FAQ
1. How do I decide which 400 to use?
The capabilities of the two 400 MHz spectrometers are detailed in this chart.
2. Does it matter which NMR tube I use?
Only if you care about sensitivity and/or running variable temperature experiments. Here is a comparison of different tubes:
For quick and dirty spectra, any of these tubes will work but it is clear that if you are sample limited and want an excellent S/N you should use a better quality tube. (Generally, better quality tubes are more expensive and will not be labeled "high throughput".)
If you want to do variable temperature experiments, it's important to use a good quality tube (Type 1, class A) so that it doesn't break as a result of temperature changes. The only tube shown above that is suitable is the Wilmad 528.
