Versatile Differential Scanning Calorimeter for Analysis of Polymer Melting Point and Phase Transition Temperature
Specification:
1. Display System
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—ensuring comprehensive monitoring of test parameters.
2. Communication Interface
The USB communication interface boasts strong universality, stable and uninterrupted communication, and supports an automatic reconnection function—guaranteeing reliable data transmission during long-duration testing processes.
3. Furnace Structure
- The furnace body adopts a compact design with stepless adjustable heating rate, flexibly meeting diverse temperature-rise demands for different test scenarios.
- The installation process is optimized with a full mechanical fixing method, which completely eliminates the risk of colloid inside the furnace interfering with the differential thermal signal—effectively ensuring the accuracy of test data.
4. Dual Temperature Probe Design
This design ensures high repeatability of sample temperature measurement, addressing the limitations of single-probe systems:
- A temperature probe mounted on the furnace wall is used for 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.
5. Gas Atmosphere Control
A digital gas mass flow meter enables automatic switching between two gas atmosphere flows. It features fast switching speed and short stabilization time—maintaining stable and reliable atmosphere conditions throughout the test.
6. Calibration & Cooling Functions
- Standard samples are provided to facilitate customers' calibration of temperature coefficients, simplifying routine verification operations.
- A dedicated furnace cooling interface is designed to support rapid furnace cooling, shortening the interval between consecutive tests and improving work efficiency.
7. Software Performance
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 protocols to realize automated test procedures. The software offers dozens of instructions, allowing users to flexibly combine and save instructions based on their specific test steps—simplifying complex operations into one-key operations.

Overview of DSC Technology
Differential Scanning Calorimetry (DSC) is a classic thermal analysis method that measures heat effects under programmable temperature conditions. Currently, it has been extensively applied in various scenarios across the material and chemical industries, including research and development (R&D), process optimization, quality control, and failure analysis.
By using the DSC method, researchers can study phase transitions of inorganic materials, melting and crystallization processes of polymers, polymorphism of drugs, and solid-liquid ratios of oils and other food products. This technology is widely utilized in fields involving plastics, rubber, coatings, food, pharmaceuticals, biomaterials, inorganic materials, metal materials, and composite materials.
