Removal of Broken NMR Tubes

Drain Hole

Bottom View

If a sufficient length of tube is not exposed, shutdown the

instrument & unplug the power cord. Next, use the broken

tube removal tool to push tube up & out of the channel.

To do this, very carefully tilt the spectrometer onto its flat

back and remove the drain filter cap on the bottom of the

unit. It is safest to have 2 people perform this procedure

so that the unit does not drop. Next, push the removal tool

up through the drainage hole to expose enough of the

broken tube to grab.

When the tube is fully removed, place the spectrometer

back on the tabletop and rinse the tube channel with a

small amount of an appropriate solvent (e.g. Isopropyl

alcohol). Wait for the solvent to dry before plugging the

power cord in.

Never place the spectrometer completely upside down

If a tube is broken and cannot be removed by grasping the

broken end, first unscrew the white NMR tube guide. If this

exposes enough tube, grasp it with plastic (non-magnetic)

tweezers and pull up carefully in a linear motion.
