## Description

The Micro Double Valve Pumps (Micro DVP) have a remarkably small and flexible design. As a positive displacement pneumatic pump, it uses coaxial PTFE tubing to give high quality samples. It is small enough to fit in 1/2" (13 mm) tubing and all channels of the Solinst Model 403 CMT Systems, as its diameter is only 3/8" (10 mm). A manifold at the top end of the pump has a 3/16" (5 mm) PTFE sample tube and a quick-connect fitting for easy attachment to a Control Unit. A multi-purge sampling head is also available for use with the CMT System.
