A device for performing a plurality of immunochemical assays simultaneously comprises a waste reservoir (11) about which are positioned at least two assay tubes (16) connected in series by means of conduits (32) (38) formed in the base (12,30) and top (25) of the reservoir structure. A compound syringe (20) is insertable into an opening (29) formed through the top of the waste reservoir, the syringe being held in place by a receiving structure (47) formed in the base of the reservoir and connected to the entrance end of the series of assay tubes. The various compartments of the compound syringe are emptied in sequence to cause the flow of sample and assay reagents to flow through the assay tubes. The device is structured to allow for the reflow of sample through the tubes if desired. |
