The Significance of Ultra-Low Temperature Storage

When you want to preserve biological samples and cell viability it is critical that cell metabolism be slowed or suspended entirely. Colder is usually better. Many facilities use protocols for storing specimens at temperatures of -70°C or -80°C. In some cases, specimens are preserved in liquid nitrogen (LN2) in the liquid phase at -196°C, or in the vapor phase within a range of -196°C to -120°C or warmer, depending on the vapor phase gradient.
