Abstract: A multilayer plastic container for storing lyophilized products includes at least three layers consisting of inner and outer layers having a moisture vapor transmission rate of not more than 0.1 gm mil/100 sq. in.-day at 73° F. and 95% rh, and an intermediate layer of hygroscopic resin construction having a moisture content less than 1000 ppm. The hygroscopic intermediate layer preferably comprises at least 30% of the total thickness of the three layers. The inner and outer layers preferably are of cyclic olefin polymer or cyclic olefin copolymer construction, and the hygroscopic intermediate layer preferably is of amorphous nylon construction. The container preferably is empty and sealed within a secondary container, such as a metallized bag, that is impervious to moisture.

Abstract: A reversible cooling/heating system has an in-line accumulator/dryer unit. The accumulator/dryer unit has a body having first and second ports. A foraminate conduit is positioned at least partially within the body. A desiccant at least partially surrounds a first portion of the conduit.

Abstract: A hydrogen peroxide vapor generation unit (10) receives hydrogen peroxide and water solution at an interface (20) and interconnects with an air dryer (14) by way of nipples (72, 92). In one embodiment, the dryer includes a clamping assembly (42) which is latched (74, 94) with the nipples and which receives a disposable desiccant cartridge (40). In an alternate embodiment, a reusable desiccant cartridge (40?) is connected directly to the nipples (72, 92). When the desiccant cartridge (40?) is saturated, it is removed and placed in a regenerator unit (120). A regenerated cartridge is installed in its place.

Abstract: A chamber system for cryosorption freeze-drying of biological specimens in a Dewar vessel, comprises a chamber having a cylindrical metal wall and fitted within the Dewar vessel, a lower outer edge of which chamber is connected in a vacuum-tight manner to a lower edge of a metallic rotational component, the metallic rotational component having a bottom contact surface, which bottom contact surface corresponds with a complementary top contact surface on top of a cylindrical body around which liquid nitrogen flows and cools the metallic rotational component, the rotational component having a chamber to receive a drying agent for conducting cryosorption, for example a molecular screen, as well as a connection to the drying chamber.The upper edge of the metal wall or a ring connected thereto in a vacuum-tight manner is situated outside the Dewar vessel and is therefore approximately at ambient temperature and has a vacuum connection for the connection of commercially available vacuum components.

Abstract: Disclosed is a process for supplying cold to at least one refrigerated enclosure particularly an open enclosure for the display and sale of fresh products in a supermarket, characterized in that:a) in the sales point are disposed said open enclosures provided in manner known per se with cold air dispensing and recovery nozzles, passing through the interior of the enclosures, the air streams sweeping the products displayed and the air heating up by taking calories exchanged from the products;b) there is positioned in a zone offset with respect to said enclosures and chosen for its convenient access, an air cooling plant principally comprising an evaporator of refrigerant liquid-gas and a ventilator, this plant is furthermore supplied with refrigerant by a refrigerating unit;c) the cold air coming from the evaporator of said plant is entrained by forced circulation through appropriate pipes towards said enclosures, the cold air coming from the air cooling plant being delivered to cold air dispensing nozzles ser
