Nanatom - TRAVIX
Micromechanical In-situ Test Stage
Nanatom’s vacuum compa.ble micromechanical In-situ Test Stage TRAVIX for Scanning electron and optical light microscopes is designed to conduct micro tensile, compression and fatigue tests with high precision. TRAVIX is capable of performing tests on a vide range of materials - metals, alloys, fibres, polymers, plas.cs, ceramics, rubber, biomaterials, etc. The crystalline orientation, the failure of particles as well as the initiation and the propaga.on of cracks can be observed during the test.
In-situ Tests can be performed while observing the sample:
- In a scanning electron microscope (Vacuum)
- Under an Optical light microscope
- As a standalone system
Features
- Once within the SEM’s field-of-view the sample remains centred throughout the experiment
- High resolution strain measurements starting at very low strain rates
- Inline elongation measurement using a high resolution optical encoder system. Eliminates lead screw errors
- In compliance with ASTM standards andspecifications
- DeepSense Test and Analysis soRware provides
- Real time force-displacement plots
- Selectable Data acquisition rates from 10 Hz to 2.5 kHz
- Raw test data and results exportable to excel, csv & pdf
- Built-in Self Calibration tools
- Flexible reporting format
- Deformation and relaxation behaviour can be observed under dynamic or static loading
- Load sensor capacities of 500 N, 1000N, 5000 N and 9000 N
- Quick-connect mounting adapters are provided and designed for seamless integration into most major microscopy tools
- Customised feedthroughs allow users to install systems without modifications to SEM vacuum chambers or microscope plaaorms
- Results are displayed in real time. Stress-strain curves generated while test is in progress as live plots
- Parameters such as peak load/stress, yield points, modulus of elasticity and other measurements reported
- Versatile EtherCAT based controller with multiple ADC and DAC channels for high speed and precise control
