Ideal for sample retrieval from shallow water levels less than 30ft (9m).
Mini Inertial Pump
Mechanical pump used inside 1/4 LDPE tubing. Typical flow rates of 50 to 250mL/min. If your sites water level is deeper than 50ft (15m), Teflon tubing is recommended
Small and flexible design makes this gas drive pump ideal for delivering high quality samples, in combination with the Model 466 Electronic Control Unit. Flow rates of 20 to 150mL/min make the 408M suitable for low flow sampling applications. Constructed of Stainless Steel and LDPE for lengths less than 50ft (15m) and Teflon tubing for any depths up to 200ft (60m) applications. This is the only viable option in wells with depth to water over 150 ft.
For flowing conditions or vapor monitoring, Solinst offers a monitoring assembly, which applies a pressure seal to the individual CMT channel. This facilitates sampling through the well head at the surface.
