Masterflex C/L Dual-Channel Variable-Speed Compact Pumps

Contamination-free two-channel pumping in a compact format—ideal for analyzer, flow cell, and perfusion applications

Flow range: 0.002 to 12.3 mL/min per channel depending on drive rpm and tubing size

One- or two-channel, reversible pumping

Stackable, compact 1/4-DIN housing—mount in your equipment rack or place on your lab bench. (To mount, order brackets 77120-03 separately).

Separate single-turn speed control and cw/off/ccw switch with green LED power indicator—maintain speed setting when you turn pump on/off or reverse direction.

Reversible permanent magnet DC motor; purge fluid before or after pumping; pump fluid in either direction.

Remote control connections on back of pump; start/stop pump with a contact closure.

“Max” button runs pump at maximum rpm—prime or rapidly flush tubing.

Pump head is constructed from polyphenylene sulfide (PPS), stainless steel (SS), and features acetal co-polymer rollers. PPS and SS promote longer life and the six roller construction provides a low-pulsation flow.

Pump head has average fixed occlusion for tubing; no need to adjust occlusion when changing tubing.
