RECOVERY ASSEMBLY FOR CRYOPRESERVATION APPLICATIONS

摘要

The present invention relates to a recovery assembly for reducing losses of a cooling agent, such as liquid nitrogen, in a cryopreservation device. The recovery assembly comprises a coneshaped funnel assembly (32) comprising a support (40) for mounting the funnel assembly (32) to an access opening of a cryopreservation container (16) to be at least partially filled with the cooling agent (12). When extracting a specimen holder (18) from the container, excess cooling agent can be collected and fed back into the container by means of the cone-shaped funnel portion. The funnel assembly may comprise an iris blind assembly (36) for modifying the the size of a through opening of the funnel assembly. At least one outwardly extending recess (38) may be provided to support a specimen holder in an inclined orientation above the blind's through opening.
