DSC, TGA/DSC, DMA, and TMA
Upon heating, the Glass Transition is defined as the temperature range at which all non-crystalline and semi-crystalline materials transition from a "frozen" state to a phase in which cooperative rearrangement of molecules occurs continuously, in addition to molecular vibration and rotation. The rearrangement of molecules typically occurs over a range of several nanometers.
Glass transition is commonly used in the characterization of plastics and other amorphous or semi-crystalline materials. For some applications, glass transition is also useful in determining the usable temperature range.
METTLER TOLEDO products that can determine Glass Transition include DSC, TGA/DSC, DMA, and TMA.
MP55, MP70, MP80, and MP90
Melting Point is defined as the temperature at which a substance changes phase from a solid to a liquid. Melting point determination is used in research and quality control to identify and check the purity of a wide range of crystalline substances. You can also investigate color changes, clear points, and decomposition temperatures with video observation.
Melting range is used for substances where it is hard to find a defined melting point temperature. The melting range is the temperature range from the point at which the substance begins to melt to the point at which the substance has completely transitioned to a liquid state.
METTLER TOLEDO products that can determine Melting Point include the MP55, MP70, MP80, and MP90.
Cloud Point is defined as the temperature at which an aqueous solution becomes turbid or "cloudy".
Knowing the cloud point of your solution helps in determining the best performance temperature range of your material. This is a unique property of some substances, such as surfactants, foaming agents, coatings, and paints. It is used as a quality control parameter in chemical and petrochemical industries, and it is used in the measurement of surfactants, such as detergents and soap, in the cosmetics industry.
METTLER TOLEDO products that can determine Cloud Point include the MP80.
MP55 and MP80
Slip Melting Point is the melting point of waxy solids. Slip melting point is defined as the temperature at which a sample has softened sufficiently to rise in an open capillary tube.
It is used to characterize raw and formulated products that do not have a well-defined melting point such as fats, oils, and waxes in the food and beverages industry, the cosmetics industry, and the petrochemical industry.
METTLER TOLEDO products that can determine Slip Melting Point include the MP55 and MP80.
DP70 and DP90
Softening Point is defined as the temperature at which a substance has flowed a certain distance under defined test conditions.
Softening points are mainly used in quality control but can also be valuable in research and development to determine the use temperatures and process parameters of many different materials. Depending on the substance softening it may be necessary to promote the flow by applying a ball weight. This aligns with the METTLER TOLEDO Cup-and-Ball methods for resins (ASTM D6090-12) and for asphalt and pitch (ASTM D3461-14). Our instrument generates a novel length diagram which indicates the rheological behavior of the sample.
METTLER TOLEDO products that can determine Softening Point include the DP70 and DP90.
DP70 and DP90
Dropping Point is defined as the temperature at which the first drop of a substance falls from a cup under defined test conditions.
Similar to softening point, dropping points are mainly used in quality control but can also be valuable in research and development to determine the use temperatures and process parameters of many different materials. Dropping point is essential to determining the thermal property of substances without a defined melting point such as pitch, asphalt, polymers, resins, and waxes. The dropping point of substances is regulated by different industry standards.
METTLER TOLEDO products that can determine Dropping Point include the DP70 and DP90.
Boiling Point is defined as the temperature of a substance going from the liquid phase to the gas phase.
Boiling point can be used to determine the identity or purity of a substance. Knowing the boiling point of a liquid can help in selecting the optimal process temperature, and can also give you additional information on ideal storage conditions. Boing point is used in the pharmaceutical industry for active pharmaceutical ingredients and organic solvents. In the petrochemical industry, it is used for final products and solvents. In the chemical industry, boiling point is used for organic solvents and mixtures. And in academia, it is used to find the mixed boiling point for phase diagrams and steam distillation.
METTLER TOLEDO products that can determine Boiling Point include the MP80.
