State-of-the-Art and Precision Differential Scanning Calorimetry Machine for Thermal Analysis of Thermoplastics

Differential Scanning Calorimetry (DSC) is a widely recognized thermal analysis technique specifically tailored for the thermal characterization of polymers and polymer blends, including:

• Thermoplastics (polymers, moulding compounds, and other moulding materials--with or without fillers, fibres, or reinforcements)
• Thermosets (uncured or cured materials--with or without fillers, fibres, or reinforcements)
• Elastomers (with or without fillers, fibres, or reinforcements)

DSC is engineered for the observation and quantitative measurement of various intrinsic properties and associated thermal phenomena of the aforementioned materials, such as:

• Physical transitions (e.g., glass transition; phase transitions including melting, crystallization, and polymorphic transitions)
• Chemical reactions (e.g., polymerization, crosslinking, and curing of elastomers and thermosets)
• Oxidative stability
• Heat capacity

Equipped with an LCD liquid crystal display with blue backlight, it presents abundant real-time information--including set temperature, sample temperature, oxygen flow rate, nitrogen flow rate, differential thermal signal, and the status of various switches--enabling comprehensive monitoring of test parameters.

The USB communication interface offers strong universality, stable and uninterrupted data transmission, and supports an automatic reconnection function--ensuring reliable connectivity during long-duration testing processes.

• The furnace body features a compact design with a stepless adjustable heating rate, flexibly adapting to diverse temperature-rise requirements for different test scenarios.
• The installation process is optimized with a full mechanical fixing method, which completely eliminates the risk of differential thermal signal contamination by colloids inside the furnace--effectively safeguarding test data accuracy.

This design ensures high repeatability of sample temperature measurement, addressing the limitations of single-probe systems:

• A temperature probe mounted on the furnace wall implements PID control of the overall furnace temperature. However, thermal inertia causes a certain deviation between the furnace wall temperature and the actual sample temperature, and this deviation varies with seasons.
• To resolve this issue, an additional temperature probe is installed at the bottom of the sample to measure its real-time actual temperature. Combined with our proprietary temperature control technology, the furnace wall temperature is precisely regulated to make the sample temperature reach the set value--significantly reducing errors in both differential thermal signals and temperature data.

A digital gas mass flow meter enables automatic switching between two gas atmosphere flows. It features fast switching speed and short stabilization time--maintaining consistent and reliable atmosphere conditions throughout the test cycle.

• Standard samples are provided to facilitate customers' calibration of temperature coefficients, simplifying routine verification operations.
• A dedicated furnace cooling interface is integrated to support rapid furnace cooling, shortening the interval between consecutive tests and improving work efficiency.

The software adapts to computer screens of various resolutions, automatically adjusting the curve display mode according to the screen size. It is compatible with both laptops and desktops, and supports operating systems such as Win2000, XP, VISTA, and WIN7.

It supports user-programmable test protocols to realize automated testing workflows. The software offers dozens of built-in instructions, allowing users to flexibly combine and save instructions based on their specific test procedures--simplifying complex operations into one-key execution.
