There are 2 lid types that can be combined with the 40 μL pans: standard lids and lids with a prepierced 50 μm hole.

Al 40 μL crucible description
The most frequently used crucible type for DSC (and TGA) measurements is the 40 μL aluminum (standard) crucible. It is very shallow (low in height) and has a strong flat base, which ensures good thermal contact by limiting the thermal gradients.
Al 40 μL pan with standard lid
Most frequently, the 40 μL pan is used in combination with a standard lid into which a large hole has been pierced. In this case the atmosphere in the crucible is practically the same as in the furnace but substances are prevented from creeping out.
Al 40 μL crucible hermetically sealed
The crucible can be hermetically sealed to suppress endothermic evaporation, vaporization or sublimation when carrying out DSC measurements on volatile substances. The maximum permissible overpressure that the sealed lid withstands is 0.2 MPa.
Al 40 μL pan with a special lid
The pan can be combined with an aluminum lid that contains a prepierced 50 μm hole. Useful if evaporation is critical.
Plunger/die set for sealing
For these crucibles, the standard die/plunger set (ArtNo 27809 and 27386) is used; the set is included when buying the standard crucible press.
Aluminum background information (I)
Aluminum crucibles have a high purity of 99.9%. The maximum usage temperature of the crucibles is 640 °C. At the surface, a thin alumina (Al2O3) layer forms if the crucibles are kept in an ambient atmosphere.
Aluminum background information (II)
"... However, this alumina layer is not always perfect; therefore, experts recommend treating crucibles for critical experiments for about 15 min at 400 °C in an air atmosphere. A hazardous substance in combination with aluminum is mercury (poison for Al)."
