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.
