Lab equipment auction review

 

When “Auction Bargain” Turns Into a Headache — Why Buying a Refurbished Incubator from American Instrument Exchange Just Makes Sense

In the world of lab management, stretching a budget can feel like a full-time job. For many labs—especially startups, small research teams, or academic departments—buying used equipment from auctions or third-party sellers can seem like a smart move.

With a long-standing reputation for high-quality refurbished lab equipment, and a specialty in incubators from brands like Thermo, VWR, and Binder, she gave them a call.

“The difference was night and day. The staff was incredibly knowledgeable. They knew the model I needed and had one in stock that had been refurbished and tested. Plus, it came with a warranty.”

Better Than New?

She was surprised not only by the performance of the unit she received but also its appearance.

“When I unpacked it, I honestly thought they had sent me a new incubator. It was spotless. Every surface had been scrubbed and polished. Even the interior shelves looked unused.”

And the kicker? The total cost—including shipping—was only slightly more than what she had paid for the broken unit at auction.

“If I had gone with American Instrument Exchange from the start, I would’ve saved myself the cost of diagnostics, weeks of downtime, and a lot of frustration.”

Why Buying Refurbished from American Instrument Exchange Is the Smart Choice

✅ Fully tested and verified: Every incubator is inspected, cleaned, and performance-tested by skilled technicians.
