This amazing little device known as the Zerostat Antistatic Gun is an
antistatic "generator" which has numerous applications in any microscopy
laboratory. Just squeeze the "trigger" of the Zerostat and a steady stream
of ions is released. The "magic" comes from two powerful piezoelectric
crystals and a patented compression trigger.
Originally developed for removing dust from "vinyl" and before that, normal
"phonograph records". In later years the Zerostat antistatic gun was
discovered to have great applicability for use in a photographic darkroom
to remove dust from film and negatives. After that, a wider range of
applications came into being when people running SEM labs found out that
it was also ideal for eliminating dust from critical samples or other
critical surfaces when the dust attraction was being caused by electrostatic
charge. Others have reported that certain insulating specimens, when
treated this way, can actually be viewed (admittedly briefly) by SEM without
the need to apply further coating.
Each Zerostat unit has a "two cycle" type of operation. When the trigger is
squeezed, positive ions are generated and when the trigger is relaxed,
negative ions flow. This means that it is possible to induce a charge on a
neutral surface using the Zerostat. If the trigger is squeezed, and the
Zerostat is removed from the surface before allowing the trigger
to return to its original position, a positive charge will be induced.
Similarly, pointing the Zerostat at the surface only for the release of the
trigger will induce a negative charge.
Each squeeze of the trigger results in a discharge which when stated in units of charge, is 1.5 Coulombs.
One can reasonably expect on the order of 10,000 "squeeze cycles" during
the lifetime of the Zerostat unit. No batteries or electrical supply required.
Static reduction lasts for hours. No polymer residue is left behind.
The Zerostat 3 is designed to be a disposable (throw-away) product. It is not built to be
taken apart and there are no replacement parts.
