I've just been going through this this week! We have a sample changer, and are
currently using Bruker's "blue" 5mm rotors; I think these sell for <$100 ea. These
rotors are a cheap polyethylene (or similar), and just a drop of chloroform will ruin
them. We've ruined a bunch in that way, so I need more, and I don't want the cheap blue
ones.
Bruker has Kel-F rotors for $135 ea.
Wilmad sells rototec 5mm PEEK spinners for $140 each ($120 for lots > 9). I bought a
couple of them recently to replace our Bruker ceramic rotors; rototec says they'll work
ok cold and hot, and they're much cheaper than the ceramic rotors, and more durable
(certainly will survive a drop, which the ceramic ones do not). They look good, but I
don't have much experience with them yet.
So I'm in a bind as to how to replace my sample changer spinners; I need 20 sometime in
the next year or so. But $120 ea is awfully pricey (even $90 ea would be a problem)!
We've tried to make some here in our shop, but so far I see too much spinning trouble
with the homemade stuff, where we aren't using the expensive materials like solid kel-f.
I think it's likely that I'll have to stick with vendor available rotors.

Expensive bits of plastic....
Direct from Bruker:
AH0130 (30 spinners) _at_ £53.13 (pounds sterling)
Z42516 (18 spinners) _at_ £62.33
>From rototec-spintec.com :
B-GFK-5 (one spinner) _at_ £64.00
WG-AH0130 (20 to 29) _at_ £45.00
WG-AH0130 (30 or more) _at_ £38.00
Some of these prices are about a year old and some spinners are not to be
used for high temperature work (whatever "high" means) so far the Rototec
(WG-AH-130) spinners are OK to 50'C.
