Abstract
Embodiments of a cryopreservation device and method of use are described that allow cryopreserved samples to be transferred from one location to another. In one embodiment, a cryopreservation device comprises two, telescoping tubes; one for plunging biological material into a reservoir of cryogenic liquid refrigerant, and the other for capturing the biological material along with some of the liquid refrigerant, for transferring the biological material to another location.
