Deep-Sampling Lysimeter Collects Water Samples to 300 ft. Below Ground
This ceramic cup Deep-Sampling Lysimeter is excellent for vadose zone monitoring. The two-line, soil pore water collection device is designed for permanent installation down to 300' beneath the ground surface. Use with Vacuum Pressure Pump, No. 220695, sold separately. The vacuum is pulled and the vadose water flows into the ceramic cup. The pressure line is then used to push the sample to the surface.
This Deep-Sampling Lysimeter has a ball check valve that protects the porous chamber from the higher pressures required to retrieve the samples from greater depths. For very deep installations, a compressor may be necessary to provide sufficient pressure. A second ball check valve is installed in the sample line. Ceramic cup features pore size of 0.446μm. 400mL sampling capacity. Measures 1.9" O.D. x 27"L.
