,
Rinses transistors, diodes, a n d other small components in hot, ultra pure water. Builtin purification system continually repurifies the water by (1) removal of organic impurities (2) demineralization and (3) filtration of submicroscopic particles to 0.45 micron . . for final rinse water of 18,000,000 ohms electrical resistance, free of organic impurities and particulate mat ter. Available in several sizes Write for Bulletin #146-A.
Barnstead Two-Bed Demineralizers are built to give many years of trouble-free service. Col umns are mounted on heavy steel frame with skid base and come complete with all piping and valves, ready for operation. Illustrated Model TM-6 with flow rate of 2000 g.p.h.
