  » DMA50
A desktop DMA offering a high force range and outstanding flexibility from glass transition determination to immersed tests, which makes it a thermomechanical testing platform.
High force: 50N (peak)
Broad frequency range: from 1E-5Hz to 200 Hz
Temperature range: from -150°C to 600°C
Analysis of specimens with sizes representative of the material
High performance of the auto-tension mode (coupled static/dynamic control) for film and 3 points bending modes
Multi-purpose thermal chamber
Reversible frame
Possible immersed tests for all stress modes at no extra cost
Simple to use

» DMA+ (100, 150 or 450)  
The DMA+ range has a very rigid frame that exhibits ranges of measurable stiffness and frequency that are unrivalled on the market. The range of available specimen holders, along with » DYNATEST and MULTIDYN analysis software programs, make it a new type of universal electrodynamic testing machine that goes beyond classic DMA products
Very rigid mechanical frame (more than servo-hydraulic machines)
High force: 100N, 150N or 450N (peak)
Unique stiffness range: up to 7 decades can be used in a single test
Unique frequency domain: from 1E-5Hz to 1000 Hz
High measurement precision
Analysis of specimens with material –representative size
Thermal chamber with high heating rate
Displacement stroke up to 12mm or 6mm for creep and stress relaxation tests
Broad selection of specimen holders for multiple geometries and dimensions
Easily upgradeable to meet specific analytical requirements

  » ROB 100
ROB 100 is an automatic specimen loader, which turns each DMA+ to a robotized Dynamic Mechanical Analyzer.
The analysis of a large number of specimens is then possible continuously and autonomously, without any action from the operator during the tests.
ROB 100 offers a free choice in the definition of tests and the combination of experiments applied to each specimen.
Based on an original mechanical system (01dB-Metravib patent), ROB100 ensures the mastery of mounting conditions of each specimen and guarantees unique measurement reproducibility.
ROB 100 allows optimizing the laboratory's productivity in meeting the requirements of industrials who have to analyze large number of formulations of materials.

» VHF 104  
VHF 104 is an innovative Dynamic Mechanical Analyzer that offers a direct experimental method to measure the materials' viscoelastic properties over a very high frequencies range from 100 Hz up to 10 kHz.
Such a test requires only a few minutes, while traditional approach using DMA low frequency test on several temperature stages, requires a few hours test and a calculation through WLF law.
VHF 104 allows optimizing the laboratory's productivity in meeting the requirements of industrials who wish to rapidly analyze large number of formulations of materials.

Main assets :
High frequency range: 100 Hz up to 10 kHz
Temperature range: -50°C up to 110°C
Strain range: up to 30%
Tension-compression mode
Shear mode
Short test duration (about 5 minutes)

Main uses:
Elastomer high frequency testing
Porous materials acoustic properties
