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