Description
The LINSEIS TGA L81 top-loading high-temperature thermobalance consists of a digital balance and a sample holder with integrated thermocouple.
- The thermobalance enables the measurement of samples with a weight of 5 or 25 g (including measuring system).
- Flexibility for all samples is ensured by interchangeable oven types (optional turntable for multiple ovens) for the wide temperature range from -150°C to 2400°C.
- Optional MS and/or FTIR coupling is possible at any time.
The optional, calculated DTA provides additional information on endothermic and exothermic reactions and can be used for temperature calibration.
