More About this Item

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). Self-priming pumps withstand minor back pressure.

What's included: 5 ft (1.5 m) of 0.89-mm ID Tygon® LFL tubing and a dual-voltage (115/230 VAC) power supply with 6-ft (1.8-m) power cord. Pumps are shipped with cord/plug assembly appropriate to destination country. Order additional microbore tubing based on chemical compatibility and flow rate.

Comments about Masterflex C/L Variable-Speed Tubing Pump; 1.7 to 10 rpm, 115/230 VAC:

The new C/L pumps are poorly assembled, out of three pumps two had assembly issue and all three pinched the tubing so tight it stretched the tubing causing drastic volume swings. Had to machine the clamp to reduce the interferrence fit when using the reccommened tubing.

  • Q:

    Does this pump have a pulse dampener? Is purging possible with this pump?
    Asked on 10/6/2011 by Anonymous

    • Staff Reviewer

      A:

      The "Max" button is generally used for priming or purging.
      We do not have a specific pulse dampener for this system, but we may be able to adapt the 07596-20 to fit microbore tubing. Please call for further assistance.

  • Q:

    how we can calibrate the pump?

      A:

      This pump does not have a calibration function. However you could adjust the flowrate based on expected output. After letting the tubing warm up for about 20 minutes. Time and measure the volume obtained, you may adjust the speed of the pump (via a potentiometer) to get closer to what you need.
