PURE LATEX TUBING This photo, taken during extra corporal heart surgery, shows the use of a Sigmamotor Pump. It utilizes a peristaltic-like action for handling liquids, slurries or gases. It was chosen for this delicate operation because it cannot contaminate blood. In contact only with pure RLP Latex Tubing, the blood never touches working parts of the pump. RLP Latex Tubing is used as the conductor in these pumps because of its purity and resiliency. Only RLP can recover fast enough from the pulsating action to provide safe and efficient operation. These qualities, along with its strength, lightness, gripping power, flexibility and chem ical resistance, give RLP Latex Tub ing countless laboratory and produc tion applications. Economical too — it can be repeatedly sterilized and re-used. A v a i l a b l e in 24 standard sizes. Photo courtesy of The University of Minnesota Variety Club Heart Hospital, Minneapolis
