The Avance III 300 instrument is equipped with a 5 mm BBFO probe, which can be tuned from 97Mo to 19F. The probe has a z‐gradient. An autosampler (24 position NMR Case) is available for larger sample volumes or overnight runs.
The 300 MHz instrument is equipped with a variable temperature controller using a liquid nitrogen evaporator for low temperatures.
Variable temperature experiments can be run, taking probe limitations into account. The sample temperature range for BBFO probes from −120°C to +150°C is not to be exceeded. For experiments exceeding the temperature limits of plastic spinners (−50°C to +50°C), ceramic spinners must be used.
