Elsa Cryo-Transfer Holder
Transfer cryo-EM samples to your TEM frost-free
The Gatan Elsa is a next generation cryo-transfer holder. A single-tilt liquid nitrogen holder for transferring samples frost-free at liquid nitrogen temperature to your microscope.
Designed for imaging radiation-sensitive, frozen-hydrated specimens with cryo-EM (single particle cryo-electron microscopy).
- Large dewar for increased liquid nitrogen volume
- Longer experiments
- >9 hours hold time below -145°C
- >8 hours of stable, high-resolution imaging
- High quality imaging with <1.5 nm/min drift rate
- High resolution cryo imaging – Resolve <2.3 Å features
- Reduced settling and drift during tomography, with a centrosymmetric design to balance the centre of gravity during stage tilts
