Positive displacement piston metering pump, 0.01–10 mL/min flow, 6000 psi max pressure, stepper motor drive.

The Eldex 5966 Optos 1SMP is a precision metering pump designed for accurate flow control at intermediate to high pressures. Key features include:

  • Flow Rate: 0.01 to 10 mL/min (theoretical max; depends on fluid properties)
  • Max Pressure: 6000 psi
  • Piston Diameter / Stroke: 1/8" diameter, 0.250" stroke
  • Construction Materials: Wetted parts in type 316 stainless steel, sapphire, ruby, graphite fiber reinforced PTFE, and CTFE
  • Reproducibility: Typically ±0.3%
  • Viscosity Limit: Capable of handling fluids up to 500 centipoise
  • Tubing Connections:
  • Inlet: 1/4"-28 low pressure plastic fitting compatible with 1/8" plastic tubing
  • Outlet: 10-32 tube nut and ferrule suitable for 1/16" tubing
  • Drive Mechanism: Reciprocating piston pumped by a stepper motor connected via an eccentric cam
  • Control: Advanced software adjusts motor speed by piston position for rapid intake and smooth delivery, minimizing pulsation
  • Remote Control Interfaces: Voltage (0–5 VDC), 4–20 mA current loop, RS232 serial communication

This pump is suited for applications demanding precise dosing under variable fluid conditions and high backpressures.

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.
