Described herein are systems and methods for freezing an alcoholic mixture using liquid nitrogen. The systems may comprise a ferromagnetic capsule configured to receiving an amount of alcoholic mixture, a cap comprising at least one magnet for magnetically sealing the capsule, a wand comprising at least one magnet for magnetically coupling to the capsule or the cap, and a vessel containing a quantity of liquid nitrogen maintained at or below its boiling point. In use, the alcoholic mixture can be poured into the capsule, the capsule can be sealed using the cap, and the wand can be used to submerge the capsule and the cap in the liquid nitrogen for a time sufficient to freeze the alcoholic mixture.

In some embodiments, a package for cooling a product includes an exterior package wall, an interior package wall coupled to the exterior package wall and defining an interior cavity for retaining the product and an opening for receiving the product into the interior cavity, a coolant supply unit configured to be activated to introduce coolant into a space between the interior package wall and the exterior package wall, and an electronic monitoring device including a temperature sensor and a control unit configured to activate the coolant supply unit to introduce the coolant into the space between the interior package wall and the exterior package wall in response to a detection by the electronic monitoring device that a temperature in the interior cavity is above a predetermined threshold. Systems and methods of cooling a product are also described.

A cooling device for cooling beverage containers and their contents, such as, but not limited to, twelve-ounce aluminum cans. The device comprises a cylindrical body open at its top and having a bottom, where said cylindrical body includes an inner wall as well as an outer wall so as to form a plurality of compartments. In use, a beverage container is inserted into the innermost compartment surrounded by the inner wall while a solvent is added to the annular compartment between the inner and outer walls which contains a salt coolant. The dissolution of said salt in said solvent induces an endothermic chemical reaction capable of instantly cooling the beverage container as well as its contents via contact with said inner wall. Separation of the solvent from said salt coolant allows for subsequent reuse of the cooling device.

The invention relates to a cryogenic container for storing and/or transporting a medium, in particular a biochemical and/or medical product. The cryogenic container comprises at least one primary container, which has at least one flexible film bag. The flexible film bag is designed to receive the medium. The cryogenic container furthermore comprises at least one secondary container, which at least partially surrounds the primary container and is preferably at least partially flexible. The secondary container has at least one opening for insertion of the primary container. The secondary container furthermore has at least one preferably at least partially flexible outer sleeve. The secondary container furthermore has at least one heat exchanger space, which is arranged between the outer sleeve and the flexible film bag and receives at least one fluid heat exchange medium.

The invention described herein generally pertains to a system and method related to a light device that is configured to attach to a dewar, wherein the light device delivers a light to an inside of the dewar for inspection or examination. The light device can include a first base member that is positioned to mate with an outside sidewall of a rim surrounding an opening on the dewar, wherein an arm is moveable to position a light to shine into the opening.

In some embodiments, apparatuses and methods are provided herein useful to delivering and maintaining perishable items within a certain temperature range during delivery. In some embodiments, there is provided a system for transporting merchandise including: a container for transporting merchandise within a predetermined temperature range in a delivery vehicle along a delivery route from a source location to a destination location, the container including: a merchandise storage area receiving merchandise and a coolant; an insulation compartment adjacent the merchandise storage area; a temperature sensor measuring the temperature in the merchandise storage area at predetermined time intervals during transport; and a control circuit configured to receive the temperature measurements from the temperature sensor during transport and to modify the insulation characteristics of the container during transport in response to the temperature measurements to maintain the merchandise within the predetermined temperature range.

An assembly for cooling a liquid inside a portable container. According to some implementations the portable container has a heat exchanger assembly disposed therein with the heat exchanger assembly including a coolant pre-cooling assembly. According to the same or other implementations a tortuous coolant fluid passage that runs through at least a portion of the heat exchanger assembly includes one or more constrictions for controlling the evaporation temperature of the coolant along the length of the passage.

Standalone and self-contained cooling systems using compressed liquid and/or gas CO.sub.2 containers positioned in an insulated or non-insulated vessel and consisting of a specially designed unit where the containers are vertically positioned in an upright or upside-down position.

The liquid and/or gas CO.sub.2 coolant is then released into capillary tube(s) embedded into a heat transfer plate or heat exchanger thus leveraging the CO.sub.2 coolant properties.

The temperature is controlled by a metering CO.sub.2 releasing system encompassing an electronic control device which can be operated remotely and/or via a touch screen and which sends alerts when pre-defined thresholds are exceeded.

The invention's metering CO.sub.2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid. The invention's cooling system also encompasses check valves, which avoid liquid and/or gas CO.sub.2 from escaping when removing or replacing CO.sub.2 containers individually.
