Transportation and storage as above. Liquid helium is considered a super-fluid inasmuch as it climbs walls and will go through molecular-size openings. Peter Wieck Melrose Park, PA |

In article ,
says... Liquid helium is considered a super-fluid inasmuch as it climbs walls and will go through molecular-size openings. Peter Wieck Melrose Park, PA That is if you reduce the pressure by pumping until the temperature drops to below about 2°A (see https://en.wikipedia.org/wiki/Superfluid_helium-4). I remember doing this and seeing the helium stop boiling energetically and go unnaturally calm. It was still boiling, of course, because heat was still leaking in... Mike. |

Helium will leak even in its gaseous state. Metalized Mylar balloons last much longer than latex, but they still fail far more quickly filled with helium than with air. The helium diffuses right through the material. Peter Wieck Melrose Park, PA |

The helium diffuses right through the material. Hence the need for a helium leak detector mass spectrometer. Anyone with this piece of equipment NEEDS a HLDMS to go with it. -- No deal? No problem! :-D |
