The Cole-Parmer Masterflex L/S Brushless Variable-speed Digital Drive Model 7523-60 comes with an accurate digital pump drive for critical metering and dispensing applications.

  • Flow rate: 0.6 to 3400 mL/min; flow rate depends on drive rpm and tubing size. Achieve lower flow rates with cartridge or multichannel heads and microbore tubing.
  • Maintenance-free reversible motor with precise PWM speed control—no brushes to replace and quiet, efficient operation.
  • Dispense interval mode lets you set time delay between dispense cycles—program delay from 1 to 9999 seconds.
  • Four digit LED display shows four different parameters: motor rpm, flow rate, dispense volume, and copy number. View pump performance continually.
  • Dispense by: mL—vol in mL of each dispense; 0.001 to 9999 mL; Copy—1 to 9,999 dispense cycles; or SEC—time between each dispense:1 to 9,999 secs.
  • Membrane keypad for easy programming—select tubing size and enter desired flowrate; drive locks in required rpm. Keypad lock/unlock feature prevents accidents or tampering.
  • Drive stores one calibration value per tubing size—calibrate drive to maximize accuracy
  • Remote control capabilities via DB15 female connector on back of drive. Speed control input: 0 to 20 mA, 4 to 20 mA, or 0 to 10V; Pumping direction: requires open collector or contact closure; Start/stop/purge: requires open collector or contact closure. Tachometer output: 0 to 20 mA, 4 to 20 mA, 0 to 10V, or TTL pulse;
  • Tachometer feedback for ±0.25% speed control. Dispense or meter with accuracy and precision.
