Mettler Toledo Excellence DMA 1 dynamic mechanical analyser

Tuesday, 18 December, 2012 | Supplied by: Mettler-Toledo Ltd

Mettler Toledo has launched its latest Excellence dynamic mechanical analyser, DMA 1. The highly flexible analyser offers six different deformation modes to more accurately gauge materials performance. As one piece of equipment is able to handle multiple dynamic and static measurements to characterise viscoelasticity, glass transition, softening, crystallisation, phase transformation and more, the product is suitable for both academic and manufacturing labs that handle many different types of materials under tight time constraints.

Ease of use has been considered in every aspect of the product. Researchers can set the sample arm and analysis head at multiple angles based on sample nature and geometry. Simple adjustment of the sample arm - without having to calibrate in between configurations - means samples of many shapes and sizes can be processed in quick succession. Rapid cooling to as low as -190°C with minimal liquid nitrogen consumption helps improve sample throughput, reduce costs and improve operator safety. A high-end temperature range of 600°C further increases the product’s application range.

A key feature of the analyser is its linear variable differential transformer (LVDT), which measures changes in length over a measurement range of ±1 mm with a mean resolution of 2 nm. Fitted near the sample to minimise influence of measuring system deformation, this resolution improves the accuracy of time lag/phase shift measurement between the force and displacement to help manufacturers more precisely determine how a particular material will behave in its manufactured context for better performance and reduced rework.

The product offers the critical ability to operate in liquids or at specific relative humidity levels. A humidity chamber/generator and circulating heat bath allow measurements under optimum conditions in every deformation mode.
