STA4001 is a new lifting STA synchronous thermal analyzer that can measure TG/DSC at the same time. The instrument adopts an automatic lifting furnace structure design, which makes it more convenient to test samples. It is also equipped with a digital flow meter that can automatically control the size of the gas. The software has been upgraded, and the analysis is more accurate. The instrument can be connected to infrared, making it more powerful.
Test scope
STA4001 lifting STA synchronous thermal analyzer can detect two kinds of information, TG/DSC, at the same time, and can measure a wide range of information, including: thermal stability, redox, decomposition behavior, corrosion research, decomposition kinetics analysis, melting/crystallization, solid phase transition, crystallinity, glass transition, etc.
How it works
STA4001 lifting synchronous thermal analyzer is based on the temperature change of the sample and the conduction, absorption, radiation and other processes of heat. It controls the temperature of the heating furnace to heat, cool and maintain constant temperature of the sample, and then detects and records the temperature change and corresponding physical and chemical properties of the sample .
Performance Advantages OF STA Synchronous Thermal Analyzer
The furnace body heating adopts double-row winding of precious metal platinum-rhodium alloy wire to reduce interference and be more resistant to high temperature.
The pallet sensor is made of precious metal alloy wire and has the advantages of high temperature resistance, oxidation resistance and corrosion resistance.
The power supply, circulating heat dissipation part and the main unit are separated to reduce the influence of heat and vibration on the microthermal balance.
The host adopts an isolated heating furnace to prevent the thermal impact of the chassis and microthermal balance.
The furnace body adopts double insulation, which has better linearity; the furnace body has automatic lifting and can cool down quickly; it has an exhaust gas outlet and can be used in conjunction with infrared, etc.
