The Excellence Dynamic Mechanical Analyzer DMA 1, introduced by Mettler Toledo at Pittcon 2013, offers six different deformation modes to gauge materials performance. The instrument can handle multiple dynamic and static measurements to characterize viscoelasticity, glass transition, softening, crystallization, and phase transformation, according to the press announcement.
Users can set the sample arm and analysis head at multiple angles based on sample nature and geometry. Rapid cooling to as low as -190 ºC with minimal liquid nitrogen consumption also helps improve sample throughput, reduce costs, and improve operator safety.
The linear variable differential transformer (LVDT) measures changes in length over a measurement range of ±1 mm with a mean resolution of 2 nm. The DMA 1 also offers the ability to operate in liquids or at specific relative humidity levels.
