Product description

Analog peristaltic pump drive with 8-roller cartridge head, ±2% speed control, 0.00005–350 mL/min flow rate.

The Cole-Parmer Masterflex 7520-35 is an analog peristaltic pump drive featuring:

  • 1/10-HP reversible motor with soft start and back EMF, providing ±2% speed control
  • Separate single-turn speed control and on/off/reverse switch with inertia center
  • Green LED power indicator allowing maintenance of speed settings when toggling power
  • Suitable for precise metering applications

The included 7519-00 cartridge pump head is an 8-roller version providing reduced pulsation for lower flow rates:

  • Precision-molded housing with fast tubing changes through cartridge snap-in/out design
  • Accepts 4 or 12 small cartridges for synchronous multichannel pumping
  • Flow rate range: 0.00005 to 350 mL/min, with up to 600 rpm
  • Adjustable occlusion tailored to tubing size
  • Compatible with 2-stop microbore tubing or Masterflex L/S tubing sizes 14, 16, 25, 17 (tubing not included)

Additional notes:

  • To further reduce pulsation, cartridges can be mounted in opposite directions and connected by a Y-connector for flow balancing
  • Pump heads can be added, removed, or substituted depending on inventory availability; contact supplier for pricing and options
  • For detailed operation and specifications, see linked pump manuals.

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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
