I purchased this diffusion pump off of ebay for $100 but I can't find anything about the flange on the top. Could anybody identify it and point me in the direction of an adapter? Thanks.

Looks like ISO-B63. Right diameter, right number of holes, and ISO.

As far as an adapter goes, you can search ebay, but I've found ldsvacuum is still often cheaper than a lot of the used stuff on ebay for some reason- at least as far as high vacuum fittings go.
Ebay listing says the pump was sold for $400 though?

If your experiment needs statistics, you ought to have done a better experiment.

I made a best offer, and i found when that happens it doesn't show the sell price. It was originally listen for $400 but the "Best Offer" was $100. Thank you for the flange though.

Apparently the heater and fan works. Looks clean and complete. Looks like you did well for $100.
