L/S Easy-Load II Pump Heads for High-Performance Precision Tubing 

Automatic retention holds tubing securely in place with no manual adjustment—just load the tubing and start the pump

• Four-roller rotor improves pressure performance and mechanical stability while reducing pulsation.
• Improved occlusion bed geometry lengthens tubing life.
• Polyphenylene sulfide (PPS) housing with either stainless steel (SS) or cold-rolled steel (CRS) rotor—choose CRS for economy or SS for greater durability and chemical resistance.
• Model 77201-62 with adjustable occlusion gives you the option of loosening occlusion for longer tubing life or increasing occlusion for higher pressure.
• Each pump head for high-performance precision pump tubing accepts tubing sizes L/S® 15, L/S® 24, L/S® 35, and L/S® 36. Achieve flow rates of 1.7 to 2900 mL/min (1 to 600 rpm).

These pump heads accept the four high-performance precision tubing sizes. High-performance precision tubing has a thicker wall than precision tubing enabling better pressure generation, greater suction lift, and greater ability to pump viscous fluids.
What's included: single-channel mounting hardware and a 15'' (38-cm) length of silicone pump tubing. For stacking multiple heads (up to the specified limits of your drive) order two- three- or four-channel hardware separately.
