Average LN2 Usage

This article discusses the factors influencing the average liquid nitrogen (LN2) usage in a 7452 CryoMed freezer during a profile run. Key variables include valve size, tank pressure, valve core wear resistance, environmental conditions, sample volume, and solenoid openings. On average, 15 to 20 liters of LN2 are used per run, depending on "wait" and "hold" times. This information is crucial for determining the appropriate supply tank size.
