The first embodiment of the device a fluid float chamber with an internally sealable top opening which opens into an upper fluid passage. A floating ball is located in the fluid float chamber and is sized to be sealable at the top opening. A non-floatable ball is sized to seat on a lower seat through which fluid can enter the fluid float chamber. A vacuum line connects between the top opening and the sealed pressure vessel. The second embodiment of the device has a vacuum chamber into which is received a fluid sample container. A fluid supply tube connects between the vacuum chamber and the fluid inlet. A fluid overflow tube also connects between the vacuum chamber and the vacuum cylinder.
