Abstract: The present invention is a closed system storage plate that includes a specimen collection plate having a plurality of wells for storing specimens and a cover that is sealably secured to the specimen collection plate. The cover has a thermoplastic elastomer membrane that provides pierceable access by a probe to each well interior and self-seals upon removal of the probe.

Abstract: A multiwell tissue culture assembly for culturing cells comprising a plate and a lid. The plate includes a plurality of wells for accommodating a cell culture insert and the lid includes means for varying the gas diffusion into and out of the assembly and for substantially minimizing biological contamination of the cells being cultured in the cell culture insert. The means for varying the gas diffusion is a gas permeable membrane provided in an opening in the lid and a removable thin impermeable film label is provided for selectively occluding passage of gases through the gas permeable membrane.

Abstract: Apparatus for growing cells or tissue in vitro, which permits a concentration gradient of nutrients to develop through a permeable membrane to which a sample of tissue is attached. The permeable membrane is attached to the bottom end of a cell culture insert that in turn is supported by a flange connected to its upper end on the top of a well containing the nutrients. Restricted movement of the cell culture insert in the well may be facilitated by projections extending off the outer wall surface of the insert so as to avoid capillary action in the space between the well and the insert.

Abstract: The present invention is a chamber slide assembly having a base member, a cooperable vessel comprising a chamber and a neck wherein said vessel is removably attached to the base and a movable lever attached to the vessel for separating the vessel from the base. Preferably, the assembly may be used for carrying out biological reactions or growth therein, such as growing tissue or cell cultures.

Abstract: Apparatus for growing tissue cultures in vitro, which permits a concentration gradient of nutrients to develop through a permeable membrane to which a sample of tissue is attached. The permeable membrane is attached to the bottom end of a cell culture insert that in turn is supported by a flange connected to its upper end on the top of a well containing the nutrients and is self centered in the well by the arrangement of the sidewalls of the cell culture insert. The self centering feature of the insert minimizes capillary action.

Abstract: Apparatus for growing cells or tissue in vitro and for supporting, positioning and/or centering cell culture inserts that are used in such procedures. The apparatus comprises a body with a plurality of wells wherein a cell culture insert may be supported and centered without interfering with the growing of tissue culture in vitro.
