The easy-to-use and cost-effective thermo-microbalance
The thermo-microbalance, TG 209 F3 Tarsus®, represents a cost-effective overall concept, tailored not only to the quality assurance of polymers, but also to routine applications in the fields of organic, chemistry, pharmaceuticals, cosmetics and food.
This basic instrument for thermogravimetric measurements offers already a resolution of 0.1 µg. The TG 209 F3 Tarsus®operates between room temperature and 1000°C with freely selectable heating rates from 0.001 K/min up to 200 K/min. The accurate sample temperature is detected by a thermocouple in direct contact with the sample crucible. Through the reliable vertical construction with sample carrier lift, the thermo-balance as a top-loader, is easy and safe to use, with no hang-down wires or exposed fragile parts.
The calculated DTA-signal c-DTA® (option) not only is ideal for temperature calibration. During sample measurements it yields important information regarding endothermal processes (e.g. vaporization with mass loss or melting without mass loss) as well as exothermal reactions.
For the TG 209 F3 Tarsus® we offer an automatic sample changer (ASC) for up to 20 samples also in different crucible types.

Software
The TG 209 F3 Tarsus® runs under Proteus® Software on Windows®. 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.
