A fluid collection, filtration, and storage device is described. The device has a first tube (20) with a closed first end, an open second end, inner tube-wall surfaces, and an internal diameter, a second tube (10) with a first end porously closed by a filter and an open second end and having an external diameter smaller than the internal diameter of the first tube (20), the second tube (10) further slidably contacting the inner tube-wall surfaces of the first tube (20) at the first end of the second tube (10) when the second tube (10) is inserted in the first tube (20); and a cap (30) adapted to seal the open second end of the first tube (20) and the open second end of the second tube (10) in a single closing operation while the second tube (10) is inserted into the first tube (20). The kit is particularly adapted for collecting and storing viscous biologic samples, such as saliva, in the inner second tube (10) after the sample has been mixed with a preservative or other substance initially located in the filter.
