Crucibles serve as containers for samples during DSC and TGA measurements. They guarantee that the sensor is not contaminated during the measurement.
Pan 100 uL, Al, 400 pcs
Aluminum 100 μL pans.Set of 400 crucibles without lids. This large crucible is used for DSC measurements. It allows you to use larger quantities of sample if the signal obtained from the sample in a 40 µL pan is too weak.
100 μL Al crucibles for DSC measurements
The 100 μL aluminum crucible is the most frequently used crucible type for DSC (and TGA) measurements with larger samples. Package size: 100 pans.
Excellent thermal conductivity
The perfectly flat base of the pan ensures excellent thermal contact and minimizes artifacts.
Various lids available
Three lid types can be combined with the 40 μL pans: standard lids, lids for piercing by the robot, and lids with a prepierced 50 μm hole.

Al 100 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 100 μL pan with standard lid
Most frequently, the 100 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 100 μL pan with special lids
The pan can be combined with other special lids: a) With an aluminum lid that contains a prepierced 50 μm hole. Useful if evaporation is critical. b) With an aluminum lid that is used for piercing by the piercing device before transfer to the furnace.
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)."
