MEL-BUILD Double tilt LN2 Atmos Defend Holder

vacuum transfer

High stability is essential for acquiring atomic-scale information by transmission electron microscopy (TEM). This is especially true in the case with materials that are susceptible to beam damage that require cooling to Cryogenic temperatures. The MEL-BUILD Double tilt LN2 Atmos Defend Holder is designed specifically for the material scientist. Ideal for Lithium-Ion Battery research this newly designed Double Tilt LN2 TEM holder incorporates a specially designed vacuum transfer system and a proprietary mechanical drift cancellation controller. This combined with a high precision temperature controller which range is ± 0.005°C allows for stable and repeatable acquisition of data.  In addition, the double tilt mechanism allows the TEM microscopist to match the crystal orientation, making it the only LN2 TEM holder in the world that allows atomic resolution observation.

The above image is an Atomic resolution STEM image of LLZ(Li7La3Zr2O12), From this result, it was proven that the non-exposure (Vacuum Transfer) was successful. The crystal orientation was adjusted by Y tilt, and the electron beam damage was reduced by cooling of -160°C. Cooling and stability was achieved in 60 minutes.
