The tip is designed to never clog by hitting any ice debris inside the magnet. When the tip is inserted downward into the magnet, the slots in the tip point upward so the liquid helium or nitrogen can always emerge without obstruction. Turn this object over and look at it in your hand, and the slot angle might make it look like a little pine tree.
One can only wonder why the new helium transfer line does not come with an appropriate fitting.

Subject: AMMRL: Helium transfer 'Christmas Tree' fitting
A neighboring institution is getting a new Bruker 400 system installed and they've been told they need to get a 'christmas tree' adapter/fitting for their transfer line. Their engineer hasn't been to helpful telling them where to get one.
We have one that we've had for ever, but not really sure where it originated from.
Any suggestions? And how exactly did this thing come to be known as a christmas tree???
Thanks!!
