Differential Scanning calorimeter (DSC)Oxygen Induction Time (OIT)

Brief introduction of the instrument:

Differential scanning calorimetry (DSC) technique is widely applied. The differential scanning calorimeter serves as both a routine quality testing tool and a research instrument, measuring the temperature and heat flow associated with internal thermal transitions in materials. Our instrument is a heat flow type differential scanning calorimeter, featuring good repeatability and high accuracy, which is particularly suitable for precise specific heat measurement. The equipment is easy to calibrate, uses low - melting - point materials, is fast and reliable, and has a very broad application range, especially in material research and development, performance testing, and quality control. Material properties such as glass transition temperature, cold crystallization, phase transition, melting, crystallization, product stability, curing/crosslinking, oxidation induction period, etc., fall within the research scope of differential scanning calorimetry. Different models should be selected according to experimental parameters and requirements.

Instrument use:

Measurement of curing reaction temperature and thermal effect in polymer materialsMeasurement of material phase transition temperature and thermal effectMeasurement of crystallization, melting temperature and thermal effect in polymer materialsGlass transition temperature testing of polymer materials, etc.
