Abstract
A device and method for filtering a biologically derived sample and for mixing the sample with a reagent, comprising a fluid container defining a reservoir compartment and including a container outlet, a filter and a fluid flow-through matrix disposed in a flow path between the reservoir compartment and the container outlet. Water-soluble, dried reagent is retained on the matrix. Means is provided for urging sample in an aqueous liquid in the reservoir compartment through the filter and matrix and out the container outlet. Pressure is applied to the sample in an aqueous liquid in the reservoir compartment to cause the sample to flow in liquid through the filter and matrix and out of the container for analysis.
