A downhole formation fluid sampler. The sampler includes at least one sampling chamber having an internal fluid chamber, a fluid inlet operable to receive a formation fluid and a fluid outlet. An inflatable bag is disposed within the internal fluid chamber. The inflatable bag is operably associated with the fluid inlet. A fluid cushion is disposed within the internal fluid chamber exterior of the inflatable bag such that filling the inflatable bag with the formation fluid through the fluid inlet displaces the fluid cushion from the internal fluid chamber through the fluid outlet. |
