Sell support equipment

The gear around the instrument has a market of its own. Nitrogen generators, autosamplers and detectors are all live parts of somebody else’s system.

What we buy in this category

Gas generators Nitrogen generators and the supply gear around a mass spectrometer.
Autosamplers Vial and plate handling, standalone or from a broken-up stack.
Detectors Diode array and other chromatography detectors.
Workstations and software Where the licence position allows it. Tell us what you hold.
Condition Working, in need of service, or as-is.

Two ways to work with us

Pick whichever gives you the cleaner recovery on a given asset. We will tell you honestly which one that is.

Sell outright We buy the instrument directly. A firm offer and payment on pickup, with no waiting for a buyer and no marketing on your end.
Consignment You keep title until it sells. We photograph, verify, list and market it through our buyer network, then take a margin. Usually a higher net than auction.
Off-lease remarketing For lessors and dealers with returned or repossessed units: a turnkey channel that de-installs, verifies and sells.

How it runs

  1. Tell us what you have Model number, and photographs if you have them. A configuration list if you do not.
  2. We review it Priced by people who have serviced these platforms in the field, against what the system is actually worth today.
  3. A firm offer Within two business days of review. Outright purchase, or consignment if that nets you more.
  4. We handle the logistics De-installation, crating and insured freight by our team. Nothing lands on yours.

Why sell here

An instrument is worth what someone who understands it will pay. Our bench has serviced these platforms in the field, so a valuation here is a technical judgement rather than a guess against a catalogue price.

Auction is the usual alternative and it is rarely the better one. It sets no floor, it costs you the logistics, and it prices a system that nobody has verified. We handle de-installation, verification and freight, and typically return more with none of that landing on your team.

This is the category most likely to be thrown away. A working nitrogen generator has real value and a thin used market, which means the few that come up move quickly.

Common questions

Is a used nitrogen generator worth anything?

Yes, and the used market for them is thin, which tends to work in a seller’s favour. Send the model and hours if you have them.

Can I sell software or a workstation licence?

Sometimes. Whether a licence can transfer depends on the specific agreement, so tell us what you hold and we will establish the position before quoting.

Is there a minimum?

No. If you are not sure something is worth listing, send the model number and we will tell you.

Do you collect small items?

Yes, usually alongside a larger collection. If it is on its own we will tell you honestly whether the freight makes sense.

Send a model number to start

A model number and a photograph are enough for a first read. Serial numbers and a configuration list speed the offer up.
