Durable Differential Scanning Calorimetry Machine for Precise Thermal Measurement of Plastics Polymers and Material Testing
Brief introduction of the instrument:
Differential Scanning Calorimetry (DSC) is a classical thermal analysis technique designed to characterize thermal effects of materials under programmed temperature conditions. It is extensively employed across materials science and chemistry sectors—including R&D, process optimization, quality control, and failure analysis—for its high precision and versatility.
DSC enables systematic investigation of key material properties: phase transitions of inorganic materials, melting and crystallization behaviors of polymer materials, polymorphism of pharmaceutical compounds, and the solid-liquid phase ratio of oils and fats.
Instrument use:
Differential Scanning Calorimetry (DSC) enables precise quantification of heat-associated physical and chemical changes in materials, covering key parameters including:
- Glass transition temperature (Tg)
- Melting point and melting temperature
- Crystallization behavior and crystallization enthalpy
- Phase transition reaction enthalpy
- Thermal stability
- Curing/crosslinking processes
- Oxidation induction period (OIP)

FAQ:
Q1: What is the core working principle of a DSC machine?
A1: The DSC machine operates by measuring the heat flow difference between a sample and an inert reference material as both are subjected to a programmed temperature cycle (heating, cooling, or isothermal). This enables quantitative analysis of heat-associated physicochemical changes in the sample, such as phase transitions, melting, crystallization, and thermal decomposition.
Q2: What key physicochemical properties can a DSC machine test?
A2: It can precisely quantify critical parameters including glass transition temperature (Tg), melting point (Tm), melting enthalpy, crystallization behavior, crystallization enthalpy, phase transition enthalpy, thermal stability, curing/crosslinking degree, and oxidation induction period (OIP).
Q3: What are the typical temperature range and temperature accuracy of a standard DSC machine?
A3: Standard models offer a temperature range of -150 °C to 700 °C (extendable to 1500 °C for high-temperature variants). Temperature accuracy is ±0.1 °C, with temperature resolution up to 0.01 °C—ensuring precise control of the programmed temperature cycle.
Q4: Which materials are compatible with DSC testing?
A4: It is widely applicable to polymers (plastics, rubbers, fibers), inorganic materials, pharmaceuticals, food ingredients, oils and fats, composites, and other materials requiring thermal property analysis—covering R&D, quality control, and failure analysis scenarios.
Q5: Does the DSC machine comply with international testing standards?
A5: Yes, it fully complies with major international standards such as ISO 11357 (polymers), ASTM E967/E968 (general DSC methods), GB/T 19466 (plastics), and USP <891> (pharmaceuticals)—ensuring test results are recognized globally.
Q6: What is the sample requirement for DSC testing, and how is data processed?
A6: The recommended sample weight ranges from 2–10 mg (depending on material type). The machine is equipped with a high-sensitivity heat flow sensor (sensitivity ≤0.1 μW) and professional analysis software, which automatically records test curves (heat flow vs. temperature/time) and calculates key parameters. Data can be exported in Excel/CSV/PDF formats for further analysis.
Q7: What maintenance is required for the DSC machine, and what is the service life of core components?
A7: Routine maintenance includes annual calibration of temperature and heat flow (using standard reference materials like indium), and regular cleaning of the sample pan. Core components (sensor, heating/cooling module) have a service life of ≥50,000 test cycles. We provide calibration protocols and technical support for maintenance.
Q8: Can the DSC machine be customized for specific testing needs?
A8: Yes, customization options are available, including extended temperature ranges (low-temperature cryogenic modules or high-temperature furnaces), specialized sample pans (hermetic, pressure-resistant), and tailored software functions (e.g., kinetic analysis modules for curing reactions)—adapting to unique application scenarios.
