Masterflex® L/S® Precision Modular Drives with Benchtop Controller, Avantor®

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
Splash-resistant ABS plastic controller housing is IP33
rated
Remote control capabilities via a DB9 female connector on back of controller

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.

: Includes 6-ft (1.8-m) line cord with IEC 320/CEE22 socket. These models are shipped with country-specific plug/cord set; please specify ultimate destination when ordering.
