Abstract
A cooling system (1), especially for cryopreserving biological samples (2), comprises a cooling chamber (100) delimited by a bottom area (110), side walls (120), and a top area (130), and a cooling device (200) for cooling the cooling chamber (100) using liquid nitrogen (220). At least one of the side walls (120) includes at least one predetermined wall element (125) which is a portion of at least one of the side walls and can be moved relative to the associated side wall (120) in such a way that a wall opening can be formed in said side wall (120). Methods for operating the cooling system (1) in case of an emergency are also described.
Claims17
A cooling system for cryopreservation of biological samples, comprising:
- a cooling chamber, which is delighted by a floor area, side walls and a ceiling area,
- a protection device, wherein the protection device is in the cooling chamber is configured for creating a local protective atmosphere in a environment of an operator, and comprises:
- (a) a hood which is movable in the cooling chamber, or (b) movable partition walls, which are shiftable in the cooling chamber, and with which a chamber can be created in the cooling chamber;
- an external ventilation system for impingement of an interior of the hood or an interior of the chamber with heated air, and
- a cooling device, which is provided for cooling of the cooling chamber with liquid nitrogen, wherein
- at least one of the side walls contains at least one predetermined wall element, that is a subregion of the at least one of the side walls and that is movable relative to the at least one of the side walls such that a wall opening can be formed in the at least one of the side walls.
