Anton Paar: Environmental Chamber
September 10, 2003
A new environmental chamber from Anton Paar enables rheological measurements from -100 degrees C to 1,000 degrees C, and is available as an accessory for all Physica MCR rheometers. The CTD-1000 can accommodate plate-plate and cone and plate geometries up to 25 mm in diameter, and torsion tools will be available soon. The design of the new chamber includes a ball bearing rail system for safely separating the oven halves, and provides ample space for simple and safe sample loading or tool exchange. High operating temperatures inside the measuring chamber require powerful cooling systems outside. An ingenious cooling circuit keeps the surfaces of the CTD-1000 cool enough to touch, even when aluminum melts are tested in the measuring chamber only a few centimeters away. Applications for the new system include metallic melts such as aluminum, magnesium for automobiles, and housings for laptop computers and mobile phones. Glasses and ceramics can be studied, and structure transitions below the melting point can be analyzed.
