The DSC Q20 is a Differential Scanning Calorimeter (DSC) developed by TA Instruments, designed for research, teaching, and quality control applications that require a basic yet reliable instrument. This equipment offers calorimetric performance superior to that of many competing research models, standing out for its ease of use and cost-effectiveness.

In terms of its technical specifications, the DSC Q20 operates within a temperature range from ambient to 725 °C, which can be extended from -180 °C to 725 °C with additional cooling accessories. It offers a temperature accuracy of ±0.1 °C and a calorimetric accuracy of ±0.1%. Its sensitivity is 1.0 μW, with a digital resolution exceeding 0.04 μW. The equipment also features dual digital mass flow controllers for precise handling of purge gases.

The Tzero® cell design of the Q20, made of constantan and mounted on a silver heating block, provides rapid signal response, flat and reproducible baselines, and superior sensitivity and resolution. Additionally, the Q20 is compatible with a variety of cooling accessories, such as the Refrigerated Cooling System (RCS) and the Liquid Nitrogen Cooling System (LNCS), which enable DSC and MDSC experiments over a wide temperature range.

En resumen, el DSC Q20 es una herramienta versátil y precisa para el análisis térmico, adecuada para diversas aplicaciones que requieren mediciones calorimétricas fiables y reproducibles.
