Stream Infinity Capabilities
Discover new potential for your in situ experiments.
1) Perform electrochemistry as a function of temperature
The new Stream Infinity holder features eight electrical contacts that enable simultaneous application of electrical and thermal stimuli in a liquid environment. The contacts can be used for various electrically driven MEMS-based sensors and actuators, making the Infinity platform essentially a research playground.

2) Easily switch between STEM and TEM mode
By flipping the tip 180 degrees, you can directly change the sample position to be either on the top or bottom without a need to disassemble the tip. This grants you the freedom to flawlessly switch between STEM or TEM mode, respectively, depending on your experimental needs, while maintaining the best resolution performance. Importantly, you can switch between both imaging modes within a matter of seconds.

3) Securely transfer your sample from one microscope to the other
The universal tip of the Infinity holder works as a cartridge that can be moved from one holder body to another, without disassembling the universal Nano-Cell. This feature enables complementary cross-platform studies of the same sample in SEM, beamline setups or using TEM’s from JEOL or Thermo Fisher Scientific (TFS). These setups can either be located in the same lab, user facility or even in different universities/institutes, allowing for correlating experimental results in different platforms.

4) Perform liquid and gas studies with the same holder
The new environmental Infinity holder is your all-in-one solution for both liquid and gas experiments. Simply choose the appropriate function for the chips and connect the necessary liquid or gas supply system. Our extensive range of chip types includes liquid-heating (LH), gas-heating (GH), liquid-heating-biasing (LHB) and gas-heating-biasing (GHB), offering unparalleled versatility for your experimental needs. New MEMS chip designs can further expand the application space of the Infinity system.

5) High resolution imaging and meaningful analytical analysis
The LSS introduces the capability of controllable and inert gas purging. The purging is done via a separate gas line, allowing you to flawlessly switch between the liquid and inert gas to characterize the sample in between, for example, electrochemical cycling. The switching can be achieved without the air exposure, which is especially beneficial for air-sensitive samples, like Li-ion batteries. Via air/inert gas purging, you can easily get rid of excess liquid in the sample, thereby allowing you to achieve high resolution imaging and to perform meaningful electron diffraction, EELS and EDX studies.

Frequently Asked Questions
Can I safely use the Stream Infinity holder in my TEM?
Yes. The Stream Infinity holder dimensions are designed within the specifications for the applicable objective lens pole piece as provided by the TEM manufacturer (Thermo Fisher Scientific or JEOL). As long as the holder is also used within the Z- and T-axis range specified in the user manual, there should be no risk of the holder touching the pole piece. Before every insertion of the Stream Infinity holder into the TEM goniometer, it is tested for vacuum leaks with a turbomolecular pump. Only after this test is passed successfully, the user can continue to the next step of TEM insertion.
What is the preparation time for a typical experiment?
Preparing the Stream Infinity holder to run an experiment typically takes 20 minutes or less, depending on the user experience:
- 5-10 minutes to assemble the holder: placing the O-rings and the Nano-Cell into the tip and closing off the lid
- 10 minutes to check the leak-tightness of the holder before TEM insertion
This time excludes sample preparation as this can vary from sample to sample.
Can the sample position be changed from the top to the bottom window for optimum STEM or TEM imaging?
Yes. The Stream Infinity holder has a removable and symmetric tip. Once the holder is assembled, the user can choose the orientation of the sample, e.g. on the top or the bottom window by rotating the whole tip by 180 degrees along the holder axis. In the standard configuration, the sample is located on the top window which is optimum for STEM imaging. When the tip is rotated, the sample position is optimum for TEM mode. Notably, flipping the tip is a quick and easy process, taking less than a minute to complete.
How long does it take to replace the liquid tubing?
The Stream holder has individually replaceable tubing and it takes about 5 minutes to replace the tubing. Fused Silica is the standard material of the tubing, but this can be changed for PEEK or another material if required by the user.
Is it possible to perform gas experiments with the Stream Infinity holder?
Yes. The Stream Infinity holder is identical in terms of the design to the Climate Infinity holder and, as such, it can be used in combination with gases. To enable in situ gas heating and/or biasing experiments in the TEM, a Climate Nano-Reactor and a Gas Supply System need to be used in combination with the Stream Infinity holder. To avoid cross-contamination between liquid and gas experiments, it is advised to have a dedicated tip and a set of tubings and O-rings for liquid research.
