ISCO 3700 Waste Water Sampler

The 3700 Automatic Water Sampler collects composite or sequential samples based on flow rate, time or storm conditions. The ISCO 3700 sampler is ideal for waste water sampling and water quality sampling applications and is available with interchangeable 24-bottle and composite (single bottle) carrousels. The ISCO 3700's LD90 compensates automatically for changes in head height, plus automatic suction line rising to prevent cross contamination. The LD90 features a non-contacting liquid sensor which is not affected by temperature, viscosity, conductivity or liquid composition. Cleaning and tubing replacement is fast and easy, as there are no internal tubing connections. The ISCO 3700 automatic water sampler pump outperforms most competing samplers and maintains the EPA- recommended 2ft/second line velocity at head heights up to 16 feet, with ¼ - inch suction line. The 6700 Series is recommended for higher lifts.

Ample ice capacity and high-performance insulation in the base keep your samples cool. With 20 lbs of ice in the base and 4 gallons liquid collected at 65°F, the sample temperature is maintained at least 32°F below ambient for 24 hours.


The Isco 3700 Waste Water Sampler is now MCERTS certified meeting the Environment Agency's performance requirements. View downloads for certificate.
