Abstract
Abstract A multiwell assay/culture strip provides an improved structure for a strip of wells as used for culturing cells and diagnostic testing, and comprises a strip or segment of generally identical well portions (typically eight or twelve wells) in linear arrangement adjacent one another and supported by a common base, and terminating in a first end and a second end. Each end bears a linking member extending perpendicularly from the end, and carries a receiver member conditioned to accept and frictionally engage an appropriate linking member of a separate strip. The linking members further provide offset basal surfaces to enhance stability of the strip.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A multiwell assay/culture strip comprising: a strip member having a base portion and a first and second end; a plurality of well portions supported on said base portion in linear, side-by-side arrangement; first male linking means located on said first end and extending some distance therefrom; first female receiver means located on said first end, said first female receiving means conditioned for releasable engagement with an identical first male linking means of another strip member; second male linking means located on said second end and extending some distance therefrom; and second female receiver means located on said second end, said second female receiving means conditioned for releasable engagement with an identical second male linking means of another strip member; wherein said first male linking means are not engageable with said second female receiving means, and said second male linking means are not engageable with said first female receiving means.
Claim 2
Dependent Claim
149 words
A multiwell assay/culture strip comprising: a strip member having a base portion and a first and second end; a plurality of well portions supported on said base portion in linear, side-by-side arrangement; first male linking means located on said first end and extending some distance therefrom; first female receiver means located on said first end, said first female receiving means conditioned for releasable engagement with an identical first male linking means of another strip member; second male linking means located on said second end and extending some distance therefrom; and second female receiver means located on said second end, said second female receiving means conditioned for releasable engagement with an identical second male linking means of another strip member; wherein said first male linking means are not engageable with said second female receiving means, and said second male linking means are not engageable with said first female receiving means.
Claim 3
Dependent Claim
42 words
The multiwell strip of claim 1 wherein said first male linking means extends perpendicularly in a first direction from said first end, and said second male linking means extends perpendicularly in a second direction, opposite said first direction, from said second end.
Claim 4
Dependent Claim
28 words
The multiwell strip of claim 2 wherein said first and second male linking means each bears a bottom surface, said bottom surfaces being coplanar with said strip base.
Claim 5
Dependent Claim
17 words
The multiwell strip of claim 3 wherein said base includes a recessed portion beneath said well portions.
