Product description

Digital variable speed Masterflex L/S peristaltic pump with 0.1 HP motor, 0.006–3400 mL/min flow, reversible action

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.

Key specifications:

  • Motor: 0.1 HP brushless
  • Speed range: 0.1–600 rpm
  • Flow rate: 0.006–3400 mL/min (dependent on tubing and pump head)
  • Housing: Stainless steel, NEMA4 (IP66) rated
  • Control: Digital variable speed with multiple operation modes
  • Reversible pump action
  • Dimensions: 9 x 17 x 10 inches
  • Weight: 23 lbs
  • Electrical: 115/230 V, 50/60 Hz

This robust peristaltic pump offers essential functionality for bioprocessing tasks requiring precise, contamination-free fluid handling and is a preferred choice for continuous and batch dispensing in molecular diagnostics and synthetic biology labs.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
