Mettler Toledo has announced the launch of its latest Excellence Dynamic Mechanical Analyser DMA 1.
The analyser offers six different deformation modes to more accurately gauge materials performance.
The DMA 1 serves as one piece of equipment able to handle multiple dynamic and static measurements to characterise viscoelasticity, glass transition, softening, crystallisation and phase transformation.
According to the company, it is ideal for both academic and manufacturing labs.
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 also helps improve sample throughput, reduce costs, and improve operator safety.
A high-end temperature range of 600 ?C further increases the DMA 1 application range.
A key feature of the DMA 1 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.
Further enhancing its flexibility, the DMA 1 also 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.
Features and benefits overview:
- Flexible positioning of the measuring head
- Easy operation - allows fast change of deformation modes
- TMA measurements - for measuring expansion coefficients, effects due to creep, and relaxation times
- Humidity option - for sorption and desorption measurements
- Ergonomic design with large touchscreen - for convenient sample loading and monitoring of the measurement process
- Wide temperature range - from -190 °C to 600 °C
- Efficient and economical cooling - saves valuable measurement time and reduces liquid nitrogen consumption
