A cartridge for holding an analytical sample during a diagnostic assay comprises a panel with a number of adjacent wells in its upper side. The wells have an upper opening and a lower opening and the lower opening extends to the underside of the panel. A filter membrane extends across the lower openings of the wells so that liquids contained in the wells may be drawn through the filter thereby concentrating suspended solids near the lower openings of the wells. The panel includes a supporting wall for supporting the panel on a non-integral, external surface which does not, form a part of the panel.

Why it's free to use
- Filed October 4, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 4, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 4, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
