Jar Tester. A four-jar tester using 1-Liter round beakers were used for nearly all field and laboratory studies. Most source waters were collected at the plant and transported back for laboratory jar testing. The benefits in using 1-liter round jars over 2-liter squared jars are (1) 50 percent less water required for a set of jar testing, (2)
