TA's Rheometer DHR-2 Comes into use

Date:2017-06-09

The recently bought Discovery Hybrid Rheometer (DHR)-2 from TA Instruments has arrived and been installed in our group in August of 2012. The DHR-2 Rheometer,the upgrade product of AR series, uses the latest Stress-Controlled technology. After debugging., the instrument can normally come into use

The test system of DhR-2 Rheometer including following part:

      (1). Environmental Test Chamber, ETC, including 25 diameter parallel plate (25mm), nitrogen atmosphere system, and self-pressured liquid nitrogen refrigeration system. With the help of attachment, the rheometer can carry out inert gas environment experiments and rapid heating - cooling experiments. Temperature range is -160 to 600 °C with heating rates up to 60 °C/min, providing fast response and temperature stability.

      (2). Peltier Plate assembled 40 mm diameter Cone – plate. It can handle the widest range of material applications with standard, stepped and disposable models. Temperature range is -40°C to 200°C with controllable heating rates of up to 20°C/min. Peltier Plate accessories include evaporation blocking, thermal covers, purge covers, and immersion capability. In order to make better use of the instruments, and to get superior results, the instrument operation training will be held regularly. The operator can only work on his post after qualified training.

Preferentially, tests are available for the members of the group. We believe improved condition will greatly benefit us and promote the research work here.
