Edwards nEXT400D - ISO160 160W Turbomolecular Pump

Ultimate Vacuum 1x10-8 mbar Inlet Connection DN160ISO-K Pumping Speed Nominal 24,000.00 l/min

Features

  • Combines oil-lubricated ceramic lower bearing with a dry permanent magnetic upper bearing for enhanced performance
  • Features built-in electronics for easy integration with TAG and TIC controllers
  • Allows for in-field oil and bearing cartridge changes with minimal tools
  • Provides high speeds and compression with advanced simulation-derived designs
  • Features a patented bearing suspension system to minimize noise and vibration
  • Ensures a clean vacuum with a permanent magnet upper bearing
  • Suitable for research, high-energy physics, mass spectrometry, and industrial applications
  • Designed for long-term reliability and minimal maintenance needs

nEXT turbomolecular pumps are hybrid bearing pumps with integrated controllers for pumping speeds from 47 to 1250 ls-1.The nEXT is a hybrid bearing compound turbomolecular pump. nEXT pumps combine our proven bearing technology (oil lubricated ceramic lower bearing with dry permanent magnetic upper bearing), an improved rotor design with a new molecular drag stage to deliver improved pumping speed and compression ratios, and user serviceability. They feature 24 V to 48 V DC sensorless motors with a built-in drive that is fully compatible with our range of TAG and TIC controllers.Features and Benefits

  • Upper magnetic bearing - ensures clean vacuum, low power and low vibration.
  • Optimised rotor designs - deliver high speeds and high compression.
  • Range of variants suitable for many applications - D = standard nEXT pump variant, H = optimised rotor design for high light gas compression and T = additional regenerative stage for increased compression and higher backing pressure capability
  • Integrated controller / electronics - offers direct I/O or serial control or can be connected to one of our TAG or TIC controllers for easy systemisation.
  • Fully user serviceable - oil cartridge and bearings can be changed in the field with minimal tooling.
  • Inlet screen - supplied as standard

INCLUDED: The Edwards nEXT400D - ISO160 160W Turbomolecular Pump includes:

  • Power Cord
  • One Year Manufacturer's Warranty

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.
