Latest Patents

Hazenberg's latest patents focus on a method of preparing a cryogenic sample with improved cooling characteristics. This invention relates to a method and an apparatus designed for rapid cooling using a cryogen. The system includes a pair of conduits for transporting cryogenic fluid, each opening into a mouthpiece that faces another across an intervening gap. In this gap, a sample on a substantially planar sample carrier can be placed. The design allows for the concurrent flushing of cryogenic fluid from both mouthpieces, immersing the sample in cryogenic fluid from two opposite sides. Notably, at least one of the mouthpieces features multiple nozzle openings to ensure even cooling of the sample carrier during the flushing process.
