TT DMA PRODUCT SPECIFICATION

- Detachable Dynamic Measuring Head
Allows system to be used in any orientation or
configured with other analytical instrumentation
e.g. FTIR, optical devices or X-ray equipment
- -190°C to 600°C standard temperature range
- Controlled heating & cooling* Isothermal operation
-0.1 to 20°C/minute
- Dramatic cooling capability*
Only 1 litre of LN2 is required to cool the DMA to -100°C six times from one charge
Each cooling cycle taking less than 3 minutes
-190°C takes just 7 minutes and uses well below 1 litre of LN2
*requires optional 1 litre or 10 litre cryo accessory
- 10-3 to 103 Hz frequency range (sample dependant), with 1mHz resolution
- Frequencies or Strain (isothermal operation) – number per experiment unlimited
Selected by number of frequencies per decade in either log or linear mode
- Titanium clamp parts
Low mass and rugged, resulting in improved heating/ cooling performance
- Standard Geometries
| Geometry | Max Dimensions | Free Length | Defined | +Unlimited |
| Single Cantilever | 28mm x 13mm | 1mm - 17.5mm2 | 18 | Yes |
| Dual Cantilever | 55mm x 13mm | 1mm - 17.5mm2 | 18 | Yes |
| 3 Point Bending | 55mm x 13mm | 20mm - 45mm2 | 6 | Yes |
| Tension | 30mm x 13mm | 0 - 20mm | 7 | Yes |
| Compression | 10mm x 12mm | 0 - 12mm | - | Yes |
- Improved drive train
No stepper motor, low compliance, no air bearing and high reliability electronics, results in reduced
maintenance. The Lowest drive mass of any DMA means reduced inertia, which significantly improves high
frequency measurements
- Stiffness Range 2 x 10 to 1 x 108 N/m
- Modulus Range 103 to 1016 Pa (theoretical)
- Modulus resolution 0.0001 Pa
- Tan δ resolution 0.00001
- Displacement resolution 10nm
- Displacement (Strain) Range 0 to +/- 1mm (sample permitting)
- Force
| Range | ±10N |
| Minimum | 0.00025N |
| Resolution | 0.00025N |
- Colour LCD touch screen with clear instrument status display
- Instrument pre calibrated
No day to day calibration required. Instant operation on ‘switch on’.
Annual calibration checks are sufficient for most users.
- Triton Laboratory© Multitasking Software platform
Allows any other Triton Laboratory product to be multi-tasked on same PC.
Simultaneous operation of Humidity and Immersion accessories.
Software compatible with Microsoft™ Vista or XP.
Purge Gas via 6mm Ports.
Cryogenic Liquid via 6mm Ports.
- Optional optical windows and ports available. Note that temperature range may be compromised with
certain configurations
- Optional Humidity accessory available allowing measurement of materials up to 85°C to 85% RH at lower
temperatures
- Optional Immersion accessory available for testing materials in non flammable liquids - available for all
geometries
- Optional 1 litre cryo. For manual cooling to start temperature. Note that this unit capable of providing limited
controlled cooling or heating.
Typical cooling performance with I litre Cryo:
Ambient (25°C) to -100°C takes less than 3 minutes and uses less than 200ml of LN2
I litre of LN2 can typically cool down from Ambient to -100°C six times from one filling.
Ambient to -190°C typically takes 7 minutes.
- Optional 10 litre auto cryo configuration. For controlled cooling or heating or isothermal sub ambient
operation.
- Optional Powder pockets. Allows powdered materials to be examined
- Optional Sealable Liquids holders. Good for studying powdered materials to be examined
- Optional identiPol as Sample Preparation Rig for thermoplastic pellets. Requires following 2 items as
well;
- Optional identiPol Clamp for holding identiPol sample holders described below
- Optional patented metal sample holder for thermoplastic samples, enabling fast and accurate temperature
scans (20°C/min)
Polymer granules are melted into the holder and can then be analysed in the DMA. Requires optional
identiPol
