The 408M Micro Double Valve Pump has a remarkably small and flexible design. It is a pneumatic pump similar to a Bladder Pump, but using coaxial Teflon tubing with stainless steel valves & filter for high quality sampling.

It is small enough to fit in 1/2" (13 mm) tubing and all channels of the Solinst CMT System. The Micro DVP is ideal for low flow sampling in narrow applications and operates to depths of up to 200 ft (60 m). A flow rate of 20 – 200 ml/min can be obtained.
