Solinst Model 408M Micro Double Valve Pump PN:108220

The Micro 408M 90ft PTFE Assembly pump, tubing & manifold DVP is ideal for low flow sampling and narrow down-hole applications. Flow rates of 20 to 150 ml/min, are obtained, with very small associated purge volumes from within the narrow applications. The Micro DVP is durable and easy to operate using the pre-sets and fine tubing capabilities built into the Solinst Model 466 Electronic Control Unit. APPLICATIONS Groundwater sampling in: CMT and Waterloo Multilevel Systems Direct-Push/Drive-Points Low flow monitoring in narrow diameters   DESIGN AND CONSTRUCTION The Micro DVP uses coaxial PTFE tubing in lengths of 50’, 100’, 150’ and 200’ (15 m, 30 m, 50 m and 60 m). The 50 ft. (15 m) pump is also available with LDPE outer drive tube and a PTFE inner tube. The pump body and filter is 6” x 3/8” (150 x 10 mm). It is constructed of coaxial PTFE tubing with stainless steel fittings and a 100 mesh stainless steel filter. Filters are easily cleaned and replaced. A manifold at the
