The original anti-static ‘gun’, Aerostat 3 is a non-invasive way to deal with static, a perennial analogue replay issue.
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. Don’t be concerned about the clicking noise it makes in operation. There is a simple method for testing the unit. If you fit the nozzle supplied it can be seen to glow through the slot when ions are passing.
How much charge is given off?
Each squeeze of the trigger results in a discharge which when stated in units of charge, is 1.5 Coulombs.
How long will it last?
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.
