Masterflex C/L Dual-Channel Variable-Speed Tubing Pump; 10 to 60 rpm, 115/230 VAC

EW-77120-42
$605.00 USD/EACH

  • 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.

C/L pumps are compact (1⁄4 DIN) and perfect for low-flow OEM use or analyzer applications. These easy-to-use, economical pumps feature reversible pumping, remote control capabilities, and rapid tubing changes. Ideal for consistent fluid delivery in chromatography, spectroscopy, and dispensing applications.
Maximum suction lift of 5 ft (1.5 m); max discharge head of 20 ft (6.1 m); max pressure 15 psi (1.0 bar). Selfpriming pumps withstand minor back pressure.What's included: 5 ft (1.5 m) of 0.89-mm ID Tygon LFL tubing and dual-voltage (115/230 VAC) power supply with 6-ft (1.8-m) power cord.
