The simultaneous thermal analyzer NETZSCH STA 449 F3 Jupiter® allows the measurement of mass changes and thermal effects between -150°C and 2400°C.
The high flexibility caused by the various sensors, the great variety of sample crucibles and the wide TGA-measuring range make the system applicable for analysis of all kinds of materials including also inhomogenous substances.
Easily interchangeable sample holders allow the optimal system adaption to the diverse application areas (TGA, TGA-DTA and TGA-DSC measurements).
Various furnaces, easy interchangeable by the user, cover the complete temperature range (please see accessories).
Through to the vacuum tight design measurements at defined atmospheres (e.g. inert) are possible. The system is controlled by a newly developed integrated digital electronic device.
The analysis of measuring data runs under a standard PC and the well-proven Windows® software.

The STA 449 F3 Jupiter® runs under Proteus® Software on Windows® XP and Vista®. The Proteus® Software includes everything you need to carry out a measurement and evaluate the resulting data. Through the combination of easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly and, at the same time, allows sophisticated analysis. The Proteus® software is licensed with the instrument and can of course be installed on other computer systems.

- TM-DSC module software extension for temperature-modulated DSC tests (optional)
A variety of sample crucibles (pans) made of alumina, platinum, aluminum, graphite, fused silica, etc. is available in different sizes.
The water vapor furnace with perfectly balanced accessories for steam generation, gas mixing and flow control offers the unique opportunity to study the mass and energy changes in samples up to 1250°C under defined absolute humidity.
The high-speed furnace does not require a stand-alone instrument but extends the well-established instrument series STA-Jupiter® by another furnace type. The concept allows for equipping a measuring instrument with a double-furnace hoisting device for two furnaces. The high-speed furnace can therefore be mounted on the double hoisting device combined with other furnaces. Instead of a second furnace, an automatic sample changer (ASC) can optionally be used for the high-speed furnace. Modular flexibility and particularly the combinability of the high-speed furnace with the ASC saves a great amount of time and thus directly results in an increased sample throughput.
Optionally available, the OTS® system allows for reducing effectively the oxygen partial pressure at the sample vicinity.
The automatic sample changer is designed for routine measurements. It works day and night, giving you time for other tasks, and provides for optimal use of the STA 449 F3 Jupiter® (e.g. calibrations on the weekend).
A carousel is available for up to 20 sample and reference crucibles (pans) which can be automatically run in any order. The controlled generation of the required gas atmosphere in the sample chamber and cooling are automatic.
Of course, each sample can be assigned an individual measurement and evaluation macro. Easy-to-understand input masks lead you through the programming of the measurement series. And it is always possible to insert unplanned analyses into a preprogrammed series of measurements that is already in progress.
With the PulseTA® technique an exactly defined quantity of gas is injected to the purge gas of the thermobalance (TGA) or the simultaneous thermal analysis instrument (STA).
This clearly increases the measuring possibilities:
- Defined/incremental chemical reactions or adsorption of the injection gas with the sample
- Quantification of gases evolved from the sample.
