Cole Parmer Masterflex L/S Digital Variable Speed Peristaltic Pump with Reversible Flow

The Cole Parmer Masterflex L/S Peristaltic Pump features a rugged stainless-steel housing rated NEMA4 (IP66) for reliable and easy washdown in laboratory environments. Equipped with a 0.1 HP brushless motor capable of speeds ranging from 0.1 to 600 rpm, it delivers precise flow rates between 0.006 and 3400 mL/min, depending on the installed pump head and tubing configuration. This pump supports multiple pump heads including Standard, Easy-Load, Easy-Load II, Easy-Load 3, High Performance, Cartridge, Multichannel, PTFE Tubing, PTFE Diaphragm, and Cytoflow variants, allowing extensive flexibility for diverse bioprocessing needs and molecular diagnostics workflows.

The digital variable speed drive offers intuitive controls via membrane keys with a digital display for setting speed, direction, and operation mode. Available modes include continuous run, timed dispense (up to 99 hrs 59 min 59 sec per cycle), copy dispense (up to 9,999 cycles), and volume dispense, facilitating complex fluid handling essential in biotechnology, synthetic biology, and clinical diagnostics applications.

Additional features include reversible pump action, anti-drip functionality to enhance dispensing accuracy, and dual voltage compatibility (115/230V, 50/60Hz). Its compact footprint (9 x 17 x 10 inches) and 23 lbs weight make it suitable for benchtop use in cell culture bioprocessing, live-cell imaging preparations, and other laboratory protocols requiring sterile fluid transfer.

This peristaltic pump is widely adopted in biopharmaceutical production pipelines and molecular cloning workflows for reliable, contamination-free fluid delivery. Compatible with various tubing materials and pump heads, it provides versatile performance critical in research fields such as biotechnology, biomedical engineering, and molecular biology.
