A system and method for automated processing of nucleic acids and other samples includes a disposable container comprising a tray and a flexible barrier. The barrier is configured to seal with a top edge of the tray, providing a closed, aseptic work area within the sealed tray. A pipette head and/or other sample manipulation device can be attached to the inside of the barrier, and the barrier can include an interface for a robotic arm or other device. When the barrier is sealed over the tray, the barrier separates the contents of the tray from the robot or other manipulation device. The barrier can be flexible, and allow the robotic arm to move the pipette head throughout the work area of the tray. All samples, reagents, pipette tips and other tools or devices for processing nucleic acid samples may remain within the closed compartment provided by the container during processing.

A storage facility for semiconductor containers is provided. The storage structure has partitioning walls including a side wall portion extending along a vertical direction, and holding space partitioned off from exterior space by the partitioning walls.

And a first opening for allowing containers being carried into and out of the storage structure to be moved through the side wall portion is formed in the side wall portion. A first inlet opening is located at a position which is in the exterior space and is adjacent an edge of the first opening. And a first drawing-in device is provided in the storage structure to discharge air drawn in through the first inlet opening into discharge space which is outside the holding space and is divided off from the exterior space.

The present invention relates to a laboratory incubator, more particularly, a gassing incubator, comprising an outer housing incorporating a door and an inner housing surrounding an internal chamber, which comprises a floor, a ceiling, three side walls and a lateral surface that is capable of being closed by said door or by an additional, inner door, and in which a flow channel is present, which comprises at least one air inlet opening in an end region and at least one air outlet opening in a different end region, wherein said at least one air outlet opening is formed such that effluent air is guided along at least one of the side walls and/or the lateral surface in the peripheral region of the internal chamber, and wherein a water reservoir capable of being heated is disposed within the flow channel such that air flowing in the flow channel is passed across or through said water reservoir.

An isolator includes a work chamber, a sterilizing substance supply unit, a gas flow channel pressure adjustment unit, a work chamber barometer, and a controller. The controller is configured to control execution of a gas flow channel leak test for checking a gas leak in a gas flow channel based on a detection result by the work chamber barometer after making the gas flow channel pressure adjustment unit increase or decrease the pressure in the gas flow channel, and is configured to control supply of the sterilizing substance by the sterilizing substance supply unit. The controller performs heating of a heater, which accompanies the supply of the sterilizing substance, in parallel with the gas flow channel leak test.

The present invention relates to an externally operated alpha port for a rapid transfer port (RTP) system such as those found in isolation barrier systems. Means are provided for the actuation by the operator of the alpha port door locking system externally of the isolation barrier to facilitate the locking and unlocking of the alpha port door without requiring gloved entry into the isolation barrier. Means are also provided for opening and closing of the alpha port door with the actuation by the operator of a lever external to the isolation barrier.

Rapid transfer port (RTP) systems for transferring articles between two environments (e.g., an isolator barrier system and a transfer container) are provided. Such systems may be adapted to be mated to one another by a docking operation. More particularly, such systems may provide a container assembly for use with an RTP of the type that does not require the transfer container port (beta port) which mates, for example, with the isolator barrier system port (alpha port) to breach the integrity of the container until attachment to the isolator barrier system port (alpha port 9). The container assembly may have an enclosure that, during docking, is not required to be exposed to the clean environment such as an isolator barrier system.

The invention provides efficiently automated incubation devices that reduce the number of powered moving parts in the devices and the amount of air transfer between environments that are internal and external to the devices. Related systems are also provided.

The present invention relates to a laboratory fume hood, especially a safety cabinet, comprising a working space which is enclosed by a housing and which is closable by an especially movable front window. It comprises a projection apparatus in order to project an image into the working space.

Disclosed is an inspection apparatus that includes a cartridge including a container which is at least partially structured with an elastic member, the container including inside thereof a plurality of rooms to contain solution and a passage to connect the plurality of rooms; and a housing which is arranged with a liquid feeding device which conducts inspection of the solution by applying external force to the elastic member to move the solution in the passage or in at least one of the rooms, wherein the housing is sealed air-tightly from outside air, and the housing is a safety cabinet to which a sterilization filter is provided at an outlet passage thereby that communicates from inside to external of the housing.

An apparatus and a process for forming a protective barrier seal along a “ring of concern” of a transfer container used with double door systems is provided. A protective substrate is supplied between a “ring of concern” and a safety cover in which an adhesive layer of the substrate engages the “ring of concern”. A compressive foam strip along an opposite side of the substrate engages a safety cover such that a compressive force is maintained between the “ring of concern” and the adhesive layer of the substrate.

An insulated chamber having an interior region for storing items therein includes a phase change material to facilitate controlling the temperature of the interior region and the items. A heating device or cooling device may be used to melt or freeze the phase change material. The phase change material (PCM) may be in various locations such as the walls of the chamber in the form of packets or in the form of containers that serve as shelves and may be removable from the interior region. The packets may have recesses for receiving the items. The phase change material may be within capsules that may be within a liquid or a solid matrix. Controls may be provided to control humidity, oxygen, and carbon dioxide within the interior chamber.

A lyophilization nest and method of using the same is described herein. In various embodiments, the lyophilization nest is configured to support one or more receptacles each supporting one or more substances within an interior space of the lyophilization nest. The interior space may be in fluid communication with the exterior of the lyophilization nest through one or more vent holes extending through a surface of the lyophilization nest. Each of the one or more vent holes have a corresponding sealing element configured to selectively form an air-tight seal within the vent holes, such that a controlled environment may be maintained within the interior space when the ambient conditions surrounding the lyophilization nest are not lyophilization conditions. The one or more sealing elements may be operable while the lyophilization nest is positioned within a sealed lyophilizer by depressing the sealing elements into corresponding vent holes to form the air-tight seal.

An air-conditioning apparatus regulates at least the temperature of at least one room to a predetermined temperature desired value (T_{RAUM SOLL}) by ventilation with heated or cooled supply air. The air-conditioning apparatus has a supply air motor (15) which feeds the supply air through a supply air channel (10) to the room (1) to be air-conditioned, a cooling and/or heating device (30, 40 33) for the cooling or warming of the supply air, and an exhaust air motor (16) which draws the exhaust air from the room (1) to be air-conditioned through an exhaust air channel (11). The desired value (P_{AB SOLL}) for the regulator of the exhaust air motor (16) forms a room excess pressure established with respect to the outside pressure (P_A).
