DSC-40B Differential Scanning Calorimeter Introduction: Based on the tower heat flow method, DSC-40B is a conventional thermal analysis instrument that measures the heat flow difference between a sample and a reference sample per unit time as a function of temperature or time under programmed temperature control. This instrument requires only milligram-level sample amounts to determine key thermal analysis parameters such as enthalpy, melting temperature, crystallization temperature, glass transition temperature, specific heat capacity, purity, oxidation induction period, thermal stability, and Arrhenius kinetic constants. It provides core data support for material research and development, process optimization, phase diagram drawing, quality control, and failure analysis in various fields such as polymers, pharmaceuticals, food, organic and inorganic chemicals. Features: 1. Utilize mature tower thermal flow technology to enhance the resolution and sensitivity of the instrument 2. High-performance thermal flow sensor with antioxidant substrate achieves higher sensitivity and dynamic response, accurately captures micro-thermal changes, provides reliable baseline stability, and has a baseline drift of ≤100uW without baseline subtraction 3. The integrated silver furnace body design effectively reduces mutual interference between samples, ensures higher heat transfer efficiency, high sensitivity, and more precise temperature control 4. The temperature control range covers -90~550℃, meeting the temperature measurement needs of different materials 5. The instrument features three temperature control modes: cooling, heating, and isothermal 6. Equipped with analysis functions such as DSC Onset Point, Start set Point, Endset Point, baseline, heat flow peak, glass transition temperature, heat peak area, endothermic and exothermic enthalpy values, peak temperature, specific heat, etc 7. High-frequency data acquisition technology combined with structural optimization design provides reliable baseline stability and high signal-to-noise ratio, with baseline reproducibility of ≤40uW and heat flow peak-to-peak noise better than 8uW 8. Equipped with a high-definition touch screen, easy and quick operation of the instrument can be easily achieved Technical Specifications: Temperature range: -90~550℃ (imported advanced refrigerator is optional) Temperature control mode: cooling, heating, constant temperature (-70℃~400℃) Heating rate: (0.05~200) ℃/min Cooling rate: (0.1~100) ℃/min Temperature difference rate deviation: better than 1% Cooling method: mechanical cooling, air cooling Precision of phase transition temperature: ±0.02℃(In) Accuracy of phase transition temperature: ±0.1℃(In) Baseline stability: ≤100uW (-50~300℃, without deduction) Baseline reproducibility: ≤40uW Peak-to-peak noise of heat flow: better than 8uW Enthalpy measurement accuracy: ±0.08% (In) Accuracy of enthalpy measurement: ±0.8% (In) Indium peak height/half-peak width: ≥20.0mW/K TAWN resolution: R(20) ≤ 0.3 TAWN sensitivity: S(0.1)≥3 Sampling frequency: 50Hz Heat flow measurement range: ±750mW Gas circuit module: 3-channel gas circuit control, inert/oxidation, static/dynamic, 0~300mL/min
