A probe apparatus for aspirating a liquid sample from a container including a probe and a probe tip. The probe tip has a free end including a plurality of sharp points and cutting edges formed by the juncture of exposed surfaces. The exposed surfaces have a length and shape which promote liquid movement by surface tension forces along the exposed surfaces. A filter is secured to the end of the probe tip and a passageway for liquid extends through the probe and probe tip.
