How do I buy liquidated lab instruments?

I’m an assistant professor running an academic lab in a location with many life sciences companies, and I just know that there are pallets full of high-end lab equipment being liquidated for pennies on the dollar as things go boom and bust over the normal course of things.

I want to score some instruments on the cheap for my lab and am willing to put in the legwork to monitor auction websites and local warehouses, but I don’t know where to start looking. Does anyone know good websites for this? Types of establishments I can seek out locally? Search terms, even?

Note: I already know about my state government’s surplus warehouse. I’m more interested in private industry.
