Cryopreservation apparatus and methods

Apparatus are provided for preventing the formation of ice crystals in a biological sample containing a non-Newtonian fluid as a cryopreservation medium. The apparatus may be used to prevent ice formation during cryopreservation of biological samples, or during warming of cryopreserved biological samples, by changing the viscosity of the non-Newtonian fluid. The apparatus (200) comprises a housing (202) for a container (212) containing the biological sample (214) and the non-Newtonian fluid, and a device (204) for inducing a change in viscosity of the cryopreservation medium. The change in viscosity may be increased by inducing shear thickening of the cryopreservation medium, or the change in viscosity may be decreased by inducing shear thinning of the cryopreservation medium. Possible viscosity-changing devices comprise a tapping device, a piston, a rotating device, a compression device, a sound generating device, a permanent magnet or a electromagnetic field generating device. The apparatus may further include a temperature control device.

AIRTIGHT DEVICE

An airtight device includes a container and an airtight cover on the container, and the airtight cover includes a fixing bracket, a door, and a pressuring handle. The fixing bracket has a through hole and a guiding slot, and the through hole communicates with internal space of the container. The guiding slot has adjacent first and second top surfaces, and the second top surface is higher than the first top surface. The door selectively covers the through hole. The pressuring handle pivoted on the door has a first section, a second section, and a rotating axis between the first and second sections, and the first section rotates relative to the second section. The second section receives a force to drive the first section to move from below the second top surface to below the first top surface such that the rotating axis pressures the door.

Each of the beverage units includes a respective beverage unit outlet, and a respective support structure supporting beverage and orienting the respective beverage unit outlet. The dispenser includes a refrigerator in which the beverage unit(s) are receivable; a respective inlet, within the refrigerator, for each of the beverage units; at least one a dispensing outlet for dispensing beverage into drinking vessels; one or more fluid paths from the inlet(s) to the dispensing outlet(s); a guide arrangement co-operable with the support structure(s) to guide the beverage unit(s) so that each respective beverage unit outlet co-operates with its respective inlet to form a respective dry break connection through which beverage is conveyable on route to the dispensing outlet(s) via the fluid path(s).

Storage/containement unit for flexible pouch filled with biopharmaceutical fluid, and method of assembling a freeze/thaw containment system, using a protecting body of controlled deformation
11707413 · 2023-07-25 · ·

A flexible pouch is placed in a stack provided with two plates forming a protecting body to sandwich and constrain the flexible pouch. At opposite margin portions, the protecting body has slots cooperating with positioning members of an outer shell device belonging to the stack. Between the shell parts, the plates can move during filling of the pouch and the margin portions shrink inwardly in a protecting body plane. Some of the positioning members act as stoppers, in order to have lower clearance range for shrink strokes of the protecting body in a middle part thereof, as compared to a higher clearance range at respective longitudinal end parts of the two opposite margin portions. A higher constraining effect can be obtained in a center of the pouch, to limit maximum thickness of its content, which is of interest for managing freeze/thaw operations of biopharmaceutical materials contained in the pouch.
