Masterflex® L/S® Precision Variable-Speed Modular Pump Systems, Avantor®

: Avantor Fluid Handling

Place where convenient—ideal for limited spaces, hoods, or isolation chambers.

Flow rate 0.06 to 3400 ml/min with L/S tubing—flow rate depends on drive rpm and tubing size
Three digit LED display shows motor rpm — confirm speed setting at a glance
Reversible motor—purge tubing before or after pumping; pump fluid in either direction
LED indicators confirm motor direction
Choose between benchtop controller or washdown wall-mount controller drives

L/S® modular drives feature reversible pumping and allow you the flexibility to separate the motor from the controller. These accurate modular drives have powerful motors, speed display, and ±0.25% speed control for precise flow regulation—ideal for metering applications.

Benchtop controller drives feature a splash-resistant ABS plastic controller housing with IP33 rating and remote control capabilities via a DB9 female connector on back of controller. Wall-mount controller housing is powder-coated aluminum and IP66/NEMA 4X rated for washdown with remote control capabilities via weather-resistant connection on controller.
