An adsorbent system and a dry vapor cryogenic shipping container are provided. The container includes an outer shell surrounding an inner vessel with an evacuable space therebetween. The container includes the adsorbent system, which includes a primary adsorbent disposed within an interior of the inner vessel and a secondary adsorbent that is disposed within the interior of the inner vessel adjacent a portion of a bottom wall of the inner vessel. The primary adsorbent and the secondary adsorbent adsorb a liquid cryogen, such as liquid nitrogen, at different rates. The primary adsorbent has a liquid cryogen adsorption rate that allows the container to be charged quickly with liquid cryogen, while the secondary adsorbent has a liquid cryogen adsorption rate that is less than the primary adsorbent and adsorbs liquid cryogen that may desorb from the primary adsorbent.

In a vacuum heat insulating double walled container 1, adsorbent blocks 30 are formed in block, and each of the adsorbent blocks 30 disposed on the peripheral surface of a sample storage container 25 is placed on a partition plate 27. Moreover, an inner container 10 is hang in an outer container 3 using a connecting tube 20 formed of a thin material having an uneven outer peripheral surface, and a heat insulating tube 40 is disposed on the inner surface of the connecting tube 20. Further, as to a workpiece carrier 50 as a fixing device, a carrier guide 52 is in close contact with the heat insulating tube 40, and a plate-like portion 54 and a workpiece storage portion 51 are disposed in a non-contact state with respect to the sample storage container 25. As a result, it is possible to suppress the amount of heat transferred from the inner container 10 to the outer container 3, and vibration and impact is less likely to applied to a sample in the workpiece storage portion 51 even if an external force such as impact is applied to the vacuum heat insulating double walled container 1.

A portable cryogenic container includes a porous material configured to absorb a cryogenic coolant such as liquid nitrogen. The coolant-absorbing material at least partially defines a storage cavity in the container that is configured to accept and support a cassette or other type of contents container in which a product to be cryogenically stored is contained. With cryogenic coolant absorbed into the container, the temperature within the storage cavity can be maintained sufficiently close to the boiling point of the cryogenic coolant to preserve post-thaw viability of the stored product for several hours.

A picnic cooler that includes a food compartment, a gas tank compartment, an off/on electric spigot, two sealing rings with fixed-size apertures, and two cooling apparatuses. The cooling apparatus includes a twisting piping system and an upper metallic plate that serves as the bottom of the food compartment.

A cryogenic treatment system has a housing that includes a dispensing nozzle operably connected with a CO2 dispensing conduit that includes a valve for controlling the flow of CO2 therethrough. A connector fitting is adapted for operably connecting the CO2 dispensing conduit with the separate CO2 source, which is not mounted on the housing. A temperature sensor is operably mounted for monitoring the temperature of a treated area of the patient, and an accelerometer is operably mounted for monitoring movement of the housing. A computer controller is operably connected with the temperature sensor and the accelerometer for controlling the valve responsive to the temperature sensor and the accelerometer.

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.

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.

The present invention relates to an apparatus for freezing samples such as tissue specimens, particularly for rapidly freezing multiple specimens without the need to sequentially prepare and freeze each sample individually. The apparatus comprises a mold which can accommodate one or more tissue samples, a hands-free means for supporting the mold, an insulated container for holding a cryogenic material or refrigerant, and an optional cover for the insulated container. The invention also relates to methods for freezing the tissue specimens.

A portable drink holder for a drinkable liquid having a first removable reservoir for storing the liquid at a first end of the holder, a second removable reservoir at a second end of the holder for receiving the liquid and a cooling cartridge having a plurality of passageways for selectively transporting liquid from the first reservoir to the second reservoir. The cooling cartridge including a cooling medium so that the liquid transitions to a second temperature lower than the first temperature as it flows from the first reservoir to the second reservoir.

A picnic cooler that include a food compartment, a liquid-gas tank with an adapter, an electric spigot and a cooling apparatus. The food compartment includes a release aperture with unidirectional valve that is designed to release outside the gas. The cooling apparatus includes a twisting piping system and an upper metallic plate that serves also as the inner bottom of the food compartment and as a cooling plate. A second end of the twisting piping system includes a secondary aperture that is positioned inside the food compartment and that causes additional pressure drop and by that assists to cool the interior of the food compartment.
