Additional Modular Details
Gas Supply Systems
By integrating all control functions into a single platform with a small and mobile footprint, managing your in situ TEM experiment becomes a breeze. Programmed by Impulse Software, the user has full control over reproducible experiments via an intuitive user interface.
- Ultra-fast flow control unit
Change gas conditions in the sample area takes less than 15 seconds. - Twin pressure controllers
Perform experiments at equal pressure and different flow rates or at equal flow rates and varied pressures. - Patent-protected mixing valve
This innovation eliminates the need for a mixing tank and makes changing the gas composition within the Nano-Reactor happen within seconds. - Dynamic mixing up to three gasses
The Gas Supply System can mount up to three 10-L gas cylinders that are connected to inlets attached to calibrated mass flow controllers.
Modular Sample Holder
The Climate in situ sample holder provides a platform for connecting the Gas Supply System to the sealed Nano-Reactor inside the vacuum of the TEM. Fabricated with the highest precision techniques, the holder will fit seamlessly into the microscope’s goniometer.
Alpha tilt range depends on system. Up to ± 21° (depending on polepiece) with JEOL and up to ± 35° (depending on polepiece) with Thermo Fisher Scientific.
- Exchangeable tubing & removable tip
A modular design allows each component to be cleaned or replaced, ensuring each new experiment is free from cross-contamination.
- Mechanical stability
Achieve atomic resolution in TEM and STEM in static and flow modes. Achieve a drift rate lower than 0.5 nm/min depending on microscope configuration.
- Upgrade benefits
Easily upgrade to the latest generation components, ensuring your research is always at the forefront of what is possible with in situ TEM.
Gas Analyzer
The Gas Analyzer is designed to work seamlessly with the Climate system to enable real time analysis of reaction products and transforming your experiment into an operando TEM workflow.
