The Micro DVP is ideal for low flow sampling and narrow down-hole applications.
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.
