DSC analyzer STA2000

rubberfor quality controlfor pharmaceutical products

Overview
STA2000 synchronous thermal analyzer combines TGA (thermogravimetric analysis) with DTA or DSC to record TG and DTA/DSC signals from the same sample during a single run. Designed for laboratory R&D and quality control, it provides high-resolution temperature and mass-change data across a wide temperature range.

Applications
Widely used in plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic and metal materials, composites, and materials research for process optimization and quality monitoring.

Measurement and research characteristics

• DSC: melting/crystallization, phase transitions, reaction temperatures and enthalpies, combustion heat, specific heat capacity.
• TG: thermal stability, decomposition, redox processes, adsorption, free water and binder content, component proportion calculations.

Structural advantages

• Furnace heated by double-row winding of nickel-chromium alloy wire (STA2000) for reduced interference and high-temperature resistance.
• Tray sensor made of nickel-chromium alloy for high temperature, oxidation and corrosion resistance.
• Power supply and circulating cooling sections separated from the main unit to minimize heat and vibration impact on the micro-thermal balance.
• Open-top structure for easy sample loading and reduced risk of damaging the sample rod.
• Main unit equipped with insulation to isolate furnace heat from the chassis and micro-thermal balance.
• Interchangeable furnace body available on request.

Controller and software

• 32-bit ARM processor (Cortex-M3) for fast sampling and processing.
• 24-bit four-channel AD sampling for DSC, TG and temperature signals.
• Independent control of power and water-circulation parts by an 8-bit microcontroller; cooling subsystem managed in coordination with the host.
• USB two-way communication enables remote operation and PC control of instrument parameters, start/stop functions.
• 7-inch 24-bit full-color touch screen for local operation; TG calibration available on-screen.
