Laboratory peristaltic pump Masterflex® L/S® EW-77923

Precision digital drives offer three dispensing modes and precision low-maintenance motors— modular format lets you place motor and controller where convenient Flow rate 0.0012 to 3400 mL/min with L/S tubing. Flow rate depends on drive rpm and tubing size. Graphical LCD shows four operating modes continuous run, timed dispense, copy dispense, volume dispense. View pump performance continually. Menu-driven interface lets you select one of seven languages for programming and operation Dispense by mL—volume in mL of each dispense, 0.001 to 9999 mL; Copy—1 to 9,999 dispense cycles; or SEC—time interval between each dispense cycle (1 to 9,999 secs) Reversible motor—purge tubing before or after pumping; pump fluid in either direction Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio Powerful motors let you stack 2 pump heads for increased flow rates and for multichannel applications Remote control capabilities – Speed control input scalable 0 to 20 mA, 4 to 20 mA, or 0 to 10 V – Pumping direction requires open collector or contact closure – Start/stop/purge requires open collector or contact closure – Tachometer output scalable 0 to 20 mA, 4 to 20 mA, 0 to 10 V, open collector
