Patent number: 12270602Abstract: 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 the gap a sample that is provided on a substantially planar sample carrier can be received. Cryogenic fluid can be pumped through the conduits so as to concurrently flush from the mouthpieces and suddenly immerse the sample in cryogenic fluid from two opposite sides. As defined herein, at least one of the mouthpieces comprises at least two nozzle openings for evenly cooling the substantially planar sample carrier during the flushing.Type: GrantFiled: April 23, 2024Date of Patent: April 8, 2025Assignee: FEI CompanyInventors: Maarten Kuijper, Hervé Remigy, Mathijs Petrus Wilhelmus Van Den Boogaard, Adrian Koh, Ivanka Spee, John Hazenberg, Marius Van Der Does
