CL/CLPB Series Dewars. This line of portable cryogenic tanks is designed for low-pressure transport and storage with conventional straight liquid dispensing. It is an ideal liquid nitrogen tank that also works well with liquid argon or liquid oxygen.
understanding of the hazards associated with handling liquid nitrogen. Our intention is to provide a complete package of instructions to enable the liquid nitrogen Dewar and associated equipment to be used simply and safely in different applications. It is vital that all users read this information before using the Dewar and any
You find that the weight of the dewar has changed 3.8 kg over a 12-hour period. Using the National Institute of Standards and Technology fluids database, you see that liquid nitrogen at ambient (1 atm, 20° C) has mass of .86 kg/liter. Thus the NER would be: 3.8 kg change / 1/2 day = 7.6 kg/day
GENERAL DESCRIPTION. The cryopreservation vessel is a double-wall, vacuum-insulated vessel made of aluminum with a fiberglass composite neck, providing the highest efficiency possible in cryogenic temperature preservation. Use the vessel for liquid nitrogen only.
Allow liquid nitrogen to settle in vessel for 2 hours to completely cool inner. Fill the vessel to the desired level after the 2 hr settling (cooldown) time. If filling the dewar from a pressurized source, make sure that the source tank is at a low pressure. (22 psi or below).
