The Masterflex L/S Precision Variable-Speed Console Drive, 1–100 RPM, 115/230 VAC (7527-30) is a high-accuracy peristaltic pump drive engineered for precise fluid metering, chemical dosing, and sample transfer in laboratory and industrial environments. Delivering ±0.25% speed control accuracy and supporting up to four L/S pump heads simultaneously, it provides the repeatable flow regulation essential for demanding fluid handling workflows.
Product Features
- Speed range from 1 RPM to 100 RPM with ±0.25% speed control accuracy for precise fluid metering and repeatable flow rates
- Supports up to four Masterflex L/S pump heads on a single drive for multichannel operation or increased total flow output
- Three-digit LED display shows real-time motor RPM, allowing operators to verify speed settings at a glance
- Reversible motor enables bidirectional pumping, ideal for purging tubing lines before or after each run
- Separate speed and power (on/off) controls maintain your dialled-in speed setting when switching the pump on and off between batches
- Universal voltage input (90–260 VAC, 50/60 Hz) for operation on both 115V and 230V mains power worldwide
- Stackable, splash-resistant ABS plastic housing rated to IP33 saves bench space and withstands typical laboratory spills
- DB9 rear-panel connector for remote control of speed, direction, and start/stop via contact closure, open collector, footswitch, or handheld remote
- Compatible with nine L/S pump head types including Standard, Easy-Load, Easy-Load II, Easy-Load 3, High Performance, Cartridge, Multichannel, PTFE Tubing, and PTFE Diaphragm
- Built-in current-limiting safety circuit automatically shuts down the motor if incorrect tubing is loaded or the pump head is overloaded
Benefits
- Exceptional flow accuracy across the full 1–100 RPM range for reliable chemical dosing, reagent metering, and sample transfer
- Run up to four channels from a single compact drive, reducing equipment costs and bench footprint
- Contamination-free fluid path — peristaltic design ensures liquid only contacts the tubing, eliminating cross-contamination between runs
- Flexible integration into automated workflows through the DB9 remote I/O interface
- Worldwide power compatibility removes the need for external voltage converters across international facilities
- Durable, low-maintenance construction suited to continuous-duty laboratory and process applications
