Cole-Parmer Masterflex L/S Easy-Load II Pump Head with 2-Channels for Precision Pump Tubing

Masterflex L/S Easy-Load II Pump Head with 2-Channels for Precision Pump Tubing, PPS Housing, CRS RotorMasterflex L/S® Easy-Load® II Pump Head with 2-Channels for Precision Pump Tubing, PPS Housing, CRS Rotor

No need to stack heads—get two channels in one head

• 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
• Compact design for efficient use of space
• Suitable for use with L/S® Precision pump tubing sizes
• Rotor is constructed of cold-rolled steel (CRS) for better chemical resistance

More About this Item

The two-channel pump head lets you pump two synchronous flow channels, proper retention requires the use of the same size tubing in each channel. These pump heads accept the six L/S® precision tubing sizes L/S® 13, L/S® 14, L/S® 16, and L/S® 25. Achieve flow rates of 0.06 to 1000 mL/min—flow rate depends on drive rpm and tubing size.
