Overview
The Mel-Build DCT holder is a double tilt LN2 cooling vacuum transfer holder for cryogenic TEM observation. It provides guaranteed cooling to -155 °C with vacuum transfer capability, enabling damage-free analysis of beam-sensitive and air-sensitive materials such as solid electrolytes, perovskites, and biological specimens.
Key Features
- Double tilt at cryo temperature: X tilt ±30°, Y tilt ±20° at standard pole piece
- Vacuum transfer: Keeps specimens under vacuum (<1×10⁻³ Pa) during loading
- High resolution: Atomic-resolution imaging confirmed at cryogenic temperatures (0.24 nm)
- Temperature controller (MTC-002): Stability ±0.005 °C
Applications
- Air-sensitive battery materials (solid electrolytes, Li metal)
- Beam-sensitive materials (perovskites, polymers)
- Cryo-STEM/EDS at low temperatures
