Product description

Single-stage rotary vane oil-sealed vacuum pump driven by 3-phase motor, for non-corrosive gases.

The Agilent MS40+ 949-9225 is a single-stage rotary vane vacuum pump characterized by oil-sealed operation and driven by a three-phase electric motor. It is engineered for pumping non-corrosive gases under high vacuum conditions.

Key features include:

  • All fluid-contact parts are free of copper alloys, enhancing chemical compatibility.
  • Materials are selected to ensure extended operational life and reliability.
  • Design minimizes the number of gaskets, reducing maintenance frequency and complexity.
  • Easy disassembly and reassembly facilitate quick servicing.
  • Oil serves multiple functions: securing discharge valve sealing, lubricating internal parts, aiding heat dissipation, and noise reduction.
  • Equipped with a special anti-suckback device that:
  • Automatically isolates the vacuum system upon pump shutdown, preventing pressure rise and oil backflow.
  • Allows controlled air entry post-valve closure to keep oil from entering stator chambers.

This pump is optimal for applications requiring robust, maintenance-friendly vacuum creation without exposure to corrosive gases.

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.
