Many times the process in various plants is the same, but how it is achieved is different, because you have different equipment, different people, different plant floor layouts, and different timing, among other things. For example, making paper cups involves taking a roll of paper that’s got a plastic extrusion coating on it, printing a layout on the paper, punching out the cups according to the layout, and then putting them into a machine that forms them into cups. Then they’re stuffed into bags and the bags are put into a box — maybe six steps in all. But you have four plants that do that same process in about six different ways. Sometimes it’s all done on a single machine. There’s a roll of paper at one end and boxes of cups at the other end. At a different plant, one machine prints the layout, but then the printed sheets are stored in a warehouse temporarily before they’re put into the next machine, which punches them. The entire process might be done in such piecemeal fashion, so the way a new software system gets used will be different in this case.

Lysimeters are used for the collection of in situ soil water; they include suction and pan-type lysimeters. A typical suction lysimeter consists of a porous cup, a PVC sample accumulation chamber, and sampling and air tubes (Figure 10-5). The cups are usually comprised of a hydrophilic material such as ceramic or an aluminum oxide (alundum), or polytetrafluorethylene, which is hydrophobic. During installation, the porous cup is enveloped by silica flour to prevent plugging and maintain sufficient vacuum (i.e., 10 centibars). The flexible sampling tube terminates at the bottom of the lysimeter. The air tube terminates immediately below the top of the sample accumulation chamber.

Each side of the chamber is then filled with an electrolyte solution of the user’s choice, and electrical contact to Ag/AgCl electrodes is made via salt bridges (Figure 15.18; see Practical Tips 15.1). Chambers and cups are sold commercially; the reservoirs usually come in sizes from 1 to 3 mL. The cups can be made of different materials, such as polystyrene, polysulfone, or Delrin. We recommend commercial cups and chambers rather than trying to make homemade bilayer orifices. All of the sizes and materials sold work well, and the author does not have any strong preferences, though some electrophysiologists prefer cups of one material or another.

For the investigations, plastic cups were produced by GIZEH Verpackungen GmbH & Co. KG, Germany in a thermoforming process using PP virgin material and PCR material. PCR polypropylene granulate Systalen PP-C14900 gr000 was provided by DSD – Duales System Holding GmbH & Co. KG, Germany. Both the virgin and the PCR cups have approximately the geometric shape of a truncated circular cone with a full rim volume of VRV = 214 cm3 and a nominal volume of VN = 160 cm3 (see Figure 1).
