Abstract: In a light microscope (1) for cryomicroscopy, encompassing at least an objective (2) and a sample stage (3) having a cutout (7) for a coolable holder (8) for a sample carrier mount, the cutout (7) being covered by a cover (6), the sample stage (3) is displaceable in two horizontal directions (4). The cover (6) rests floatingly on the sample stage (3), and the objective (2) passes through a cutout (12), corresponding to the objective (2), in the cover (6). The method for cooling a holder (8) for a sample carrier mount in a light microscope (1) for cryomicroscopes, by means of a flow of liquid nitrogen through a cooling conduit (15), open at at least one end, in the holder (8), is notable for the fact that the quantity of liquid nitrogen is dimensioned so that all of the nitrogen is present in gaseous form at at least one open end (16) of the cooling conduit (15).

Abstract: A loading station (100, 200) for translocating a frozen sample for electron microscopy, encompassing a chamber (104, 204), open toward the top, that is fillable at least partly with a coolant, the chamber (104, 204) comprising in its side wall at least two ports (101a, 102a, 103a) each for different sample transfer devices (101, 102, 103), the ports (101a, 102a, 103a) permitting introduction of a frozen sample into the chamber (104, 204) via a selected sample transfer device and withdrawal of a frozen sample from the chamber via a respective different sample transfer device; and wherein a receptacle (108, 208) for at least two differently configured sample holders (109, 110) is arranged in the chamber (104, 204), the at least two sample holders (109, 110) being detachably fastenable to at least one of the sample transfer devices (101) for introduction of the frozen sample into the chamber (104, 204) and for withdrawal of the frozen sample from the chamber (104, 204).

Abstract: In a manipulation container (1) for cryomicroscopy, having at least one holder (9) for a sample carrier mount (7) and at least one manipulation opening (2) for manipulating sample carriers or sample carrier mounts (7), the holder (9) for a sample carrier mount (7) is movable into a displacement path (11), passing completely through the manipulation container (1), of a displacement apparatus (3) for the sample carrier mount (7).
