A microbial culture transport apparatus comprising an open top receptacle having a first open-top culture device receiving area for receiving a culture sample and at least a second container retaining area, a cover for the receptacle, and a rupturable container in the second area containing a material for use in maintaining viability of a culture sample. Interengaging detents are provided on the receptacle and cover for releasably retaining the cover in a first position with the top wall of the cover spaced above the bottom of the receptacle to maintain the culture sample and rupturable container in their respective areas without rupturing the container, the interengaging detents being releasable on response to downward pressure on the cover to move down to a second position. A punch on the cover is operative when the cover is moved from its first and second position on the receptacle for rupturing the rupturable container to release the culture sustaining material therein and seals are provided on the cover and receptacle for sealing the areas in the receptacle from the outside atmosphere when the cover is in its second position.

Culture transport apparatus

A microbial culture apparatus including an outer sealable enclosure for receiving a culture retaining container and a self-contained anaerobic gassing and indicator apparatus which can be selectively activated to provide a gaseous atmosphere around the culture retaining container. The gassing and indicator apparatus includes an open top receptacle having a first rupturable container for producing a gaseous atmosphere, a second rupturable container containing a color indicator, and a catalyst, and a cover for the receptacle arranged to rupture both rupturable containers when the cover is moved to a closed position to activate the gassing and indicating apparatus. The outer enclosure comprises an outer open top receptacle for receiving the culture retaining container and the gassing and indicator apparatus, and a cover which can be moved to a closed position sealing the outer receptacle and activating the gassing and indicating apparatus.

Microbial culture apparatus

An anaerobic liquid storage and transport apparatus including a liquid receiver means for receiving and holding an anaerobic liquid, a gas generator container means having a self-contained gas generator for generating at least a reducing gas, conduit means for supplying gas from the gas generator into the liquid receiver means, conduit means for removing gas from the liquid receiver means, and a catalyst which promotes reaction between the reducing gas, when produced by the gas generator, and oxygen in, from and/or around the apparatus.

Anaerobic liquid transport apparatus

A package for storing, incubating or transporting an anaerobic culture comprising a bag of flexible sheet material of low gas permeability, a self-contained gas generating apparatus in the bag for generating at least a reducing gas, a culture retaining container in the bag, and a catalyst in the bag which promotes reaction between the reducing gas, when produced by the gas generating apparatus, and oxygen in the bag. The bag may also contain a color indicator apparatus which when activated indicates the presence or absence of oxygen in the bag by color change. Hydrogen is the preferred reducing gas which is generated, alone or in conjunction with carbon dioxide.

Anaerobic environmental system for bacteria culture testing

A color indicator apparatus for determining the presence of oxygen which comprises a container which permits flow of gas thereto, an ampoule in the container, said ampoule containing a redox color indicator liquid, and an absorbent material, for the liquid in the ampoule, in the container. Typically the redox color indicator is methylene blue or resazurin. The apparatus is useful for determining if an anaerobic atmosphere exists around a micro-organism culture.

Color indicator apparatus for presence of oxygen

A gas generating apparatus, for use in microorganism maintenance during sample transport, storage or incubation, comprising a container having an opening, a gas generating solid material in the container, an ampoule containing a liquid which is reactive with the solid material to produce a gas, said ampoule being openable from outside the container to free the liquid to contact the solid material, and means in the container which prevents liquid from flowing from the container after the ampoule is opened but which permits flow of gas generated in the container out of the container opening. A solid desiccant material may be put in the container to absorb water which may enter the container before the ampoule is opened, thereby preventing degradation or premature reaction of the gas generating solid material. A reducing gas, such as hydrogen, is generated alone or with carbon dioxide. The hydrogen catalytically combines with oxygen to form an anaerobic atmosphere.
