ABSTRACT:
A durable, low cost, disposable, single test reagent package with plural compartments that maintain reagents separate during long term storage and permits combining of compartment contents without opening the vessel in a simple, rapid, and controlled manner includes a body component and an imperforate cooperating cover component. The body component defines a central compartment and an annular compartment surrounding the central compartment. Each compartment is upwardly open with annular ridge structure between the two compartments, and reagent material is stored in at least one of the compartments. The cooperating cover component has peripheral rim structure that is sealingly attached to cooperating rim structure of the body component to provide an hermetically sealed vessel, and includes integral depending annular seal structure for reclosable sealing engagement with the annular ridge structure of the body component and annular flexible web structure that permits movement of the seal structure between a position in sealing engagement with the annular ridge structure and an open position in which reagent material in the central compartment may be flowed under centrifugal force over the annular ridge into the annular compartment while the package remains sealed.
