Unique modular design:
The Alemnis Standard Assembly (ASA) is a modular indentation platform designed to be customized for your specific needs. Its unique modular design makes it the world’s most versatile, high performance and cost effective instrument and it is used in some of the most prestigious universities and research centers in the world.
A major milestone in the scientific community:
It is based on years of experience in the design of scientific instruments and piezoelectric transducers conducted in joint projects between EPFL (Swiss Federal Institute of Technology, Lausanne) and Empa (Swiss Federal Laboratories of Material Science and Technology, Thun). A publication by the inventors was awarded the Bunshah Award 2004 of the American Vacuum Society. It is considered as a major milestone in the scientific community.
Main Components:
- Displacement head: piezo actuated displacement head with integrated displacement sensor for closed loop operation. Maximum displacement 40 µm, displacement resolution < 1 nm;
- Load sensor: max. force: 0.5 N, typically 4 µN RMS noise;
- Sample versus indentation tip positioning: Piezoelectric XY+Z micro-positioning system for sample positioning and tip approach (26 mm range in X and Y, 26 mm range in Z), with integrated position sensors for closed loop operation (< 2 nm resolution);
- 5 standard stubs;
- all cables and connectors for in air operation.
For integration in SEM, additional modifications may be required, such as custom flanges, cabling, mounts and connectors. This is typically quoted on a case-by-case basis.
Thanks to its unique modular design, the ASA can be used in a variety of configurations:
- in-situ
- ex-situ (as a standalone instrument)
- in synchrotron
- Micro CT (Tomography)
The unique performances of ASA’s true displacement mode is the key to understanding:
- Load drops
- Compression artefacts
- Strain rate jumps
- Sudden load excursions in real time
Widest load range on the market: From µN up to 2.5 N
The ASA enables the testing of materials in a vast array of environments with options including:
Thanks to its unmatched versatility, te ASA is the go-to instrument for researchers in many domains:
The ASA is modular, robust, easy to install and simple to use with its intuitive software.
