Abstract: A method for hyper-fast cooling of samples is described. The samples are secured in a sample container, then the sample container inserted into a cryogenic cooling chamber through an opening of the cooling chamber. The sample container is placed some distance away from a cooling head, but within range of a continuous stream of pressurized liquid coolant emitted by the cooling head, where, the sample is hyper-cooled by spraying the sample container with a continuous stream of the pressurized liquid coolant.

Abstract: A method for fast cooling of samples comprises: pressurizing a liquid coolant source; securing a sample in a sample container; securing the sample container onto an insertion mechanism; with the insertion mechanism outside a cryogenic cooling chamber, inserting the sample container into the cryogenic cooling chamber through an opening of the cooling chamber; locking the insertion mechanism and securing the sample container in place some distance away from a cooling head, but within range of a continuous stream of pressurized liquid coolant; cooling the sample by spraying the sample container with a continuous stream of pressurized liquid coolant; and retrieving the sample container after cooling.
