STA 449 F3 Nevio
Specialized for Demanding Tasks in Research & Development
The simultaneous thermal analyzer NETZSCH STA 449 F3 Nevio allows the measurement of mass changes and thermal effects under identical conditions at the same specimen. Thus it makes it feasible to differentiate between e.g., structural changes and degradation phenomena within just one mesurement up to 675°C1.
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 different kinds of pharmaceuticals, cosmetic samples or food including also inhomogenous substances.
The vacuum-tight design of the instrument is an essential requirement for evolved gas analysis, i.e., the coupling of the thermal anlyzer to a gas analyzing system such as FT-IR, MS or GC-MS.
Various furnaces, easy interchangeable by the user, cover a very broad temperature range (please see accessories).
In addition, due to its modular setup the STA 449 F3 Nevio is also prepared to investigte samples under defined humid atmsophere.
The analysis of measuring data runs under a standard PC and the innovative NETZSCH Proteus software.

The STA 449 F3 Nevio runs under Proteus® Software on Windows®. 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.
Features concerning TGA plus DSC:
- Proteus Protect (option) – meeting the requirements of 21 CFR Part 11 and EU Annex 11
- AutoEvaluation – autonomous and user-independent evaluation of thermal effects
- Identify (option) – curve recognition and database system for library search purpose
- SuperPosition – Simulation of the thermal behavior of physical mixtures by overlapping the curves of the mixture components incl. freely selectable mass ratios
- Average curves – absolute (taking the sample masses of the various measurement s into account) or relative (applies just the number of measurements as denominator)
- Report generator – based on a Microsoft Word plug-in each operator can easily create his own report template for reports – including logos, tables, description fields and plots.
