LABSYS evo STA (simultaneous thermal analysis)

The highlights

TGA, and Simultaneous TGA-DTA, TGA-DSC from ambient to 1150°C or 1600°C

LABSYS evo is a user friendly, robust and highly powerful thermal analysis platform.

• A comprehensive line of thermal analyzers with two temperature ranges chosen and optimized for distinct families of application:
– RT – 1 150 °C, a cost effective solution mostly (but not only) for organic materials studies (polymers, pharmaceuticals, petroleum by-products…),
– RT – 1 600 °C, for demanding high temperature experiments involving mostly (but not only) inorganic materials like ceramics or metals.
• A top loading balance designed specifically for thermal analysis applications featuring unmatched stability, reproducibility and accuracy.
• Plug & play TGA, DTA, DSC and CP rods for the best Simultaneous Thermal Analysis experience users can get.
• A 30 samples / 6 references autosampler able to automatically configure to the different sensors and crucibles.

Controlled vacuum option
This option allows for operation under controlled vacuum. One can manually set a controlled pressure down to 30 mbar. Evolved gas analysis by MS coupling is possible at the same time.

Quartz crucibles
DSC or DTA crucibles made of quartz are available.  The crucible’s volume is 100 µl, diameter 5 mm and height 8 mm.

Large volume crucible
A large volume 1000 µl (1 ml) alumina crucible, diameter 8mm and height 27 mm, is available for TGA experiments.

Ampoules for Cp rod
Sealable glass ampoules are available with the LABSYS evo 3D Cp rod. They are used for DSC measurements only, and their approximate volume is 125 µl.

SIMULTANEOUS THERMAL ANALYSIS (TG-DTA or TG-DSC) additionally allows qualifying or quantifying the heat effects occurring during a mass variation or any transition not related to a mass change.
The different LABSYS evo STA rods (DTA, DSC, 3D CP) are changed within seconds using our unique “plug & play” connector and the automatic identification system of the rod type.

DTA is available with 80, 90 or 100 μl crucibles made of aluminum, alumina or platinum
Plate type DSC is available with 80, 90 or 100 μl crucibles made of aluminum, alumina or platinum.

LABSYS evo offers a “Plug & play” gas analyzer coupling device,enabling simultaneous MS and FTIR connections. The coupling device is heated up to 300 °C to avoid any gas condensation and is complete ly insulated for a safe handling.

A NEW auto sampler system is available for Labsys evo TGA, TGA-DSC, TGA-DTA providing 30 samples and 6 references possibilities.


LABSYS evo STA 1150 applies mostly to organic materials when a more in-depth understanding of their thermal behavior is necessary. Identifying the thermal phenomena is made easier thanks to the DTA or DSC signals. Transitions like melting, crystallization, glass transition and solid-solid transitions, or reactions like curing and oxidation (OIT: oxygen induction time) can then be characterized together
with the phenomena involving mass variations.
LABSYS evo STA 1150 is also an ideal tool to screen thermal hazards linked with energetic materials.

LABSYS evo STA 1600 is the ultimate solution when temperatures as high as 1600 °C are concerned. It is the perfect tool to understand the thermal behavior of materials that are exposed to extreme temperatures during their production, service, or recycling. There are numerous examples but one can
cite the determination of the sintering temperatures of metal powders, the determination of the thermal characteristics and ageing of refractory materials or the incineration of industrial wastes.
The LABSYS evo STA 1600 can also be used with the 3D CP rod which, on top of heat capacity measurements, allows for accurate quantification of heat transition effects.
