This holder is designed to mount two industry standard pucks, side-by-side, to allow for specimen-transfer and hands-free handling, without breaking vacuum.

The holder is designed for FEI Hydra systems, and provides a cryogenic puck holder for dual-SEM/FIB analysis. This allows for up to two APT pucks for sample holding & mounting within the SEM chamber, allowing for air-free lift from one sample holder to another. This is particularly useful in conjunction with vacuum transfer suitcases, when two pucks may need to be exchanged without venting the SEM chamber.

Originally designed for FEI Hydra FIB/SEMs with cryogenic stages, but can be adjusted to suit local SEM/FIB systems, such as FEI/hydra UMB stage mounts.
