The lowest cryogenic temperatures achievable with liquid nitrogen systems are 77K. To lower temperatures further, it is necessary to use other systems. Helium cryostats can use this noble gas to cool a plate and reach temperatures of 4K. All these processes must be done in a vacuum since the air doesn’t allow the temperature.
