An oceanographic sampling bottle providing low drag for a rapid descent rate and low susceptibility to leakage after sample acquisition. The sampling bottle comprises streamlined inlet and cutlet valve members shaped and positioned to avoid flow separation. The bottle with valves occupies a relatively small cross-sectional area facilitating design of a rosette or cluster of bottles. A hollow resilient conduit interconnecting the inlet and outlet valves draws the valves against seats on the sampling bottle when released. Vents in the conduit provide pressure equalization.
