摘要： Freezing apparatus is described particularly useful for producing frozen pellets of a medium containing spermatozoa, for use in artificial insemination. The apparatus includes a freezing chamber having a heat-conductive removable freezing plate constituting the top wall of a compartment into which a cooling gas is fed from a liquified gas container. A valve in the gas feed line controls the amount of gas fed to the freezing chamber to produce a preselected temperature as preset by a controller, and an electrical heating element within the liquified gas container effects the drive of the gas from the container to the freezing chamber. The heat-conductive plate is formed with a plurality of recessed pockets in which the medium is introduced and freezes in the form of pellets.
