The entire lab supply industry is disgusting in this respect. The funding (and recent grants) that a given professor or research lab has is generally publicly available information that vendors will buy in easily digestible formats from brokers and companies that scrape the websites of major granting agencies.

All of their products, however realistically commoditized, will require a drawn out engagement with a rep who knows how much money you’ve received recently and even has an outline what research you plan to do over the next few years since even the detailed applications often get published alongside funding allocations.

The exact same piece of equipment, consumables required to use it, and service agreements might be anywhere from X to 10X depending on what they (as a result of asymmetrically available knowledge) know you need and how much you could theoretically spend.
