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.
