Instrumentation in the NMR Core
Below is a summary of the NMR instruments. We have 5 Bruker AV III systems running Topspin 3.6 or 3.7.
The NMR rates for Columbia and other academic users are as follows:
All NMR instruments (300 MHz, 400 MHz, 400 MHz SL, 500 MHz) are $20/hr except the 500 MHz Ascend with cryoprobe which is 3x or $60/hr for FY26. Rates are updated every fiscal year. FY26 rates are lower than previous years due to a grant from the CU Research Stabilization Fund.

Notes:
1. The 400 has an 1H optimized probes. All others are X optimized including the BB cryoprobe on the 500 Ascend.
2. 19F observation is possible only on 300, 400SL, 500, and 500 Ascend. Ask about 2H observation.
3. The 400SL, funded by an NSF CRIF grant, is controllable from remote locations using either Iconnmr or standard Topspin software.
4. Variable temperature range for all probes is -100 C to + 150 C, except for the Cryoprobe which is 0-135 C.
