ABSTRACT:
An apparatus and method for sampling fluids is disclosed where the apparatus includes a body having a chamber therein, a control valve disposed in a control passageway in the body and a sample valve disposed in the sampling passageway in the body. The sample valve includes a freely movable valve member having a specific gravity less than the steps of pressurizing the chamber to force the valve member into sealing engagement with the sampling passageway and lowering the device into the fluid to be sampled to a predetermined depth were in the hydrostatic pressure on the valve enables the valve to move into the chamber permitting sampling fluid to fill the chamber. The sample valve floats on the fluid and seals the chamber when it is filled.
