[3dem] liquid nitrogen supply lines

[r.mesman]

Hi David,In all older cryo sample prep equipment (Jet freezers, HPF, Freeze-fracture systems) the liquid nitrogen lines are made of copper tubing, so in principle it should work. If you use brass couplings to go from the nitrogen tank and to the flexible hose you also don't run the risk of galvanic corrosion between copper and stainless steel.Cheers,Rob---Dr. Rob MesmanPost-DocDepartment of MicrobiologyFaculty of ScienceRadboud University NijmegenHeyendaalseweg 135NL-6525 AJ NijmegenThe Netherlands
