Masterflex® L/S® Digital Modular Dispensing Pump Systems, Avantor®

Precision digital drives offer three dispensing modes and precision low-maintenance motors— modular format lets you place motor and controller where convenient.

• Digital interface with graphical LCD shows pump performance and operating mode— continuous run, timed dispense, copy dispense, or volume dispense
• Remote control available using analog communication—voltage, current and contact closure
• Select your preferred language from the user-friendly menu for programming and operation
• Dispense by Volume in ml (0.001 to 9,999 mL), L, or gal; Copy—1 to 9,999 dispense cycles; or Time—time interval of on/off cycles (1 sec to 99 hr, 59 min, 59 sec per cycle)
• Antidrip function ensures dispensing accuracy
• Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio
• Reversible motor—purge tubing before or after pumping or pump fluid in either direction
• Powerful motors let you stack pump heads for increased flow rates and for multichannel applications

These precision drives feature a programmable dispense interval that lets you set the delay between dispense cycles for convenient, automated dispensing by time or by volume. Precise PWM speed control (±0.1%) maximizes accuracy and efficiency while the brushless motor gives you quiet, maintenance-free reliability. Programmed calibration ensures dispense and display accuracy—drive stores one calibration value per tubing size. Program the drive via the simple membrane keypad; keypad lock/unlock feature protects settings.
