1. A downhole sample extractor, comprising:
a sample container chamber that holds a sample container containing a downhole sample;
a sample extraction chamber; and
a first piston, that when actuated, inserts the sample container into the sample extraction chamber, wherein the first piston is connected to a flowline that forms a flow path between the downhole sample extractor and an analytical instrument, and wherein the first piston comprises an internal cavity that forms an internal flow path that connects the sample extraction chamber to the flowline.
