ACQUAINT YOURSELF WITH THE PARTS <br />The Pressure-Vacuum Soil Water Sampler (Model 1920F1) comes <br />fully assembled. The Pressure-Vacuum Soil Water Sampler (see <br />Figure 3) is constructed of a 1.9 inch O.D. PVC tube (made ofFDA- <br />approved material) with a 2 bar porous ceramic cup bonded to one <br />end. The serviceable end of the Sampler is completely sealed and <br />two i/4-inch tube connectors protrude from the top. The white tube <br />connector indicates the "Pressure/Vacuum" side and is used exclu- <br />sively for pressurizing and evacuating the Sampler. The green tube <br />connector is used to recover the collected sample. <br />Two 1/4-inch O.D, polyethylene access tubes are used for pressur- <br />izing and recovering samples which are terminated in neoprene <br />tubing. Clamping rings are used to clamp the neoprene to keep <br />the Sampler under negative pressure (not shown here). <br />TOP VIEW OF SAMPLER <br />~\ <br />PVC Tube (1.9 inch O.D.) <br />\Sample Recovery Side <br />Side (Green) <br /> <br />Dip Tube (inside sampler) <br />Standard 2 Bar <br />Porous Ceramic Cup <br />Figure 3.
