Abstract
A vessel for conducting blood cell agglutination assays is disclosed. A barrier retains reactants in an upper chamber during incubation, then, in response to a force, permits reagents to enter a lower chamber containing a matrix for separating agglutination.
Claims10
A liner for preventing cross-contamination of reagent or solution from one column of an agglutination assay cassette to another column of said cassette, wherein said liner comprises a body and at least one conical member depending therefrom, wherein said conical member has an aperture at a narrowed apex thereof, and wherein said conical member has sealing means located at a position spaced from said narrowed apex.
A liner comprising a body and six conical members depending therefrom, wherein each conical member comprises a first end spaced from said body and having an aperture at a narrowed apex thereof and a second end spaced from said first end having an o-ring surrounding and integral with said conical member.
A foil sealed cassette comprising six reaction vessels linearly arranged therein, and a liner comprising a body and six conical members linearly depending therefrom, wherein the conical members comprise a narrowed apex capable of puncturing said foil seal, and when inserted such liner is frictionally engaged in said cassette so as to seal a junction between the cassette and the liner.
