Proposed is a filter fixing module mounted to a handpiece cooling device having a connecting unit such that a refrigerant supply unit is coupled thereto, the filter fixing module including a body having a support surface formed in a plate shape, and a receiving surface formed on an edge of the support surface and protruding in a first direction relative to the support surface so as to prevent removal of a filter received in the support surface, and a grip unit connected to the body, wherein the grip unit comprises a first grip member and a second grip member extending in directions opposite to the protruding direction of the receiving surface relative to the body.

A low-temperature storage device includes an inner vessel, an outer vessel about the inner vessel, a thermal insulation layer between the inner vessel and the outer vessel, and a single heat exchanger in thermal communication with an interior of the inner vessel and adapted to be connected to at least one of an evaporator in a closed-loop refrigeration circuit and an open-loop evaporator for an externally-supplied cryogen. The inner vessel can be a vacuum-insulated vessel, and the heat exchanger can be an internal heat exchanger including at least two fluid circuits: a first circuit with one external connection and one internal connection into the inner vessel and the second circuit with two external connections.

The invention relates to a device for cryogenic freezing of units for packaging a biological substance comprising a receptacle (2) configured such that a stream of vapour of a cryogenic agent circulates therein, having at its top an insertion opening (10) for inserting the packaging units into the receptacle (2), a lid (3) that is able to move between a closed position in which it closes the insertion opening (10) and an open position in which it leaves the insertion opening (10) open, and a port (4) for discharging the vapour, provided in the receptacle (2), characterised in that the device (1) further comprises a stopper (13) mechanically connected to the lid (3) such that, when the lid (3) is in the closed position, the stopper (13) is spaced apart from the port (4) and, when the lid (3) is in the open position, the stopper (13) closes the port (4).
