A thermal analysis crucible serves as sample containers for thermoanalytical measurements. METTLER TOLEDO offers a wide range of high-quality DSC and TGA crucibles to cover virtually any thermal analysis application such as polymer melting, crystallization and glass transitions. Available in many types of materials, pan sizes and shapes, our crucibles handle almost any kind of samples and for all possible measurements, including high-pressure applications.
METTLER TOLEDO crucibles are engineered to provide optimum heat capacity and thermal conductivity to maximize the resolution and sensitivity of your DSC measurement.
A wide range of ambient and high-pressure crucibles are offered to cover almost any application or sample type. Crucibles are available in various shapes, sizes and materials including aluminum, alumina, copper, gold, glass, PCA and steel.
METTLER TOLEDO's precision-designed crucibles provide flat bases and thus optimum heat transfer. Different sealing possibilities can be used to restrict gas exchange between the sample and surrounding atmosphere.
All crucibles can be easily loaded or removed from the TGA or DSC measuring cell—either manually or automatically—using the sample robot. Automatic lid removal and piercing before measurment prevents the uptake of moisture and sample contamination.
According to the International Confederation for Thermal Analysis and Calorimetry (ICTAC), thermal analysis is group of techniques in which a physical property of a substance is measured as a function of temperature while the substance is subjected to a controlled temperature program.
Thermal analysis crucibles serve as containers for samples used during a thermal analysis measurement. Crucibles also protect the sensor from contamination during the measurement. The type of crucible used for a measurement can influence the quality of the results obtained. Thermal analysis crucibles are available in many materials and sizes, ensuring that there will be a crucible available for any application. Considering the relevant factors of the measurement, sample, and crucible type can help produce more reliable thermal analysis results.
Crucibles are needed for DSC, TGA and TGA/DSC measurements, and in some cases, crucibles provide a useful solution for sample preparation during TMA measurements.
There are several factors to consider when selecting a thermal analysis crucible. One must take all factors into account to ensure that the crucibles selected will provide the best results for any DSC, TGA or TGA/DSC measurement. Factors to consider: crucible material, crucible volume, crucible mass, sample under examination, sample robot, experimental conditions (temperature range of measurement, atmosphere, thermal analysis technique used)
