Heat-flow calorimeter DSC3000

DSClow-temperaturehigh-temperature

Product overview
Designed to determine internal thermal transitions by measuring the relationship between temperature and heat flow, the DSC3000 is a heat-flux differential scanning calorimeter suitable for polymer R&D, performance testing and quality control. The instrument provides high accuracy and repeatability, supports simple calibration and a wide range of laboratory applications including specific heat measurement.

Applications
The DSC is used to study glass transition, cold crystallization, phase transitions, melting, crystallization, stability, curing/crosslinking and oxidation induction. Typical uses include polymer curing temperature and enthalpy, phase-change temperature and enthalpy, polymer crystallization and melting analysis, and glass transition determination. Sample types: solids, liquids and viscous samples (gases generally excluded).

Working principle
The sample and reference are placed in crucibles and heated under a controlled program. Thermal events in the sample produce a temperature difference relative to the reference, visible as peaks on the DSC/DTA curve. Peak direction indicates exothermic or endothermic processes; the number, position, area, height and shape of peaks characterize the thermal events. The device records heat flow difference (mW) versus time or temperature.

Performance advantages

• New furnace design improving resolution and baseline stability.
• Digital gas flow meter for controlled purge gas flow and direct data recording.
• Two-way control (instrument and software) with an intuitive interface.
• Cortex-M3 ARM core controller for faster processing and stable temperature control.
• USB two-way communication for data exchange.
• 7-inch 24-bit color LCD touchscreen for local operation.
• Alloy sensor with enhanced corrosion and oxidation resistance.

Experimental principle (summary)
DSC measures the power difference between sample and reference under controlled temperature programs; ordinate: heat flow difference (mW); abscissa: time or temperature. Baseline and peak behavior allow interpretation of thermal events (endothermic/exothermic) and their characteristics.
