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.

GC and GC-MS systems tend to sit in service far longer than their owners expect, which means a decommissioned unit is often further from obsolete than the internal paperwork suggests.

Common questions

Do you buy the GC separately from the MSD?

Yes, either separately or together. A complete system usually nets more, so it is worth asking before splitting one up.

How old is too old?

There is no fixed cut-off. Send the model number and we will tell you plainly whether there is a market for it.

What about consumables and spares?

Send the list. Inlets, detectors and spares often travel with a system and add to the offer.

Who moves it?

We do. De-installation, crating and insured freight are handled by our team.

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.
