Model 408M Micro Double Valve Pump

Model 408M Micro Double Valve Pump

The 408M Micro Double Valve Pump has a remarkably small and flexible design. It is a pneumatic pump that uses coaxial PTFE tubing to give high-quality samples. At 3/8" (10 mm) diameter, it is small enough to fit in 1/2" (13 mm) ID tubing such as in Waterloo Multilevel System 5/8" open tubes, as well as channels of the Solinst Model 403 CMT Multilevel Systems. Ideal for low-flow groundwater monitoring in narrow applications.
