Sample compatibility is excellent, since only Teflon ®, Viton ®, or Pyrex are used in the PV Tube. Adapters for a vacuum rack add a Polyethylene component to the list, though. With the PV Tube, sample size is limited to solutions or low viscosity suspensions that can pass through a 0.8mm constriction without clogging.
