A portable, hydrocarbon well test unit for use with high temperature and high-pressure hydrocarbon wellbore flow includes a two-phase separator unit having a hydrocarbon inlet, a vapor outlet and a liquid outlet. A static mixer is in fluid communication with the liquid outlet. A liquid sampler positioned downstream of the static mixer ensures that liquid and gas are mixed to accurately represent a sample of the wellbore hydrocarbon flow. The sampler can be actuated to extract a sample of the mixed fluid. The sampler directs samples to a multi-position valve having a plurality of valve outlets, each outlet being in fluid communication with one of a plurality of sample bottles. A controller actuates the multi-position valve to direct a sample into a particular sample bottle, thereby allowing different types of samples to be taken over different time periods without the need for intervention for extended periods of time.
