We recently upgraded the FTS cooling system of the I500 to a high-capacity model (the same model as the I400 has). Users now can do low temperature experiments on the 500 down to -55 °C without the need of liquid nitrogen.
Please always make sure the currently installed probe as well as the solvent of your samples can handle the temperature you’re going to set. And, remember to use set_temp command to accurately set the temperature (see the previous post). Talk to the NMR staff if you have questions or need help.
