A multi-purpose device for sampling, collecting, recovering and storing of fluid samples, including recovery tube (12), a fluid absorbent medium comprising a cellular foam component (16), and a closure (14), which is physically coupled to the fluid absorbent element, and adapted to seal the fluid absorbent medium within the sample recovery tube. The sample recovery tube of this multi-purpose device comprises a resilient, preferably transparent, tubular member (12) having an open end and a closed end. The open end is provided with means for sealing engagement with the open end of a closure (14). In the preferred embodiments of this device, the closure is of composite construction and includes a vent or fluid channel (11) in the closed end thereof to permit access to a liquid or a gas within the sample recovery tube, and is yet essentially restrictive of fluid transfer under ambient conditions. |
