Scientific Instrument Services manufactures VG-FAB probe tips. These new probe tips are similar in construction to the original FAB tips but with a slightly larger and stronger alumina ceramic base. This results in a much more durable probe tip.
Three styles are available: the slanted design used on the majority of instruments (VG-FAB), the new straight design, (VG-FAB2), and the dual design (VG-FAB3) used on some of the newer instruments.
