Thermogravimetric Analyzer

  • Thermogravimetric analysis is used for the investigation of physical properties of compounds such as sample volatility, moisture content, oxidation stability, decomposition temperature and flammability studies. It measures the changes in weight in relation to change in temperature extremely precisely and accurately. Scanning rates from 0.1 to 200°C/min Temperature range 15°C to 1000°C.

Isothermal Titration Calorimeter

  • Used for measuring biomolecular interactions, ITC simultaneously determines all binding parameters (n, K, H and S) in a single experiment. The TA Instruments Nano ITC is focused on the measurement of ligand binding and reaction kinetics, with increased baseline stability and more tolerance to environment temperature fluctuations. Nano ITC uses a differential power compensation design for maximum sensitivity and responsiveness. The effective cell volume of the gold cells is 190 L. It is capable of both batch/incremental titration in the temperature range 2 – 800C. The injection syringe has a capacity of 50 L and a stirring rate of 150 – 400 rpm.
