I bought some of the reagents sold by ytterbium (those three listed above). They were well packaged and seem legit. I haven't had the chance to perform any chemical tests on them yet as I had a fairly busy weekend, but I have no reason to doubt they are what the bottles claim they are.
I'll try and get some tests done this week and report back if anything isn't right. But I'm sure it's all fine, ytterbium looked fairly trustworthy.

I'd be able to do a good deal for anyone interested in quite a few of these.
