The DSC-40BE is a conventional Differential Scanning Calorimeter (DSC) based on the heat flux principle, designed for accurate thermal analysis of various materials. The instrument measures the difference in heat flow between a sample and a reference material as a function of temperature or time under controlled heating conditions.

With only milligram-level sample quantities required, the DSC-40BE provides comprehensive thermal characterization, including enthalpy, melting point, crystallization temperature, glass transition temperature (Tg), specific heat capacity, purity, oxidation induction time (OIT), thermal stability, and Arrhenius kinetic parameters.

The DSC-40BE is suitable for research, quality control, material characterization, and thermal stability studies across a wide range of applications.

Features

Supports ultra-low temperature operation down to -90 °C, enabling sub-zero phase transition and thermal stability analysis. Provides cooling, heating, and isothermal modes to support flexible thermal program control for diverse materials.
Equipped with a mechanical refrigeration system that provides stable cooling without reliance on external liquid nitrogen. Delivers high baseline stability (≤100 µW) to ensure reliable quantitative thermal analysis.
Features an integrated silver furnace design to enhance heat transfer efficiency and reduce sample-reference interference. Includes an HD touchscreen interface for intuitive and efficient laboratory operation.
Incorporates a high-sensitivity heat flux sensor for precise micro-thermal signal detection and improved dynamic response.
