The STA 449 C Jupiter® is number one among thermo-microbalance based simultaneous TG-DSC because of the match-up of a vacuum-tight instrument design with the successful combination of the highest TG/DSC resolution and unsurpassed long-term stability.
Flexibility for all applications involving organic and inorganic samples is achieved with four exchangeable furnaces for the broad temperature range of -120°C to 1650°C and with a multitude of sample carriers and crucibles.
The vertical design and top-loaded samples ensure total protection of the digital ultra-microbalance, which is on the bottom, through accurate flow of the purge and protective gases in a natural vertical path to the top. This also provides optimal conditions for coupling FTIR and MS gas analysis systems to the heated furnace outlet. The mass flow controllers for 3 gases are already integrated into the base instrument.
The TG sample carriers are always equipped with a thermocouple for direct measurement of the temperature at the sample crucible. There are a number of different thermocouple types to choose from, depending on the application.
Unique is the isolation of the sample carrier from the balance upon automatic opening of the furnace to load a sample. This guarantees reliable mechanical protection of the high-resolution ultra-microbalance and thus a long service life.
From the outset, the STA 449 C Jupiter® was designed for both simultaneous TG and true DSC as well as simultaneous TG with quantitative DTA. The TG sample carriers are user-exchangeable within a matter of seconds, so it is possible to switch between TG and TG-DSC, TG-DSC-Cp or TG-DTA measurements at any time, always with superlative performance.
The STA 449 C Jupiter® is the most powerful and versatile STA system for research and development as well as all material characterization problems for the entire range of organic and inorganic materials.
