Abstract of the Disclosure The hydraulic circuit contains a completely closed system such that the fluid can be transferred from the downhole sampler to the sample vessel without the exposure of hazardous gas or release of high pressure. Also, the circuit allows for the calculation of the bubble point pressure before the sample is drained. A feature of the circuit includes having a first pump, hooked up to a fluid reservoir, and an output to one side of the sample chamber. Another feature includes a second pump which will displace fluid in the hydraulic circuit. The third feature includes a sample vessel that contains a piston. Yet another feature includes at least one pressure port in the conduit which leads to a Data Acquisition System. Another feature includes the use of a fluid displacement pump.
