LN2 Storage & Dewars

LN2, a transparent liquid with a density of 0.8, rests at 77 Kelvin under normal pressure (-320°F or -196°C). Vaporization demands 160 kJ/liter, so 1 watt yields around 23cc LN2 hourly evaporation. Efficient storage depends on various-sized vacuum insulated Dewars, though perfect insulation is unattainable, causing continuous evaporation. This results in substantial 696:1 gas production relative to liquid volume. Opt for modern cryogenic storage vessels to reduce pressure buildup risks.
