Abstract: A culture package system comprising a package preferably in the form of a container containing one or more conventional culture media dishes containing solidified culture media. Each dish includes a bottom wall and a peripheral side wall and a removable cover having a bottom wall and a peripheral side side wall which is loosely telescoped over the dish. A plurality of the dishes are preferably provided in inverted stacked relation in the container. A cover is hermetically sealed to close the container. The interior of the package has a gaseous atmosphere having less than 1% oxygen. An oxygen absorber is placed in the package to facilitate maintaining the atmosphere at less than 1% oxygen. Preferably a moisture absorber is also placed in the package. The package is made of plastic material which is impermeable to oxygen and moisture and preferably is in the form of a container which has a base wall and a peripheral wall and a cover sealed thereto.

Abstract: Apparatus for performing and measuring chemical reactions includes a reaction test apparatus having reaction wells wherein reactants are controllably mixed, and exposure apparatus which receives and positions the reaction test apparatus adjacent a photographic film. Each of the reaction wells includes at least two reaction chambers, arranged in a side by side fashion. All but the final reaction chamber have upwardly sloping sides, so that liquid placed in one reaction chamber can flow to the next reaction chamber when the apparatus is tilted. In a preferred embodiment, the reaction wells are supported in a plate that is structurally integral with the wells but separates the wells from each other. The test plate is retained in the exposure apparatus, and liquid is controllably flowed from one reaction chamber to the next by tilting the exposure apparatus.

Abstract: A test slide (10) for performing diagnostic tests for detecting the presence of cells, their enzymes, metabolites and other cellular derivatives. The test slide (10) comprises a support strip (14), a coating (34) comprising a carrier and a diagnostic reagent disposed on the support strip (14), and a mount (12) comprising a front wall (18) and a rear wall (20).

Abstract: A culture media package comprising a container having a bottom wall and a peripheral side wall which is substantially filled with a culture medium, a removable insert over the top wall and having a portion defining a planar undersurface and a removable protective cover over the container and insert. The container and insert have radially extending flanges which are bonded to one another. The package is made by filling the container with a molten culture medium in a sterile environment, bonding the insert to the container in a sterile environment, inverting the sealed container such that the molten medium contacts the planar surface of the insert permitting any gases and bubbles to rise toward a space adjacent the bottom of the container and maintaining the container with the insert thereon in an inverted position until the medium has solidified. The removable cover may be applied to the sealed package of the container and insert either before the sealed package is inverted or after the medium has solidified.
