A fluid sample transfer device made of non-toxic inert material and preferably of virgin fluorocarbon material provides a sealed closed system for transferring a sample of the fluid to be analyzed for contaminants into a vial sealed by a self-sealing septum pierced by a pair of hypodermic needles of different length fixed to and extending from a bottom side of a body having a fluid inlet passage and a vent or outlet passage therein. A long needle is connected to the inlet passage and conveys fluid through and out its sharply pointed outlet end situated close to the bottom of a vial being filled therewithand a short hollow needle is connected to the outlet passage and extends to its pointed inlet end situated slightly below the septum of the vial to allow gas above the fluid filling the vial to escape. One embodiment has sealable means for connecting the upper portion of the body to a conventional bailer and a valve for selectively preventing or allowing passage of fluid to the long needle and vial. Another embodiment has sealable connecting means on the upper portion of the body for connection to a bladder pump and to a filter device and valve means for selectively preventing or allowing passage of fluid to either the long needle and vial or to the filter device. Guide means may also be provided for guiding a vial into and out of sealing engagement with the needles and the body.
