A gas-selection device for a sealed storage container with modified or controlled atmosphere, remarkable in that it includes a hollow body and at least one first orifice, a second orifice and a first membrane, said first and second orifices connecting the inside of said body to the outside, said first membrane being disposed inside said body between said first and second orifices so that the gases flowing from the first orifice to the second orifice, or vice versa, necessarily and solely pass through said first membrane, and in that the device is arranged so as to be secured sealingly to one of the walls of the container, so as to allow a flow of gas from its second orifice through the wall, or vice versa.

A method of controlling gas composition within a container containing respiring produce is described. The container includes at least one gas outlet and at lease one gas inlet and the method includes the steps of: drawing a selected gas from within the container through a selective membrane element and through the at least one gas outlet; detecting ambient pressure inside the container; and introducing ambient air under selected control conditions from outside the container into the container through the at least one gas inlet in response to the detected ambient pressure to control the relative composition of gases inside the container.

This product based on leaven comprises a package containing living leaven closed with a gas tight seal. The leaven is in a nitrogen atmosphere.

A device for controlling package pressure and gas flow for a packaged good comprises a film having a first opening for exposure to the inside of a package and a second opening for exposure to the outside of a package. A channel extends between the first opening and the second opening. The dimensions of the channel are configured to control the rate of flow of CO.sub.2 (cc/min @ 1 PSI) from the inside of the package to the outside of the package and control the oxygen transmission rate (cc/day/Atm) from the outside of the package to the inside of the package so that a flow of CO.sub.2/OTR ratio is at an acceptable level for the packaged good.

A cartridge and a method for testing a biological sample are provided, wherein the cartridge is filled, in an open packaging, with the sample to be tested, and wherein the packaging holds and/or supports the cartridge in a latching manner in an open state.

A label with a microchannel for venting a package.

A pharmaceutical product includes a delivery syringe comprising a plastic receptacle and an oxygen-tight envelope which envelopes the delivery syringe in an oxygen-tight manner, wherein the plastic receptacle is filled with an oxygen-sensitive active pharmaceutical ingredient fluid and an inner surface of the plastic receptacle is siliconized at least in sections.

A transport container is a transport container for transporting a biological component being a cell or a collection of cells, and includes an ion generation device configured to generate a discharge product inside the transport container by discharge.

A pack including at least one single-use capsule or pod for a portioned beverage which has two opposite bases, and a side wall connecting the two bases defining therewith a chamber for containing an aromatic substance; the pack has a sealed container for containing the capsule or pod housed in a protective inert gas atmosphere; more specifically the sealed container copies at least in part the shape of the capsule or pod.

An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.
