With the 3500 there is less risk of lost samples due to battery failure. Both models incorporate a nickel-metal hydride (NiMH) battery which, unlike a NiCd 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. Plus, the indicator more accurately displays remaining life throughout the sampling period. You get faster charging too. The NiMH battery charges in under four hours. And you won’t be hampered with special storage or disposal requirements, since the NiMH battery is friendly to the environment.

Features of Gilian 3500

Power equals higher flow rates and higher back-pressure capabilities.   

Gilian 3500 provideS automatic constant flow from 700 cc/min to 3500 cc/min and 800 cc/min to 5000 cc/min. When used with a low flow module, they also handle low flows from 20 to 750 cc/min and 20 to 800 cc/min under constant pressure control, such as required for multi-flow sorbent sampling. These pumps offer significantly higher back-pressure capabilities than competitive pumps thanks to a more advanced pneumatic design and a more powerful power source. As a result, dense ­particulate buildup on the filter, such as with dusty environments is far less likely to trigger premature pump shutdown and an incomplete sample.    

the 3500 has an intuitive automatic restart feature that will attempt to save a sample should a fault occur. If the filter becomes clogged or tubing pinches not allowing air to pass, the pump will shut down and attempt to restart every 3 minutes for up to 30 minutes.
