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

• New design and automatic tubing retention allow for multiple tubing sizes—change tubing without removing head from drive
• Four-roller rotor improves pressure performance and mechanical stability while reducing pulsation
• Model available with integrated open-head sensor–connects directly to sensor-equipped drives
• Pump heads are stackable for multichannel applications
• Compact design for efficient use of space
• Suitable for use with L/S® Precision pump tubing sizes

These pump heads accept the six L/S® precision tubing sizes. For stacking multiple heads (up to the specified limits of your drive) order two- three- or four-channel hardware separately under "Accessories". When two Easy-Load® II pump heads are stacked rollers are offset by 45°--combine the outlets from two stacked heads for a 95% reduction in flow pulsation.
