Portable Dewars for Liquid Nitrogen, Oxygen & Argon

liquid nitrogen tank / portable dewars

The CL/CLPB is an ideal liquid nitrogen (LN2) tank that works equally well with liquid oxygen or liquid argon. This line of portable cryogenic vessels is intended for low pressure transport and storage with conventional straight liquid dispensing.
