STA PT 1600 (TG-DSC)
Simultaneous Thermogravimetry and Differential Scanning Calorimetry (TG – DSC) – High Pressure ability
Description
On point
The STA PT 1600 stands as LINSEIS’ top-tier Simultaneous Thermobalance, combining both TG (Thermogravimetry) and DSC (Differential Scanning Calorimetry) capabilities. This system excels in offering exceptional resolution for TG and DSC measurements, along with the highest vacuum performance and outstanding TG drift stability.
The TG-DSC system is designed with modularity in mind, featuring a range of interchangeable furnaces covering a broad temperature range from -150°C up to 2400°C. It also offers various measuring systems and crucibles to suit diverse applications. Coupled with its compatibility with multiple accessories and optional add-ons, the STA PT 1600 ensures a tailored setup for every specific use case.
Furthermore, three balance versions are available, each distinguished by its maximum sample mass (ranging from 5 to 50 grams) and resolution (varying from 0.025 to 0.1 micrograms). These options provide flexibility in selecting the most suitable balance for different analytical needs.
Benefits of the vertical top loading design of the STA
The LINSEIS TG-DSC features a vertical design with the “sample on top” configuration, which offers the highest level of accuracy thanks to the stable positioning of the sample and ease of sample handling.
Advantages of the Vertical System (Sample on Top) – LINSEIS Configuration:
– Simplicity in sample handling, facilitating the experimental process.
– Convenient exchange of sample holders for versatility in testing.
– Ensured stability of the sample within the furnace, a critical factor for achieving accurate DTA (Differential Thermal Analysis), DSC (Differential Scanning Calorimetry), and Cp (specific heat capacity) results.
However, it’s important to note that this configuration, while advantageous, does involve a more intricate construction compared to other designs, which can be considered a drawback.
