Liquid helium cryo-TEM

A newly developed cryo-TEM sample holder for experiments at liquid helium temperatures with heating and electrical biasing capabilities. Standard 3mm grids can be fixed on a sample chip and then slipped into the sample holder. Mechanical stability is enabled by a damping stage counteracting vibrations from the ground and helium flow through a low-noise helium transfer line.


Base temperature 5 K
Cool-down time < 5 min
