The present invention, in some embodiments thereof, relates to a method and scalable devices for hyperfast cooling and re-warming of samples. More specifically, it relates to cryogenic preservation of biological samples via vitrification. It includes: a liquid sample placed at ambient temperature in a flat thermo conductive container that in some embodiments additionally contains a detachable disposable or sterilizable thermo conductive spiral; transferring the sample to a cooling chamber using a linear percussion stepping motor drive; hyperfast cooling of the sample using streams of pressurized liquid coolant; transferring the sample to a detachable shipping/storage chamber filled with liquid coolant, from which the sample can be transferred to another vessel that contains liquid cryogenic coolant and moved back to the shipping/storage chamber. This chamber can be then attached to a re-warming chamber, in which the sample is heated to a biologically tolerant temperature above 0 degrees Celsius in a hyperfast manner.

A refrigerator includes a first guide hole located at a first inner wall of a storage compartment, a second guide hole located at a second inner wall of the storage compartment, a first rotating bar that includes a first rotating shaft fitted in the first guide hole, and a second rotating bar that includes a second rotating shaft fitted in the second guide hole. A shelf is rotatably supported by the first rotating bar and the second rotating bar and is adjustable in height based on rotation of the first rotating bar and the second rotating bar. Also, the first guide hole has a first space that extends in a forward and rearward direction and that allows the first rotating shaft to slide and the second guide hole has a second space that extends in the forward and rearward direction and that allows the second rotating shaft to slide.

An automated, ultra-low temperature freezer having multiple structural features that reduce heat transfer into the freezer, protect its internal mechanical devices against low temperature mechanical binding of their movements, allow defrosting and autoclaving as a result of only minimal changes to the conventional CO2 emergency backup system. A group of freezers are arranged so they can simultaneously provide an HVAC function. A vial management system allows biological samples or vials to be automatically placed in and recovered from the freezer and associates the temperature history with each sample or vial that it was subjected to during its storage.

There is provided an ice making method capable of forming ice to an intended level although a sensing unit configured to sense whether or not a formation of ice has reached the intended level malfunctions. The ice making method includes: an ice making initiation step S100 of forming ice by an ice formation unit; an ice release time determining step S200 of determining a point in time at which ice is to be released in consideration of a signal from a detection unit for detecting whether the formation of ice has reached an intended level and an ice making lapse time which has lapsed after the formation of ice was initiated by the ice formation unit; and an ice releasing step S300 of releasing the formed ice when a point in time at which ice is to be released is determined in the ice releasing time determining step.

An adjustable shelving assembly includes at least two support rails, at least one geared rack provided in each of the at least two support rails, and an actuating mechanism placed adjacent to the at least one geared rack. The actuating mechanism is configured to support at least one shelf and facilitates movement of the at least one shelf along the at least two support rails. The actuating mechanism includes a pinion mating with the at least one geared rack, a plurality of permanent magnets mounted coaxially inside the pinion, ferromagnetic disks provided on either ends of the pinion, and a shaft placed axially in the pinion, connecting the permanent magnets. The permanent magnets magnetize or demagnetize the ferromagnetic disks when the shaft is rotated for locking or unlocking the at least one shelf.

The present subject matter relates to a dispenser (102, 202, 302) for storing, preserving, and delivering a plurality of food items. The dispenser (102, 202, 302) includes a loading bay (104, 306) for placing the plurality of food items in the dispenser (102, 202, 302); a plurality of chambers (304) for storing each of the plurality of food items; an automated scanning unit (106, 308) for scanning the plurality of food items placed in the plurality of chambers (304); an automated dispensing unit (108, 310) for dispensing an identified food item from the plurality of chambers (304); and a controller (112) for controlling climate conditions within the dispenser (102, 202, 302); actuating the scanning unit (106, 308); identifying a food item, and operating the dispensing unit (108, 310) to dispense the identified food items.
摘要:
A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g. −80° C. or −135° C.) or cryogenic (e.g., about −140° C. to −196° C.) storage and retrieval system that stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are normally stored within an ultra-low temperature or cryogenic freezer compartment. The tube picking mechanism includes a tube picking chamber that is maintained at about −80° C., about −135° C. or at cryogenic temperatures in cryogenic applications. Active electrical and mechanical components are maintained in a compartment above and separate from the refrigerated, ultra-low temperature or cryogenic compartment. Thermal stratification inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment in which tube picking occurs from the upper compartment in which active electrical and mechanical components are located, and also inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment via an access door for tube storage racks.
摘要:
Provided is a storage system and a refrigeration appliance including the storage system for storing food items in a temperature-controlled environment. The storage system includes a bin and a tab attached to the bin. The tab is configured to couple the bin to a track and guide the bin along a continuum of positions on the track. The storage system further includes an actuator attached to the bin that is selectively movable between a first position and a second position. The storage system still further includes a pin slidingly engaged with the bin. The bin is movable into a plurality of positions relative to the track. The pin in an engaged position is configured to prevent movement of the bin at any desired point within the continuum of positions on the track.
