Abstract

Cryogenic-fixation apparatus comprises a light source, a beam from which enter cooling liquid in a bath, through a window in the underside of the bath. The beam can be directed upwardly by means of a reflecting prism. When a lid of the bath is closed, the beam leaves the space defined by the path through an exit port in the lid, and is incident upon a specimen mounted on a specimen holder located above the exit port, the specimen holder being secured to an injector rod.
