American Instrument Exchange buys and sells used laboratory and scientific equipment.

Our surplus lab equipment is reconditioned for many types of laboratories, including biomedical, medical research, chemical, major pharmaceutical companies, rock-star biotech startups, and university and hospital research laboratories. In addition, we continue to be the preferred supplier for used and refurbished equipment to customers worldwide in a variety of other industries as well, including major breweries and microbreweries, cannabis startups, academic labs, and more. Despite the global network of customers, we have built over the past five decades a significant portion of our business is still centered in and around the biotech cluster in Cambridge and Boston that we call home.

So if you’re in and around Cambridge and Boston and you’re in the market for used and refurbished lab equipment, give us a call or email. But if you’re not local, that’s fine too: we utilize a huge network of freight carriers in order to quickly and safely ship lab equipment across the USA and around the world.
