<p>A sampling tool (100) to sample formation fluids in a wellbore is disclosed. The sampling tool may include a sample chamber (270, 370) having a fluid inlet port and a tubular portion. A first piston (205, 305) may be sealably and movably disposed within the tubular portion (270, 370). One or more surfaces of the first piston (205, 305) and the sample chamber (270, 370) may, at least in part, define a sample space. A second piston (240, 340) may be sealably and movably disposed within the first piston (205, 305).</p> |
