Masterflex C/L Dual-Channel Variable-Speed Peristaltic Tubing Pump, model 77120-50
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.
Note the 12V power supply is not included. If required this can be supplied by Cole Parmer as per following link
