Dear All
I am pretty sure I am not the only one in Spinland that suffer from
this. The J-Young tubes that is used mostly by small molecule chemists,
repeatedly get stuck inside the magnet and a normal eject operation by
the user doesn't dislodge the tube. I have set a rule here not to spin
these sample tubes since they have a noticeable wobble due to the
dumbbell shape afforded by the spinner as well as the plastic seal that
keeps the atmosphere inside the tube in tact.
The remedy I use include, increasing of Lift Air flow to max,
increasing of VT air flow in combination with Lift Air flow and the last
resort, pulling the probehead out and use a plexiglass rod concoction we
have made (that has a funnel shape at the tip to cup around the tube
bottom) to push the tube out of the magnet.
Is there any other wizardry out there that this venerable group can
share with me that I can use to make my life easier ? Personally I have
already sustained a casualty once, while using the plexiglass rod, when
the same slipped and fell and landed on my left eye (I was lying down
under the magnet, guiding the rod through), causing a corneal tear.
Hope you guys didn't have to suffer any such mishap.
Thank you as always.
Best Regards
Rajan
