What Bert said. $2589.65 is a lot for a Kel-F spinner.

I would ask the Bruker sales rep to lower the price.

Hi Anne,
just some 0.02 EUR (partially nitpicking…):
- it’s cortecnet.com (not cortec.net, easy to confuse)
- both POM and Kel-F are essentially „room-temperature“ spinners
(Kel-F going 20 degrees lower & higher than POM) whereas only PEEK and ceramics
offer the full -150…200 C VT range.
I myself used some Kel-F solids MAS turbines long time ago and they definitely
started softening in the 50-60 deg C range…
- are you sure you compare the correct prices (I can’t believe Bruker
sells RT-spinners for $2500 apiece)?
Cheers
Bert

I have a set of tan 5mm PEEK VT spinners from
http://www.rototec-spintec.co
The temperature range is -150C to +200C. They have worked well over many
years and are much lighter than the heavy ceramic VT spinners and it is much
easier to insert the a NMR tube.
The part number appears to be B-PEEK-5 and cost is 487.19 Euro.
