Offering flow rates up to 3500 cc/min, the GILIAN
3500 Pump assures you of successfully completing
samples, with fewer problems, thanks to several
advanced features. It eliminates the main cause of
premature battery failure and overcomes higher back
pressures. The air flow display holds calibration for
30 days, even with atmospheric changes. And it’s the
easiest pump to understand and use on the market
today. All of which save you time and money.

With the 3500, there’s less risk of samples
being ruined because of the battery failing.
It uses a nickel-metal hydride battery
which, unlike a NiCad battery, doesn’t
suffer from “memory” problems.
So there’s no hidden loss of battery capacity, no shorter-than-expected run time. And no need for special
battery maintenance. You use our standard charger and get the same, highly predictable life, charge after
charge.
When the display indicates a “full” battery, that’s exactly what the pump delivers...full run time. Plus, the
indicator more accurately displays remaining life throughout the sampling period.
You get faster charging, too. The 3500's NIMH battery fully charges in just five hours. And you won’t have
to fuss with special storage or disposal requirements, since the NIMH battery is environmentally safe.
