Abstract: The invention relates to a method and an apparatus for preparing a cryogenic sample, whereby the sample is subjected to rapid cooling using a cryogen. A pair of conduits for transporting cryogenic fluid are provided, each of which conduits opens out into a mouthpiece, which mouthpieces are arranged to face each other across an intervening gap, wherein in said gap a sample that is provided on a substantially planar sample carrier can be received. Cryogenic fluid can be pumped through said conduits so as to concurrently flush from said mouthpieces and suddenly immerse the sample in cryogenic fluid from two opposite sides. As defined herein, at least one of said mouthpieces comprises at least two nozzle openings for evenly cooling said substantially planar sample carrier during said flushing.

Abstract: The invention relates to a method and an apparatus for preparing a cryogenic sample, whereby the sample is subjected to rapid cooling using a cryogen. The method comprises the step of providing a sample, said sample comprising a specimen provided on a substantially planar specimen carrier. The method comprises the step of providing at least one flow device for transporting cryogenic fluid to said sample, wherein said flow device comprises a first nozzle for directing a flow of cryogenic fluid onto said sample. Then, the sample is positioned next to said first nozzle and a flow of cryogenic fluid is provided out of said first nozzle in such a way that the sample is cryogenically cooled. As defined herein, the nozzle opening of the first nozzle has a width, as measured in a first direction, and a height, as measured in a second direction substantially perpendicular to said first direction, wherein said width is larger than said height.
