DSC analyzer STA3000

processcrystallizationstability

Overview
STA synchronous thermal analysis combines TGA with DSC/DTA to acquire TG and DSC/DTA data simultaneously from the same sample in a single run.

Application
Suitable for research and development, process optimization and quality control in plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic and metal materials, and composites.

Measured parameters

• DSC: melting and crystallization, phase transitions, reaction temperatures and enthalpies, combustion heat and specific heat capacity.
• TG: thermal stability, decomposition, REDOX behavior, adsorption, free water and gypsum content, compositional analysis by mass change.

Structural advantages

• Furnace heated by double-row winding of alloy wire: nickel-chromium (STA2000) or platinum-rhodium (STA3000) to reduce interference and improve high-temperature performance.
• Tray sensor in nickel-chromium (STA2000) or platinum-rhodium (STA3000) alloy for high-temperature, oxidation and corrosion resistance.
• Separated power supply and circulating cooling components to reduce thermal and vibration influence on the microbalance.
• Open-top furnace design for convenient operation, minimizing furnace movement and protecting sample rods.
• Insulation isolating furnace heat from chassis and microbalance.
• Interchangeable furnace body available per customer requirements.

Key features

• 32-bit ARM Cortex-M3 processor for faster sampling and processing.
• 24-bit four-channel AD acquisition for DSC, TG and temperature signals.
• Independent control of power and water-cooling parts by 8-bit MCU for coordinated isolation.
• USB two-way communication for remote operation and parameter control via PC software.
• 7-inch 24-bit full-color touch screen with on-screen TG calibration.
