Product Brochures
Crucibles serve as containers for samples during DSC and TGA measurements. They guarantee that the sensor is not contaminated during the measurement.
Crucible 160 uL, Al, 40 pcs, pin
Al 160 uL, 100 pcs, with pin.Aluminum Crucibles
160 μL Al crucibles for DSC measurements
The perfect aluminum crucible for samples with a weak signal that require a high sample mass.
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.
No usage of furnace expander required
The crucible can be used without furnace expander if the lid is reversed (maximum volume reduced to approx. 150 μL).

Al 160 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.
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.
Al 160 μL pan with standard lid
Most frequently, the 160 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 160 uL 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.
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)."
