About this instrument

The DMA 850 (Dynamic Mechanical Analyzer) by TA Instruments is a sophisticated analytical instrument used to study the mechanical properties of materials under dynamic conditions. It is particularly useful in the analysis of polymers, elastomers, and other materials that exhibit viscoelastic behavior, providing insights into properties like stiffness, damping, and thermal transitions.

Features & Specifications:

  1. Temperature Range:
  • Standard: -150 °C to 600 °C,
  • Frequency Range:
  • Typically 01 Hz to 200 Hz, allowing for dynamic testing at various frequencies.
    1. Strain Amplitude:
  • 001% to 1% strain range, allowing the user to control the deformation and obtain accurate responses for both linear and non-linear materials.
    1. Force Range: 0.0001 – 18 N
    2. Force Resolution : 10-4N
    3. Strain Resolution : 0.1 nm
    4. Modulus Range: 103– 1012 Pa
    5. Tan delta sensitivity: 0.0001
    6. Tan delta resolution: 0.00001
    7. High Sensitivity:
  • High-resolution measurements for detecting small changes in material properties with precision.
  • Provides detailed data on the viscoelastic response, including damping and phase angle shifts.
    1. Software:
  • TA Universal Analysis™ Software: Comes with advanced software for test setup, data collection, and detailed analysis.
