A cassette system for systematic cryostorage of low‐temperature scanning electron microscopy stubs

SUMMARY A system is described for the storage of cylindrical (10 × 3.5 mm) stubs for low-temperature scanning electron microscopy. The system facilitates rapid retrieval of mounted specimens, maximizes the capacity of the low-temperature (liquid nitrogen) specimen store, locates each stub exactly in a protected well, and eliminates the possibility of specimen damage from conventional hazards during transport between the storage facility and microscope.
