[/custom_headline][text_output]

The Alemnis Nanoindenter is a compact and flexible instrument ideally suited for true in-situ nanome- chanical testing of a variety of materials in different applications as it can be easily integrated with nu- merous imaging equipment. Highly accurate and precise due to its unique displacement control mode, the Alemnis Nanoindenter is specifically designed for testing under high frequency or extreme tem- perature conditions with one of the most attractive price-performance ratios on the market.

Description

TRUE DISPLACEMENT MODE

Unique primary mode of operation: displacement controlled enabling strain rate jump, stress relaxa- tion and fracture tests – operator can freely define indentation profiles (displacement or load control)

USE IN AIR (Standalone) AND IN SEM

Maximum versatility for use as a Standalone indenter or in Scanning Electron Microscopes (SEM). Can also be used with HR EBSD (subject to certain conditions), micro-Raman, x-rays at synchrotron beam- lines and with many more techniques

COMPACT AND FLEXIBLE

Compact size of 16 cm x 6.5 cm x 4.6 cm which can fit inside majority of testing and imaging instru- ments. One of the most stable and flexible instruments in the market

ACCURACY AND PRECISION

Large force range (0.5N, optional 2.5N), high positioning accuracy, accurate-tip-to-sample alignment (1 nm resolution) and extremely high mechanical stability (thermal drift of 5 nm/min or less) for long term experiments.

MODULAR DESIGN AND EASY HANDLING

Short set-up times, portability for use in different set-ups and instruments, fully modular design for testing in high frequency or extreme temperature conditions.

CUSTOMIZABLE SOFTWARE (AMICS))

Customizable control software allowing maximum flexibility in test design and set-up.

ANALYSIS SOFTWARE (AMMDA)

Allows the users to make data corrections as well as data analysis on acquired datasets from AMICS software.

COST EFFECTIVE

Attractive price-performance ratio compared to existing products on the market.

Ultra-High Strain Rate Module

The unique and patented Alemnis Ultra-High Strain Rate module allows for controlled strain rates of up to 3’000 s-1 or even 20’000 s-1 under specific conditions.

High Temperature Module

The High Temperature module allows for experiments up to 800°C. Tip and sample temperatures are controlled separately and both temperature are perfectly matched to avoid any thermal drift (<10 nm/min at 800°C). Its modular and robust design allows exchanging the heaters and the tips easily by customer. All tip shapes and different tip materials available .
