Solinst 404 Series Inertial Manual Sampling Pump w/ 1"-Dia Foot Valve‚ Plastic Delrin‚ D25

This economical‚ manually-operated inertial pump offers an easy sampling option for groundwater monitoring. The unit features just two components: a section of riser tubing and a one-way foot valve that’s inserted into the tubing by hand. A simple pumping motion brings a steady flow of water up to the surface through the tubing.

Tubing and foot valves come in a range of sizes suitable for most well diameters and sampling applications. Order foot valve and corresponding tubing separately. Optional in-line disposable filters are also available.
